Best Overall Avalanche Beacon
Black Diamond Guide BT
This Black Diamond Guide BT is one of our favorite overall beacons. The BT in this model's name refers to Bluetooth, as this model has software that can be updated; you can also adjust its settings via a downloadable app on your smartphone. The Guide is not only excellent for advanced users, but for all levels of users in the backcountry.
It performed very well in the fine search for a single victim and was consistently among the best for accuracy and placing the buried beacon at the center of the bracket. It was also one of the very best models at complex and close proximity burials, just beating out the Barryvox S in what are otherwise comparable beacons.

Best for Advanced Users
Mammut Barryvox S
The Mammut Barryvox S is an excellent beacon for advanced users traveling avalanche terrain. It's fast at finding a single burial and is adept at handling complex multiple burials. It sports numerous features to help customize it to its user's tastes and preferences and sports the longest overall range and widest search strip width of any model in our review. The Barryvox S is the newer version of an older award winner, the Pulse Barryvox. The newer Barryvox S shares many of the Pulse's best features while improving on its few drawbacks. The most notable improvement was speed while moving closer than 10 meters to a buried beacon, but specifically the quickness you could move in the fine search while bracketing.
While it is excellent for professionals and experienced users, it's not necessary for other backcountry travelers. It's overkill for many who could easily get away with a less expensive beacon, as they likely won't use a majority of the features this model has to offer. Its capabilities also equates to complexity — something that isn't particularly helpful for less experienced individuals when racing against the clock to save their friend's life. The Barryvox takes a little more practice to be precise in the bracketing stage than models like the Tracker3 or the Black Diamond Guide BT. The Barryvox S besti for more advanced users and pros who will take advantage of its many features and its top-notch ability to manage even the most complex multiple burial rescue scenarios.

Best Bang for the Buck
Backcountry Access Tracker S
The Backcountry Access Tracker S is the latest in the long line of intuitively designed Tracker beacons; the "S" is basically a slimmed-down version of the Tracker3. Built-in a similar low-profile casing as the T3, it's one of our favorite models for pocket-carrying backcountry travelers. The S in Tracker S is for a simple, though don't let the name lead you to believe this isn't an incredibly capable beacon. It also has nearly all of the features of the Tracker3, and continually impressed us for its speed and prowess. All of our testers loved how simple it was to use, and appreciated the speed of its processer. One of our favorite things was how precise it consistently was during the bracketing stage of the search, for both experienced and more novice users alike.
While this wasn't a dealbreaker, we didn't love the multiple burial function where it only suppressed the closest signal for one minute. This is fine the vast majority of the time, but in certain situations, it's a hassle; it's something you'll have to learn to be okay with, as no other manufacturer designs their flag/marking function this way. With the model we tested, it didn't quite live up to BCA's stated range in any of our tests and was notably shorter than the Tracker3. While more range is excellent, it still provides the 40 meter search trip that the majority of rescuers are going to use.

A Competent, Lightning Fast Model
Backcountry Access Tracker3
The slick-looking and low profile Backcountry Access Tracker3 is the latest and greatest of BCA's Tracker family. Like its relatives, it's excellent at finding a single victim and makes bracketing during fine search exceptionally easy. It is also the most accurate, and shows the buried beacon in the dead center of their bracket. Both of these aspects are particularly nice, as this is where the majority of rescuers struggle the most. The Tracker3 takes the ease-of-use and lightning-fast processor speed of the Tracker2 and adds a handful of features aimed at more advanced users; most notably a signal suppression/marking function and a low profile, making it one of the best overall pocket-riding triple antenna beacons on the market. We liked nearly all of the Tracker3's features, (especially its Big Picture function) and its control options.
We liked the accuracy of the signal suppression/marking function, but didn't like that the suppression only lasted for one minute. After that one minute, it reverts to normal, searching where the rescuer is directed to the closest beacon, regardless of which one that is. While less of an issue in real-world settings, we also didn't love that the Tracker3 can only suppress one signal at a time; if you try to suppress a second, it undoes the first. This takes a little more practice for pro-level examinations and is worth noting, as it is different than the rest of the industry. With that said, the Tracker3 remains a competent, lightning-fast model that has some of the functionality desired by more advanced users.

Notable Value for Speed, Ease of Use, and a Solid Flagging Feature
Black Diamond Recon BT
The new Black Diamond Recon BT is more-or-less identical to the Pieps Powder BT, which is branded under the Pieps name (BD has owned Pieps since around 2012). The Recon is the more basic version of the award-winning Guide BT. While the Guide BT received an award for its exceptional all-around performance and array of features, we think the Recon BT is better-suited and more than adequate for the majority of backcountry travelers. Most folks will rarely take advantage of all the features on the Guide BT, whereas the Recon has more basic performance characteristics and a handful of features that beginner to experienced users tend to look for. The BT in this model's name refers to Bluetooth, as it can be updated and configured via a Smartphone app.

We extensively tested all the beacons in our review, pitting them head-to-head in both single and multiple burials, timing and analyzing each model's performance at each stage of the search in the hands of both professionals and more novice users. We compared each model's performance and accuracy in the fine search and the consistency and precision of their brackets (boxes). We also performed controlled range tests, starting outside the beacon's maximum range, and moving in until detection to avoid single drag error and performed this on two separate occasions with each model. We looked for consistency and repeatability of each model's performance along each stage — as well as across user types — to best assess the pros and cons of each model.

Analysis and Test Results
Below we present key pieces of information regarding avalanche beacons and the criteria we used for evaluation. Besides real-world practice with individual beacons, we also performed a series of side-by-side tests to assess processor speed, bracketing/fine search performance, flagging/marking features, battery life, range, search strip widths, and more.
Related: Buying Advice for Avalanche Beacons
We highlight awards for specific users, and like most things, generally speaking, the more you spend, the more featured the beacons become. However, with beacons, the most capable and featured filled beacon might not be the best for everyone. For example, the most capable beacons are often more complex and have less straightforward use; this might suit a pro perfectly but wouldn't be the best for a more novice user or someone who doesn't practice as frequently.
To some extent, beacons are also like a more manual camera; sure, it can do more, but you have to know more about operating it to get more out of it. If you don't plan to use all the manual features, you are better off getting a beacon that might have fewer options on how to manage certain settings. As a result, it just does it for you and will be easier; something most people can appreciate in a stressful situation.
We made sure to highlight a handful of models that perform well and cost less, so you're able to see the highest value for the best price. One beacon that fits this description is the Backcountry Access Tracker S. At its price point, it's an extremely capable beacon — the best option for the price. While we like other models slightly better, this is a very solid beacon for the price because it is so fast and easy to use.
Overall speed, along with ease of finding a single victim, should be the single most important factor folks consider when purchasing a beacon. While all the cool extra features are rad and easy to focus on, speed and ease of finding a single buried beacon should be your strongest considerations. Our speed category measured how fast we could find a victim with a given beacon, start to finish. While speed considers several other categories, such as precision in the fine search and ease of locating a single victim, we gave it an accumulative score for our criteria in our evaluation. This is because it takes into account parts of other categories and several of its own, with the most important being processor speed.
We compared all products side-by-side over several days, with well over 200 tests performed. We also tested models with a wide range of user abilities, from relative novices to seasoned ski guides and avalanche professionals, to get a broad insight into each model's performance. In the end, the fastest performers in simple, single transceiver burials weren't always the most expensive or the most feature-rich options. In these types of scenarios, we found several of the more complex models to be slightly slower than their more basic counterparts.
The models we found to be the most lightning fast thanks to their processor speed were the BCA Tracker S and Tracker3, with the Black Diamond Guide BT, Black Diamond Recon, and Pieps Micro following closely behind. Only a small notch slower yet was the Mammut Barryvox and Mammut Barryvox S, performing only every-so-slightly slower. We were a little disappointed with the original Tracker DTS and Ortovox Zoom; these models did okay but were not as quick as other "simple" beacons.
Ease of Finding a Single Victim
Finding a single victim is the most basic but most important feature of any beacon and shouldn't be overlooked when considerating your selection. As such, we weighted this category the most heavily. We emphasize this category because statistically speaking, in North American, roughly 85% of the time, rescuers are searching for a single burial beacon. The other 15% of the time, where multiple people/beacons are buried, a majority of rescuers won't have the resources to divide and conquer and will likely focus all of their effort on locating and digging up one victim at a time.
For example, two rescuers looking for two buried beacons will essentially complete two independent single victim searches, one immediately after the other. Additionally, we considered the "ease of use," taking into account the simplicity and functionality of the interface, the controls, and the processing speed.
Interface and Controls
How easy and intuitive the controls and interface has a direct correlation with how quickly rescuers were able to find a buried transceiver, something that we found true with both experts and novices alike. Along with the actual user interface (how the beacon directs/displays to you where to go) are the controls themselves that help you navigate through menus, go from send to search, and flag a buried beacon.
The simplest model to use were the BCA Tracker2 and the Ortovox Zoom+. Both models have intuitive and straightforward controls that are easy to understand and operate. While they don't have complex features, like a flagging feature, or options on various functions, both are hands down the easiest to use.
Among the more fully-featured models, which are models that have a search and send feature and flagging/marking function, are the Backcountry Access Tracker3, BCA Tracker S, Black Diamond Recon BT, Arva Neo, and Ortovox 3+; they are also surprisingly easy to understand and intuitive to use. Among the most complex models are the Black Diamond Guide BT, Mammut Barryvox S, and the Arva Axio. Each of these beacons had fairly simple functionality for basic uses; optimizing the potential takes more practice and time reading the manual, as you should with any beacon.
Ease of Use in Fine Search
The fine search is the final phase of the beacon search and classically involves the final approach below 10 meters and the bracketing stages. This is the part of the search that rescuers struggle with the most. Regardless of the beacon, it is essential to slow down during this stage; however, even then, this is also the phase of the search where you can see the most considerable difference between products concerning processing power, precision, and ease-of-use.
When it came to the fine search, we found a lot of variability in the precision; some were slightly better than others at getting the victim in the center of our brackets more efficiently.
This assessment came from consistency of dozens of tests, with the models consistently scoring the best. These models include the Mammut Barryvox S, Tracker2 and 3, Tracker S, Pieps Micro BT, and the Black Diamond Guide BT and Recon BT.
Maximum range is important, but it isn't nearly as critical as the categories we've mentioned above. People often like to put a lot of weight in a given model's maximum range because it's an easier quantifiable number, but that doesn't make it more important. While no one will argue more range isn't nice, having say a 60 meter range over a 45 meter range will have a minimal difference in reducing rescuers overall time for the reasons listed below (regarding search strip width).A Note on Range
A manufacturer's stated maximum range is always measured with the searching beacon perfectly in line with the transmitting beacon, which is considered perfect orientation or perfect "coupling." This is a standard for manufacturers and is the same format for our in-house range test. It is important to note that it is unlikely you will get that much range in a real-world setting because the odds of getting the perfect alignment are extremely slim.
Almost all of the products we tested have a manufacturer's maximum range of between 40 and 60 meters. It is worth noting that if a perfect scenario range is 50 meters, then its worst-case range is 25 meters. Thus when most beacons cite 40-60 meters of maximum range, it means they have 20-30 meters of worst-case range. This is why AIARE and other avalanche educational organizations teach the rescuer to search with a 40-meter wide search strip width, or 20 meters of range on either side of you. That way, you could pick up the signal, even with the poorest coupling and a beacon with the lowest possible range.
Manufacturers' Maximum Distance Ratings
While most manufacturer's range was reasonably accurate, some of the time, it was a bit further than we could pick up in our tests. To insurance accuracy, we did multiple sessions of testing; one on a dry football field and one in the mountains in a remote parking lot.
A Note on the Distance Numbers
The units (IE numbers) that describe distance along the flux line that we follow to find a buried transceiver are typically not meters (but are often close). For example, when we picked up a signal with a Tracker3 while it was reading 47 meters, we were around 42 meters away (even in perfect coupling, reducing an effect of the curvature of the flux lines).
In our tests, the only products where the number was accurate or extremely close to being accurate were the Mammut Barryvox and the Mammut Barryvox S. Most units displayed a more significant number of meters than the actual distance. The Pieps and Black Diamond models were the most notorious for this, often giving a much larger number than we observed in our testing. While we think better accuracy is slightly better, this doesn't have an effect on actual performance; it is just something to be aware of.
We tested all of the ranges on a high school football field. We started with optimal coupling, as we could get with the target beacon 100 meters away (adjusted for meters despite the yard marks on the football field). Our test product was at waist level in a typical searching position. We marked the place we first picked up the signal; we would rarely get the same spot with the same beacon, so we either mention the general range we picked up the beacon on or an average of those attempts.
Those with extended ranges were entirely analog or had an analog function. The model with the longest range was the Mammut Barryvox S, which could pick up a signal as far away as nearly 90 meters in analog mode and 72 meters in digital mode. It is worth noting that while we agree analog function is a cool feature, few people know how to accurately use the analog function effectively enough so that it speeds up the rescue. Because it doesn't aid most people's search efficiently, we primarily reported each product's maximum digital range even if they have an analog mode. In digital mode, both the Mammut Barryvox S and the more standard Barryvox still offered the longest maximum range, consistently picking up a signal at around 70 meters away, and both coming with manufacturers search strip with recommendations of 70 meters.
After countless tests and comparisons, the products with the next longest ranges were the Arva Neo, the Black Diamond Guide BT, and the Black Diamond Recon BT. These models would most often pick up their signals around 50-55 meters away and were our next round of top performers in this category.
Ease of Use in Multiple Burial Situations
A Note on Multiple Burials
Roughly only 15% of reported avalanches in North America and Europe are instances where multiple people are buried in a single avalanche occurrence. For those curious, of that 15%; 10% of the time, there are two people buried, and the other 5% of the time there are three or more victims.
To be in a situation where you need to use a flagging/marking function on a beacon, you likely need several rescuers. If you have multiple people buried and three or four rescuers, all of those rescuers' effort should likely go into finding one person quickly to give that person the best chance of survival.
Once you get to your formerly buried partner's airway, you could choose to flag them to save the effort and time of turning their beacon off. However, turning it off is the most foolproof way to deal with the situation and will take away any doubt or future confusion later, depending on your rescue skills. For ski guides, ski patrollers, or other avalanches professionals, a dependable rescue flagging/marking functionality and a beacon's ability to handle multiple close proximity burials is essential for training and examinations.
For your beacon to be able to tell other buried beacons apart, it uses a blend of signal strength and cadence (each model has its own magic blend of these two). When two buried beacons are close together, the difference in strength becomes minimal, and your beacon can only rely on cadence (or the pulsing "beep" off each beacon). If there are three or more beacons buried even slightly near each other, they will have too much signal overlap, and your beacon will have a very difficult time differentiating a specific beacon's cadence from another and potentially won't be able to accurately mark/flag/suppress a specific beacon.
Universal Multiple Burial Techniques
Knowing and having practiced with your beacon's specific masking/marking/flagging function is useful; you need to be familiar with your beacon. Two universal multiple burial techniques will work with any beacon, eliminates the need for flagging, and works fantastically with multiple beacons in close proximity. They are the concentric circles method (sometimes referred to as the three circle or expanding circles method) and micro strip searching technique. With either of these techniques, a fast processing beacon is crucial to moving quickly, but again, no flagging function is necessary.
Our Findings From Side-by-Side Comparisons
Multiple burial situations are where the competition differed the greatest. Again, our professionals find, probe, and dig up a single victim rather than just flagging/marking multiple victims without digging them up. Consequently, we more heavily weighted speed and ease of finding a single victim in our scoring. But with that said, multiple burials are still a factor to consider. We performed our side-by-side comparisons tests with two, three, and four buried beacons to see how well each model resisted getting bogged down. Keep in mind that with any beacon, multiple burials are always harder and take even more practice than single burials.
After dozens of tests and comparisons and facilitating AIARE Pro level multiple beacon search assessments, the undisputed best products for multiple burials are the Mammut Barryvox S and Arva Axio. These two beacons differentiated between close proximity burials exceptionally well and could scroll through victims, and were extremely difficult to fool the marking/masking function. They also both offered the ability to unmask previously marked beacons.
The BCA Tracker3, Black Diamond Guide BT, and Black Diamond Recon BT all did nearly as well in our multiple burials test and would likely do extremely quite well in most real-world situations.
This category showed the most variability between the different avalanche beacons that we tested. Some come laden with useful and well-thought-out features, while others have limited options. Here's how we scored the different models on their features, and below we describe the different feature options currently available on the market today.
Group Check Mode
Several beacons in our review feature a "Group Check Mode" designed to be used during the function check that every backcountry traveler should be doing before leaving the trailhead every time they go out into the backcountry. A group check mode helps models with stronger signal lock or the design functionality to lock onto the closest beacon and then stay with it for short periods, even if they start moving further away. There are advantages and disadvantages to strong signal lock, such as the advantage to differentiate close proximity burials to its user.
However, for this portion of the review, a strong signal lock can make it difficult to perform a function check if there are more than just a few other people in your group. We liked the easy access and visual aids of the Barryvox S and Barryvox, which were different despite so many similarities between these beacons, along with the Arva Axio, Black Diamond Guide BT, and Recon BT. We liked the Pieps Micro, but they just weren't quite as user-friendly as far as getting to them and using them. Models like the BCA Tracker3, Tracker S, Pieps Micro BT, or the Arva Evo5 don't have strong signal lock and jump easily from one to another, always locking onto the strongest signal. This made it much easier to perform a function check/group check and was better for micro strip-searching but took more care and skill if two beacons were buried extremely close to one another.Revert to Transmit Mode
Some of the models we tested had a revert to transmit feature (also known as auto revert). This feature has the unit automatically switch from search mode to send mode if there has not been any user interaction, like pressing a button or significant movement during a designated period. The idea behind this feature is if the rescuer is searching and their beacon is in search mode, and a second avalanche hits them, it will switch over in hopes that they can be located.
In most models we tested (that have a revert to transmit mode), it comes ready to use. Some models like the Black Diamond Guide BT have a revert to transmit mode that can be configured via Bluetooth with your smartphone, while others have this feature, but you can't set it up in the field. With the Tracker3, if you want the beacon to revert to transmit, you need to turn that function on every time you turn on your beacon — otherwise, it won't revert. We liked models that gave the user the option to turn this function on or off. We gave higher scores for beacons that took it one step further by allowing the user to select the amount of time to pass before the beacon reverted to sending. Beacons that had this feature where the Arva Axio, Barryvox S, and Barryvox.
The Plus/Minus of Revert to Transmit Mode
The revert to transmit mode is sometimes a controversial feature. Its importance is sometimes overemphasized, and some manufacturers, don't recommend it (and intentionally manufacture their beacons without it). Why wouldn't you want your beacon to automatically switch back from searching to sending in the event a second avalanche hits you? Because if you are searching for someone, your beacon is likely in your hand, and if a second avalanche hits you, there is almost zero percent chance that you will be able to hang onto it. The elastic leash attaching the beacon to the wearer's chest harness is also almost sure to snap. So, while we considered this feature when rating all of the products that we tested, we didn't count it as a significant factor.Turn-Around Indicator in the Fine Search
A cool feature that some models have is a built-in compass or turn-around feature, which proved especially helpful for newer users in the fine search. These indicate whether you have gone too far and need to turn around, unlike Pieps or Tracker beacons, where the arrow still tells you to go straight ahead. The only indication that you need to turn around is the distance numbers. Products with this compass feature are the Mammut Barryvox S, Arva Axio, and Arva Evo5.
Smart Antenna Technology
This is a feature developed by Ortovox that we expect to see other manufacturers use in the future. Any unit using this type of technology figures out which of the antennas is at the best orientation to broadcast from. With most other products, if the primary transmitting antenna is oriented vertically, the range at which other beacons will be able to pick up the buried beacon is dramatically reduced; it could potentially be only 50 percent of the maximum range. The Smart Antenna or similar technology uses gravity to determine which is the best antenna from which to transmit. Smart Antenna Technology helps beacons be found more easily by optimizing antenna position, rather than helping a beacon search better.Isotech Technology
With most triple antennas models, only two of the antennas are used to search for a signal, and most of the time, one of them is implemented far less than the other. This affects the beacon's maximum range, and thus, the search strip width that should be used. The Arva Neo is one of the first products to equally power both of its antennas. This means that the Neo has no worst-case orientation and maintains close to its maximum range regardless of orientation or coupling.
Scanning Functions and Big Picture Functions
Several beacons offer a scanning feature that helps advanced rescuers assess how many victims there are to locate and how far away they are, rather than just showing the closest signal. The Black Diamond Guide BT has this Fish Finder style application where it will tell you how many signals it is picking up in specific distance ranges. The BCA Tracker3 has a big picture mode, which, when turned on, displays the distance and a direction for every signal it picks up, quickly cycling through all of them in rapid succession. This is similar to an older analog style avalanche beacon or a Mammut Barryvox S in analog mode.
Except for the first generation BCA DTS Trackers, whose antennas are marginally more vulnerable to being cracked because of their location within the beacon, there isn't much difference in durability among beacons. With all of them, it's important to remember that they are fragile pieces of life-saving equipment, and owners should do their best to protect them. Avoid impact or unnecessarily leaving them out in the cold (such as in your car) overnight, which can lead the antennas to de-tune. If the antennas become damaged, even a little crack, it can dramatically affect its ability to search, as well as someone else's ability to save you. This is especially obvious under five meters during the fine search. As far as one company's antennas being more long-lasting and resistant to de-tuning compared to others, we couldn't find a major difference.
This review is designed to help lay out the differences between the avalanche beacons on the market today. The products in this review are meant to enhance safety in the unfortunate event you or someone around you is caught and buried in an avalanche. When it comes to safety, making a selection can be an overwhelming task; remember you aren't necessarily buying this beacon for you, but rather your partners, friends, and backcountry partners. With all the ways you could save money, an avalanche beacon is likely not the best start.
A Note on Wearing an Avalanche Beacon
On average, 36 people die from avalanches in North America every year, and around 185 people worldwide. In North America, roughly one-third of those deaths are a result of trauma, and the other two-thirds are a result of asphyxiation. Wearing an avalanche beacon doesn't ensure survival in an avalanche, and the fact that you are wearing one should not persuade you to ski, snowboard, or snowmobile in a way you otherwise wouldn't.
Practice Makes Perfect
No matter how fancy a product you decide to purchase, proper training and practice are essential. The above graph emphasizes the importance of proficiency with a rescue beacon. Experienced backcountry enthusiasts and avalanche professionals can find multiple beacons in under six minutes, while the unpracticed novice can easily take 25 minutes or more. While the average rescue time is heavily debated, it is thought that from the moment the person is caught in the slide to the time the victim's airway is exposed on the surface is around 20 minutes. Wouldn't you and your partners like to be on the faster side of that average?
We recommend taking an AIARE (American Institute for Avalanche Research and Education), American Avalanche Institute (AAI), or other American Avalanche Association (AAA) recommended avalanche course. Additionally, if you haven't taken one in the last 5-10 years, you should consider retaking one since a lot has changed with recent studies. It would be extremely rare for a person not to find retaking a Level 1 useful, even if they have taken a course several years prior.
Wearing an Avalanche Beacon
There are two locations on your body that are considered acceptable to wear an avalanche beacon. The first is in your beacon's harness not exposed to the outside (i.e., covered up); this puts it in the most significant "target area" on your body, and it's slightly more protected from impact. While wearing the beacon in its harness, it is not acceptable to have it exposed to the outside. It needs to be underneath at least one layer of clothing because the odds of it getting ripped off your body are too high otherwise.
It is not okay to have the beacon uncovered no matter how hot it is, or how cool you think it makes you look. The other acceptable location is in a zippered pants pocket. The pants pocket needs to be an internal (i.e., inside hanging) zippered sewn-in pocket. Laminated pockets are not okay because these types of pockets have been torn off during an avalanche. Despite worry from some readers, there has never been a reported case of someone having their pants ripped off in an avalanche with their beacon inside.
Don't keep your cell phone, radio, GoPro, or any other device that broadcasts a signal within 30 cm of your avalanche beacon. There have been at least two high-profile deaths in the last three years because the cell phone interfered with the wearer's beacon. At least one of these cell phones was off. Recently, there have also been reports of heated gloves and boots causing interference.
