What is the best avalanche beacon for the backcountry? To find out we took 14 of the top models and put them through rigorous head-to-head tests in the Cascades, Sierra and Alaska. We had novices test them to see which is easiest to learn and use; then we put them in the hands of expert mountain guides and AIARE instructors who teach avalanche safety courses.

Pros Best range for a digital beacon, tons of features, preforms fantastically in the fine search and cool advanced user optionsLots of features, good range, fast processor, Best Battery life in our review, excellent flagging featureEasy to use, long range, may be the wave of the future.Very fast processor, crushes in the fine search, easy to use, light and compact: great for beacon-in-pocket usersExcellent Range, Lightning fast, Well labeled buttons and easy to use interface
Cons Expensive, fast processing but not the fastest.Battery life is only displayed in thirds and not a percentage.More experienced users will have to slightly retrain themselves, expensive.Display screen is just okay, multiple burial function un-suppresses the last marked beacon in only 1 min leading to confusing and wasting time, Can only mark one signalFlagging options were marginally more confusing at first, Harder during fine search than other beacons we tested.
Best Uses A fantastic beacon for intermediate through the most advanced professionalsProffesionals, ski guides, trip leaders and advanced backcountry travelersA great beacon for most noice to intermediate users through the most demanding avalanche professional.Good for beginger or intermediate users, but most appreciated by more advanced users intermedaiteAnyone from novice to expert

How To Choose the Best Avalanche Beacon
Below we break down the criteria we used for evaluation and present a few key pieces of information regarding avalanche beacons. Besides real world applications, we also performed a series of side-by-side tests to compare range, processor speed, flagging features, battery life and more. We break down the different models and their advantages and disadvantages. We also pick our Editors' Choice, the Best Buy and a handful of Top Picks for specific reasons, for user groups from novice to professional.

Ever wonder how do avalanche beacons work? Check out our How To Choose the Best Avalanche Beacon article on beacon fundamentals and current technology in addition to buying advice on key features and important factors to consider.

If you are heading into the backcountry, check out our Avalanche Airbag Review. Airbag packs aren't as essential as an avalanche beacon but they greatly increase your chance of surviving an avalanche.

A Note on Wearing an Avalanche Beacon
Statics
Statistically 38 people will die from avalanches in North America every year and 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 guarantee 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.
This graph excludes victims who die of trauma and emphasizes the impor...

Practice Makes Perfect
No matter how fancy a product you decide to purchase, training and practice are essential. The above graph emphasizes the importance of proficiency with the rescuers' beacon. Experienced backcountry enthusiasts and avalanche professionals can find multiple beacons in under six minutes, while the unpracticed novice can easily take 35 minutes or more. While the the average rescue time is heavily debated, it is generally thought that from the moment the person is caught in the slide to the time 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) or American Avalanche Institute (AAI) avalanche course.

Wearing an Avalanche Beacon
There are two locations on your body that are considered acceptable to wear one. The first is in your beacon's harness; this puts it in the largest "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 wear it on the outside of the outermost layer of clothing rather than underneath at least one layer of clothing because the odds of it getting ripped off your body are too high. The other acceptable location is in your pants on the inside of a zippered sewn-in pocket. Laminated pockets are not okay because these pockets have been torn off during an avalanche.

Don't keep your cell phone, radio or GoPro within 30cm of your unit, regardless of whether it is on or off. There have been at least two high profile deaths in the last three years because a cell phone interfered with the wearer's beacon. At least one of these cell phones was off. Recently there have been reports of heated gloves and boots causing interference.

Criteria for Evaluation
Range Comparisons
A Note on Range
A manufacturer's given maximum range is always measured with the searching beacon and the victim beacon in perfect orientation or perfect "coupling." While this is a standard among manufacturers and is the same format for our OutdoorGearLab Range test, it is important to note that it is unlikely you will get that much range in a real world setting because odds of getting that perfect alignment are slim. Almost all of the products we tested have a manufacturer's maximum range of between 40 and 60 meters. So if a perfect case range is 50 meters, its worst case range is 25 meters. Because most beacons cite 40-60m 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 30m wide search strip width; or 15 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, including the extremely popular first generation Tracker DTS.

Manufacturers' maximum distance ratings
While the manufacturer's range was fairly accurate, some of the time it was usually a bit further than we could pick up.

A note on the distance numbers
The units (IE numbers) that describe distance along the flux line that we follow to find our victim are usually not actually meters. For example, when we picked up a signal with a Tracker 2 while it was reading 47 meters, we were actually around 42 meters away. In our tests the only products where the number was accurate were the Mammut Barryvox Element and the Mammut Pulse Barryvox. Most units displayed a greater number of meters than was the actual distance. The Pieps were the most notorious at this.

OutdoorGearLab Range Tests
We tested all of the contenders' ranges on a high school football field. We started out of range with as optimal a coupling as we could get with the target beacon 85 meters away. Our test product was at waist level in a typical searching position. We marked the place we first picked up the signal; those with the longest range were entirely analog or had an analog function. These included the Ortovox F1 (76m), the Mammut Pulse Barryvox (72m) and the Arva Pro W (62m). Both the Mammut Pulse and the Arva Pro W could pick up a beacon in analog 13-19 meters further away than when they were in digital mode. While we agree analog 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 effectively, we primarily reported each product's maximum digital range.

After countless tests and comparisons the products with the longest range were the Mammut Pulse Barryvox, Mammut Barryvox Element and Arva Neo. They could sometimes receive signals just below 60 meters and were our top performers in this category. Just barely behind were the Ortovox S1+, the Pieps DSP Pro and the Arva Pro W. All of these had ranges on either side of 50 meters. Next, it was just below a 10-meter gap before the next group, which included the BCA Tracker 2, Ortovox 3+ and the Pieps DSP Sport.

Speed
Our speed category measured how fast we could find a victim with a given beacon, start to finish. While speed takes into account several other categories we used in our criteria for evaluation, speed has some of its own, the most important being processor speed, dealing with both a single burial and multiple burials. To test speed we compared all 14 products side-by-side over several days with well over 200 tests performed. We also let everyone, from relative novices to seasoned avalanche instructors, test them to give a broad insight into each contender's performance. In the end the fastest performers weren't always the most expensive nor the most feature rich options. In fact, 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 quick because of their processor speed were the BCA Tracker 2, Tracker3, the Arva Neo, Otyovox 3+, the Pieps DSP Sport and the Pieps DSP Pro. The Ortovox S1+, Mammut Pulse Barryvox and Barryvox Element and Ortovox Zoom+ were just a touch slower. We were a little disappointed with some of the simpler options like the Arva Evo3+ and the original Tracker DTS. They did okay, but were not as quick as other "simple" beacons.

Ease of Finding a Single Victim
This is the most basic but most important difference consideration when choosing an avalanche beacon; in our scoring we weighted this category the most heavily. One of the biggest differences comes in how they deal with signal spikes. All the three antennae models did great, while the older or less expensive double or single antenna designs like the Pieps Freeride, Ortovox F1 or the older Tracker DTS had their shortcomings.

Interface and Controls
How easy and intuitive the controls and interface are had a direct correlation with how fast rescuers found beacons, both expert and novice alike. Along with the user interface are the actual controls that help you navigate through menus, go from send to search and flag a buried beacon.

Our favorite controls for simple models were on the BCA Tracker 2 and the Ortovox Zoom+. Both models have simple and intuitive controls that are easy to understand and operate. While they don't have any of the more complex features like a flagging feature, or options on various functions, both are hands down the easiest to use. For the mid-level complexity models, referring to models that had a search and send feature and flagging/marking function, the Arva Neo, Ortovox 3+ and the Pieps DSP Sport were surprisingly easy to understand and intuitive to use. Among the most complex models, we like the user interface and controls of both the Ortovox S1+ and the Mammut Pulse Barryvox. This is one area where one of our top scorers, the Arva Pro W, didn't do as well. Even compared with other complex, feature-rich products, the Pro W was a little harder to use; the menu wasn't as intuitive and it took a little longer to get the hang of it.

Ease of Use in Fine Search
The fine search is the final phase of the total search and involves the final approach and bracketing stages. It is important to slow down during this stage, but this is also the phase of the search where you can see the greatest difference between products with respect to processing power. They don't all have the same precision; some were slightly better than others at getting the victim in the center of our brackets. The Mammut Pulse Barryvox and Element performed near the top again, along with the BCA Tracker 2, Pieps DSP Pro, Pieps DSP Sport, and Arva Neo. The Ortovox 3+ and the Arva Evo3+ were slightly less precise at having our victim in the center of our brackets.

Ease of Use in Multiple Burial Situations
Multiple burial situations is where the competition differed the greatest. It is more important to 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 is 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 with any beacon that multiple burials are always harder and take even more practice than single burials. After dozens of tests and comparisons, the undisputed best products for multiple burials are the Mammut Pulse Barryvox and the Ortovox S1+. Both of these could handle a lot of signals well. Even if two were buried close together, the S1+ and the Pulse were up to the challenge. Both the S1+ and the Pulse allowed their user to scroll between previously flagged beacons. Other products that performed as well with two or three beacons and nearly as well with four or more beacons were the Pieps DSP Pro, Arva Neo, Ortovox 3+ and Arva Pro W. All of these products could handle four signals, just not as solidly as the S1+ or the Pulse. The Neo, DSP Pro, Pro W and 3+ all had functional and intuitive flagging/marking functions and performed fantastically with up to three beacons. The DSP Pro and the Arva Pro can also unmask previously marked beacons.

Other Features
Revert to Transmit Mode
Some of the models we tested had a Revert to Transmit feature. 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 major movement during a designated time period. The idea behind this feature is if the rescuer is searching and their beacon is in search mode and they are hit by a second avalanche, it will switch over in hopes that they can be located. The models that we tested that have a Revert To Transmit mode are the Ortovox S1, Ortovox 3+, Tracker3, Arva Pro W, Arva Neo and the Mammut Pulse Barryvox. The new Pieps Sport and Peips DSP Pro have this feature but you can't set it up in the field. You must set it up at home by plugging the Pieps data cable into its headphone jack. On the flip side, 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 beacons 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 Pro W, Arva Neo, Barryvox Pulse and Ortovox S1+.

The Plus/Minus of Revert to Transmit Mode
The Revert to Transmit mode is sometimes a controversial feature. Its importance is sometimes over-emphasized and some manufacturers, including Pieps, 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 you are hit by a second avalanche? Because if you are searching for someone your beacon is likely in your hand and if you are hit by a second avalanche there is almost zero percent chance that the you will be able to hang onto it. The elastic leash attaching the beacon to the wearer's chest harness is also almost certain to snap. So while we took this feature into consideration when weighting all of the products we tested, we didn't count it as a big factor.

Built-in Compass for Fine Search
A cool feature that some models have is a built-in compass feature that proved especially helpful in the fine search. These indicate whether you have gone to far and 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 that have this compass feature are the Mammut Barryvox Pulse, Arva Link and Ortovox S1+.

Proprietary Beacon Technology
The W-link Frequency
The W-link frequency was developed in conjunction with both Mammut and Arva to create their Pulse and Pro W models. We expect to see more beacons using W-link frequency technology in the future. The W-link is a separate frequency that broadcasts in conjunction with the standard 457 kHz. The W-link allows the beacon to transmit additional information to assist other W-Link enabled beacons and more accurately pinpoint other W-Link beacons. This is the frequency on which the Mammut Pulse Barryvox transmits its Pulse feature movement information.

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 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 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 like the Pieps DSP Pro offer a scanning feature that helps advanced rescuers in complex situations asses how many victims there are and how far away they are, rather than just showing the closest signal. The BCA Tracker3 has a BP or Big Picture mode which, when turned on, displays the distance and a direction for every signals it picks up, quickly cycling through all of them in rapid succession. This is similar to an older analog style beacon or a Mammut Pulse Barryvox in analog mode.

Durability
With the exception of 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 effect 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.

Editors' Choice – Best Avalanche Beacon
The Mammut Pulse Barryvox is our top scorer and winner of our OutdoorGearLab Editors' Choice Award. The Pulse scored at or near the top in every category. Although one of the most complex, feature-rich models on the market, most people still found it relatively easy to use. The Pulse also has has the longest range, was among the fastest and deals the multiple burials exceptionally well. What's the disadvantage? The Pulse is, the along with the Ortovox S1+,the most expensive in our review. The Pulse can also be a little overwhelming for some users.

Best Buy – Best Value Avalanche Beacon
Our new OutdoorGearLab Best Buy Award goes to the Pieps DSP Sport. It retails for only $275, one of the least expensive models in our review and also the cheapest triple antenna option. Being inexpensive certainly doesn't make it incapable. The DSP Sport has the longest range and is one of only two products that have a flagging/marking feature for under $335. Also among sub $335 options is the Pieps DSP Sport, which is one of the easier to use and has one of the fastest processors during every stage of the search.

Top Pick Award Best Value for advanced users: Pieps DSP Pro
The Pieps DSP Pro is one of the most advanced models in our review at a very competitive price. It has similar functions, function options, range, and processor speed to most of the other beacons that cost $100-$125 more. For that reason it is one of our OutdoorGearLab's Top Picks for best value for more advanced users. Even price aside the DSP Pro remains one of our favorites overall beacons and we love how ease it is to use. The Pro has a nice selection of more advanced features, like a frequency check, scan function and one of the best over-all multiple burial functions that handles complex mutual-victim burials wonderfully.

Top Pick Award – Best all-around beacon between $300-$400
The best product between $300 and $400 was a tough call because there are a lot of great options in that price range. This is also the price range that most consumers are looking in and most of the features these products have are geared toward the majority (novice through advanced) of users. That leaves only the most experienced guides and avalanche professionals to likely want something more expensive. After careful consideration, the OutdoorGearLab Top Pick Award for best all-around product between $300 and $400 goes to the Arva Neo. The Neo wasn't the runaway winner in this category, facing stiff competition from both the Mammut Barryvox Element, Backcountry Access Tracker3 and the Pieps DSP Pro. But in the end we picked the Arva Neo for its top end range, fastest-in-class processing, stellar user interface and easy to use and effective flagging feature. If you like the Neo but wish it had a couple more advanced features, check out the Mammut Element or the Pieps DSP Pro.

Top Pick Award – For Speed and Ease of Use
The Backcountry Access (BCA) Tracker 2 remains the fastest option for the novice and intermediate users…and it's still wicked fast for advanced users…for finding a single victim and it is one of the fastest beacons period. That's the straight up most important thing a beacon needs to do. While it does not have any of the more advanced features of some other products, the Tracker 2 serves the majority of users extremely well. If you like the Tracker 2 but wish it had a flagging/marking feature, check out the Ortovox 3+, which could move nearly as fast and is equally intuitive. It you like the Tracker 2 but wish it was even more simple, check out the Ortovox Zoom+.

Other Awesome beacons that narrowly missed being Top Picks
Backcountry Access Tracker3
The slick looking new Backcountry Access Tracker3 is the newest of the Tracker family. Like its relatives it crushes at finding a single victim and bracketing during fine search, where most rescuers struggle the most. The Tracker3 now adds a lot more features aimed at advanced users: a signal suppression/marking function and the best overall pocket-riding triple antenna beacon on the market. We liked nearly all of the Tracker3's features, (especially its BP or 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 the beacon reverts back to normal searching where the rescuer is directed to the closest beacon, regardless of which beacon 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. The Tracker3 remains a capable, lightning fast beacon that has some of the functionality desired by more advanced users.

Ortovox S1
The Ortovox S1+ was just barely edged out in our scoring by our overall Editors' Choice, the Mammut Pulse Barryvox, and is still one of our favorites. It is a previous Editors' Choice winner (2011) and when it came out we considered it a game changer. We still think one day other models will use similar technology as the S1+. What sets the S1+ apart is the fact it's the only option on the market that takes you straight to the victim rather than "hooking" around on a flux line. This plus its fast processor helped the S1+ to be one of the quickest we tested. It also handled multiple burials exceptionally well and as with single burials it displays them in a completely different way; it shows all the victims, each with its own distance number all at the same time, making it easy to keep track of them. Also, the S1+, like other high end products, has a dozen or so other features plus control of several options within each feature.
