Our Verdict

The Arva Axio is one of the most capable beacons in our review, particularly in complex multiple burial situations. Its extra-long fold-out third antenna helps differentiate between signals nearby burials, and the ability to toggle through victims along with an analog feature lets the user micro-strip search when the going really gets tough. The Axio was one of the toughest beacons to confuse, and it miss-marked/miss-flagged beacons the least along with the Mammut Barryvox S.
Tons of features
Excellent multiple burial features and performance
Differentiates close proximity burials very well
Long-ish range
Analog mode to help with micro-strip searching
A little chunky and slightly slightly bulkier for pocket carriers
One of the more complex interfaces
Slightly slower than top beacons in the fine search
Arva discontinued the Axio in 2021.

Our Analysis and Test Results

The Arva Axio is packed full of rad features and is one of the most capable beacons in complex rescues and pro-level examinations. While on the spendier side, it's a good value for advanced users and pros who will take advantage of the unique functions and design features. While this beacon works well for novice users, it will equate to more money for features and capabilities that may not used often.

Performance Comparison

The Axio has a maximum range of around 50 meters and a recommended search strip of 50 meters. While that is still a longer-than-average range and a wider search strip width than is recommended by AIARE, AAI, the CAA, and other avalanche educational entities, it is the shortest of all the most advanced high-level beacons.

The Axio uses five primary directional arrows coupled with four smaller sub arrows to help the user stay on the flux line. Once we got below 10 meters the beacon made a distinct tonal change, signifying that the user should move the beacon to the surface of the snow.

This beacon's above average processor speed is in line with other top beacons, like the Ortovox S1+ and Mammut Barryvox. On average, it wasn't quite as fast as some models when it came to finding a single burial, particularly for newer users who would benefit from keeping directional arrows down to two meters instead of three meters. Both Tracker models and the BD's directional arrows disappear at two meters, signifying the rescuer to keep the beacon in the same orientation and start bracketing, while that happens with the Axio at three meters.

Ease of Finding a Single Victim

The Axio performed above average at finding a single victim. Its longer than average range helped us quickly acquire a signal, and during the coarse and fine search, the Axio's speedier-than-average processor enabled us to move quickly.

It uses five primary directional arrows and four smaller sub arrows to help its user stay on the flux line. Once you get below 10 meters, there is a very distinct tonal change, signifying that the user should move the beacon to the surface of the snow.

Ease of Use in Fine Search

The Axio's directional arrows can be set to go away at either five or three meters. All of our testers preferred to have the directional arrows longer, as they helped us to get closer before the bracketing stage/fine search.

Once inside three meters (or five depending on what you choose to set it at), the screen displays numbers in the middle and four arrows, pointing out in the main cardinal directions. This display signifies to the user that they should keep the beacon in the same orientation and proceed with the bracketing stage. We will say that more novice users will need to practice bracketing more with this beacon than a BCA Tracker3 or Tracker S, whose arrows go away at two meters. For more experienced users, having arrows disappear at three meters versus two didn't make as big of a difference.

The Axio preformed above average in our side-by-side testing during the fine/bracketing stage of the search. The one thing worth noting is that unlike BCA and Pieps whose arrows disapear at 2m, the Axios arrows disappear at 3 meters. While not a big deal particularly with more experienced users, less practiced users would generally take longer to bracket than with other models.

Ease of Use in Mulitple Burials

The Axio is one of the best models for multiple complex burials and pro-level rescue drills. It will show up to five figures, indicating that it sees up to five signals, and a plus symbol for more than five. After extensive side-by-side testing, it proved to have one of the more effective markings/flagging functions, and it rarely got confused even with several close proximity burials. This is at least partially due to its fold-out third antenna, which, when opened, instantly turns the beacon into search mode.

The third antenna is much longer than any other model we tested, helping to differentiate between close proximity burials. Most model's third antenna length is limited by the thickness of the beacon; however, with this model, it is at least three times as long because of its fold-out design. The Axio offers several features to help it more effectively deal with multiple burials. The first such feature is how it easily lets you toggle between victims. This is nice in the event of lots of rescuers where you have several people digging, and you move on to the next beacon. In fact, in a pro-style rescue drill, we opted not to flag with this beacon and instead to toggle, so we didn't get confused. This feature can also help orient you to the situation; from a given point, you can see how far each beacon is from you.

The Axio also has an analog mode to use when in close proximity to the buried beacons. It is activated (when in search mode) by pressing the power button, which prompts the display to ask you if you want to go into analog mode. This feature was also especially useful for micro-strip searching close proximity burials in pro-level exams.

Differentiating close proximity burials is the peak of difficulty with any beacon. That is why Arva designed their Axio to have a much longer, fold-out third antenna which did a fantastic job of managing close proximity burials. Opening this folding antenna is also what turned it into Search mode.

The Axio is loaded with features and received a perfect score for this category. Not everyone needs all of these features, but for more experienced users, this beacon, along with the Mammut Barryvox S, is essentially the manual camera of avalanche beacons: more capable but need more practice to be proficient with.

Group Check Mode

The Axio sports one of the easier to use group check modes. After you power the beacon on, the screen will ask you if you want to run the beacon in group check mode. To enable this mode, simply unfold the third antenna. The screen will display GCHECK and significantly shorten its range. It will still display distance and give audible tones; once the other beacon is inside two meters, you will have the option to flag it and move on to the next beacon you're testing.

We liked a lot of things about the Axio but it is one of the bulkier beacons out there. It isn't huge and is similar to the Pieps DSP or Ortovox S1 it isn't near as small as several other models on the market.

Comfort to Carry

The Axio is a thicker than some, and as a result. feels slightly chunky. Its harness is comfortable, so this more of a small issue for those who like to carry their beacon in their pocket.

Controls and User Interface

The Axio's basic functions are relatively easy to use. It sports an “On” button on the left-hand side of the main body and a single red joy-stick directly below the screen that helps you navigate menu options and function as a select/flag icon when this button is depressed. The red arm that turns the beacon into Search mode and contains the third antenna doesn't do anything else besides turn this model into Search mode.

W-Link Frequency

The Axio, similar to the Mammut Barryvox S, can transmit additional information on the “W-link” frequency to help keep from getting confused. W-Link frequency is essentially a separate, secondary frequency that operates on 868 MHz, the primary purpose of which is to reduces signal confusion. While this is a cool feature, it can only work with other W Link devices like the Barryvox. Unlike the older Mammut Pulse Barryvox and the newer Barryvox S, which contain the “Pulse” feature, the Axio doesn't send any movement information over the W-link frequency to help determine if the buried victim is dead or alive.

Revert To Send

The Axio is one of only a few beacons that allows the user to turn the Revert to Send feature on or off. It can be set-up to automatically switch back from Search to Send mode if it doesn't detect any motion for two, four, or eight minutes. The Axio makes four loud beeps before reverting to let the user know it is about to revert. During this time, you can press the joystick to keep it in search mode. We liked this feature but preferred the Pieps Micro and Pieps Pro's design where they continually keep beeping after reverting back to Send mode.

Novice users can use the Axio, but in practice, it is designed for more experienced backcountry users, trip leaders, or avalanche professionals who will take advantage of this model's many capabilities and functions. We think casual users will be better off with a simpler beacon like the Arva Evo5, Tracker3, Tracker S, or Black Diamond Recon BT.


The Axio is in-line with other very capable high-end beacons like the Black Diamond Guide BT and the Barryvox S. Similar to those beacons, we think this beacon is a good value for advanced users and pros who will take advance of the special functions and design features. For beginners or novice users, this beacon might be overkill, and these users may be spending more money on features and capabilities they may rarely use.


The Arva Axio is one of our new favorite avalanche beacons for pros and advanced users. It is a solid beacon for a beginner and works great for finding a single burial, but more complex situations and professional level rescue assessments are where the Axio really shines. We liked this beacon slightly more for rescue drills than the Black Diamond Guide BT because of how much easier it was to manage multiple signals, particularly if they were in close proximity.
