The Best Avalanche Beacons of 2025

The Mammut Barryvox ($299) is a fully fledged avalanche beacon at a great price. For your money, nothing else on the market beats it.

The Mammut Barryvox has an advertised search range of 70 m. In our testing, this was accurate. However, the sensitivity of this and every beacon in our test when used a proper distance from sources of EMI (such as a phone, radio, satellite communication devices, and even something like car keys or heated gloves) is crucial.

Because of the sensitivity, it’s easy to pick up phantom signals or even see incorrect distance and direction indicators. Every beacon we reviewed is susceptible to this. (Please read the FAQ for more details.)

A vital point for the Mammut Barryvox is the user interface. It has an easy-to-see screen, a confidence-inspiring mode slider with a lock, and icons and onscreen directions that are easy to understand. For example, if the arrows take you one way but your numbers are climbing, it will tell you to turn around with a U-turn icon. As you get closer, the screen shows when you should be bracketing in the fine search.

The Mammut is very tenacious on a signal when it’s locked on, something called signal drag. To the point where you can twirl the beacon around, and you won’t lose the signal or swap to another signal as many other beacons will. This is both a good thing and a bad thing.

The good: no matter how sloppy the rescuers’ technique is, they will probably have a successful time finding the beacon, as it’s hard to lose a signal once you have it. The bad: when you have multiple beacons in play, especially near each other, proven techniques like three-circle or micro search strips may not work as quickly as on other beacons due to this signal drag.

Also, when doing trailhead checks, the signal drag makes it very tough to make sure partners close to each other are all sending a signal. This is easily fixed by just using the group check mode, but anyone looking at this beacon should be aware of this beacon’s tendency to get locked on and stay on.

Fortunately, flagging works well on this beacon, making it easy and speedy when practicing multiple burial scenarios. With its long range and excellent user interface, the Mammut Barryvox is a great beacon for anyone looking to upgrade an older beacon or someone new to the backcountry world.

The Pieps Pro IPS ($530) is a professional-grade tool for guides, educators, and professional search and rescue personnel. Using its expertise, Pieps built one of the most advanced beacons on the market.

The design of the Pro IPS is unique. For instance, to start searching, you engage a swing-out antenna, which isn’t a feature commonly found on transceivers. Interestingly, this isn’t Pieps’s first use of this design.

The Pieps Vector had a similar swing-out antenna, but a host of technical issues forced it out of production. Fortunately, they got it all right this time, and we love the design. Compared to the slider switch Pieps often uses, the antenna is simpler and faster to use, even with thick gloves on. The feel and finish are top-notch all around. The scan button can be tricky to push, but overall, it’s a great design.

The screen is relatively large and easy to read with a nice backlight. While the user interface doesn’t have the advanced guidance assistance that the Mammut Barryvox does, many professionals will likely prefer the straightforward presentation of the Pieps.

The Pro IPS headline feature is the Interference Protection System, which detects and compensates for electronic interference when transmitting a signal. It’s recommended to always keep any electronic devices 20cm/8in away from your transmitting beacon.

The Pieps goes one step further and attempts to maximize the signal it is sending when inference is present. During the search phase, the Pro IPS recognizes sources of interference and, depending on the magnitude, will recommend different search strip widths to overcome them.

The other prominent technical feature is the Dual Antenna Signal Processing, which allows extremely fast processing on the x and y antennas. In testing, we noticed that even with unfavorable coupling positions, the Pieps could always pick up a stable signal at long distances. Throughout all search scenarios, the beacon seemed to be moving at lightning speed. It rarely had hiccups, even in complex multiple burials.

The Pieps Pro IPS is Bluetooth enabled, and the companion app allows you to change or enable a nice spread of special features, including a device diagnostic check, group checks with standard and pro modes, and scan mode with regular and detailed options. The scan mode shows the number of beacons buried in different distance intervals, allowing for an assessment of rough locations to allocate rescue resources in a multi-burial situation.

The detailed scan mode goes one step further and allows for scrolling through different signals. Auto revert to send is available if the rescuer is buried in a secondary avalanche. You can also easily update firmware via the app.

Our only two gripes (and we’re really reaching) are that the harness is short and that sometimes people find the buttons tough to push. Since we typically keep our beacon in a pocket, the harness is a non-issue for us, but we know some people love it. The button issue is easily solved by using a little more force and intention.

The Pieps Pro IPS packs a lot of technology into a competent package. We were consistently impressed with this beacon in all phases of the beacon search. Long-range signal acquisition rarely picks up ghost signals. The interference protection the beacon offers when you’re sending a signal is unmatched. And a great suite of special features is sure to suit any user.

Rounding out all of these capabilities is a rugged case and the simple but effective swing-out antennae used to switch from send to search mode. This Pieps Pro IPS beacon will appeal to professional users and recreationalists who want one of the best beacons on the market.

Note: In November 2024, before we added the Pieps Pro IPS to the guide, Pieps issued a recall for these beacons. They dealt with the issue quickly and efficiently, and we had no trouble with ours. We inspected the battery contacts, the source of the problem in other units, and it was apparent they fixed it.

The Ortovox Diract Voice ($450) is a premium avalanche beacon that comes with a unique feature among avalanche beacons: it talks! Ortovox is a company known for very thoughtful design in all its products, and using this beacon you have to be impressed with how nice it feels in hand.

The standout feature of this beacon is voice guidance, which can be turned off in the companion app (there is also the Diract without voice assistance). Testers found the voice guidance to be useful, particularly if we were in a real rescue situation where we would be very stressed and not thinking as clearly.

For instance, if you are following a flux line and getting farther away, the Diract Voice will tell you to “Turn Around!” Simple, but effective in correcting a mistake — following a signal the long way around — that is often made by backcountry users who are learning about beacons or those who don’t practice enough.

From a distance, the voice guidance works well and is helpful for a less practiced individual. As you get closer to the beacon you are looking for, the guidance is more limited, and many testers found it almost distracting rather than helpful. There is so much potential here; well done, Ortovox, for the innovation!

Without voice guidance, this is still a great beacon with two potential caveats. First, it has a noticeably shorter range than any other beacon we tested. It’s still well within the minimum search strip width of 40 m that many avalanche courses will use, but when some other beacons have nearly double the range, it’s noticeable.

The other noticeable difference is the Diract Voice uses a rechargeable lithium-ion battery versus replaceable batteries. In testing, the Ortovox lasted similar lengths of time between charges as any other beacon with AAA batteries.

If you forget to charge your battery, you run the risk of being out of battery and not going skiing or going with a battery without enough charge in it to safely do a rescue. Remember, your beacon will use significantly more power in search than in the send/transmit mode.

Using the beacon without voice guidance, it processes single and multiple burial scenarios very well. The design of the beacon is well thought out, making it easy to swap between modes with gloves on.

The Ortovox Diract Voice has a lot going for it. For newer backcountry users, voice guidance could work really well to help a rescuer in a very stressful situation. We’re very excited to see where voice guidance technology in beacons can go moving forward.

The Black Diamond Guide BT ($500) avalanche beacon is a professional-level beacon with a wide range, excellent performance in single and multiple burial scenarios, and a comprehensive suite of unique features.

While it doesn’t quite have the extended range of the Arva or Mammut beacons we also tested, the Guide BT is fast and sure in processing signals. During the search phase, this beacon provides some haptic feedback with vibrations when it acquires a signal. This is a nice bonus to the straightforward, mostly easy-to-understand user interface. The screen is small and sometimes harder to read with polarized sunglasses.

The Guide BT has a group check mode, though it is a bit quirky in that you must continuously hold down the flag button. If you don’t, it reverts to send mode. This wouldn’t be an issue, except the button is a little tough to hold down, especially with gloves on.

The scan mode is an advanced function enabled while searching via the button next to the flag button that can be useful when you have multiple burials. When enabled, it shows the total number of victims within 5 m, then 20 m, and then 60 m. Practiced users will be able to get a better sense of victims’ locations within the debris field and deploy resources accordingly.

Black Diamond has had a history with a predecessor of this beacon and the DSP Sport, with mode selection sliders not staying put and potentially turning the unit off when slid into the harness. This beacon, along with the Recon X, has redesigned and beefed up sliders that certainly seem to have fixed the issue.

In making it stronger, it’s now a little more difficult to use, especially with thicker gloves on. In direct comparison to how other companies toggle modes, the slider design is certainly our least favorite design choice.

Beyond the ergonomics issues of the slider and small screen, we found this beacon to be incredibly powerful during testing. Recreationalists who would like to go with the Black Diamond beacons are better served by saving a few dollars and going with the Recon X, where you don’t give up too much.

For professionals and advanced recreationalists who like great performance and can work with the design of the beacon, the Black Diamond Guide BT is an ideal choice.

The Backcountry Access Tracker S ($299) is BCA’s entry-level avalanche beacon. The 2025 version features an improved case design from the previous Tracker S but keeps the same internals.

Having used the previous version, the new casing immediately stands out. We like how easy this beacon is to use with gloves on, especially when pushing the options button. Overall, it feels a little nicer in the hand than even the higher-end Tracker 4. Shoutout to the very obvious locking steps on each mode on the mode selector. Everything feels very sturdy and well thought out.

The Tracker S is a very solid entry-level beacon. It performs admirably in single burial searches, with middle-of-the-pack range and processing power. The recommended search strip width of 55 m means you can quickly work an avalanche scene by covering a good amount of ground to find a signal.

The Tracker S can be a little less easy to work with than some other beacons. Being fully aware of what your beacon can do and its special features is important for every beacon out there, of course. But BCA’s usage of a smaller and less advanced screen on the Tracker S means that some information comes in the form of icons and abbreviations that might not be perfectly clear. The Tracker S is designed to be a super simple product, so you can certainly make the argument it doesn’t do more than it needs to.

For special features, the Tracker S can temporarily mask a signal when searching for multiple beacons in the signal suppression mode. This will tell the beacon to ignore the strongest signal it detects (usually the closest one) for 60 seconds while you search for the next strongest signal.

Other beacons on the market do not have the time limit the BCA does. In practice scenarios, signal suppression is functional but can feel confusing and less intuitive than other beacons that use a flagging feature without a time limit. Practice can help with this! And importantly, statistically speaking, most avalanche rescues a recreational adventurer would respond to will be a single burial rescue anyway.

The Tracker S also includes BCA’s big picture mode, which temporarily cycles through all the signals the beacon picks up, including distance and direction. This allows rescuers to get an overall view of the rescue field and how they might deploy resources.

The Tracker S lacks some other features that would be nice to have but aren’t deal breakers, including group check and updatable firmware. It has an auto revert to send mode in case searchers are buried by a second avalanche. However, instead of being tied to an accelerometer to detect motion, it is on a five-minute timer. It also must be turned on every time you turn on the beacon.

The BCA Tracker S combines a wonderful exterior with a simple user interface to make a beacon easy and reliable for most people. For the price, especially when found in rescue bundles that come with a shovel and a probe, this is a great beacon for most recreational users, especially those just starting out.

The Black Diamond Recon X ($350) is a more streamlined version of the company’s professional-level Guide BT beacon. While you lose some advanced features, you still get the blazing-fast processor that performs awesomely in single and multiple burial scenarios. It also has some bonus features like group checks and the ability to use lithium or alkaline batteries.

This beacon, in practical use, doesn’t quite have the range of the Arva or Mammut beacons, but it sure is close enough not to be a huge deal. Once the Recon X has a signal, it will guide you with a simple user interface of arrows and distance. Like the Guide BT, the screen can sometimes be harder to see if you use polarized sunglasses, and it feels small.

In testing, we did feel the Black Diamond beacons did really well in the fine search when rescuers were in the critical 5 m range. There is no metric to point to for it being any faster; it was just the impression that the processor was very fast and was harder to overrun like some other units.

For special features, you still have flagging and a group check mode. The Recon X flag button is larger than the Guide BT, and we had an easier time holding that button to use group check mode. We wish you did not have to hold it down the entire time during the group check, though.

Black Diamond has a history with the predecessor of this beacon, the DSP Sport. Its mode selection sliders did not stay put and could potentially turn the unit off when slid into the harness. Its redesigned and beefed-up slider certainly seems to have fixed the issue. However, by making it stronger, it’s now a little more difficult to use, especially when wearing thicker gloves.

Beyond the ergonomics issues of the slider and a smaller screen with some older feeling user interface icons, this beacon shone for his power and performance during testing. If you are looking for your first beacon or replacing an older beacon, the Black Diamond Recon X is a great choice if you can work with the ergonomics.

It’s a much easier beacon to find in the U.S. than our best pick (the Arva EVO BT), and it usually comes in a package with a shovel and probe. For professional or advanced recreationalists, you might like the Guide BT more.

The Backcountry Access Tracker 4 ($399) is BCA’s flagship avalanche beacon, featuring a sturdy case with glove-friendly buttons and a simple and reliable interface. BCA beacons are ubiquitous in avalanche courses and guide operations and are found in the gear closets of many recreational backcountry skiers and riders in the United States. They aren’t flashy, nor do they have the longest range or the coolest special features, but they do the job for which they were designed: avalanche rescue.

During testing, the Tracker 4 never really stood out in any way when directly compared to other beacons, but it also doesn’t have many glaring shortcomings either. In single burial scenarios, the Tracker 4 performed well, with a recommended search strip width of 50 m. Once it acquires a signal, the processor is fast and accurate, bringing you within range quickly.

The simple two-digit display does the job of giving you direction and distance. You must absolutely learn the details about what the different two-letter designations and multiple burial icons mean in the context of a rescue situation, as it’s not always obvious what is going on.

The Tracker 4 isn’t as great in multiple burial situations as other beacons we tested. Signal suppression works by being close to a transmitting beacon and hitting the suppression button, which temporarily masks the closest signal and gives you directions to the next closest signal.

This is done to ensure that a rescuer is not masking the incorrect signal. In practice scenarios, signal suppression is functional but does feel confusing and not as intuitive as other beacons that use a flagging feature.

The Tracker 4 has another mode called big picture, which cycles through all beacons transmitting within range and their rough distance and direction. This can give a good picture of the situation and how to go about deploying rescue resources. However, it requires practice to fully grasp what the display is telling you about the situation.

The BCA Tracker 4 combines a rugged case with a simple user interface to make a beacon that is easy and reliable to use for most people.
