The Best Avalanche Beacons: 4 Compared (and One to Skip)

RBE top pick

Mammut Barryvox 2

See why it wins Find it on Amazon Compare all

The Barryvox 2 pairs a stated 70 m range with guided search support, a continuous self-test and an included carrying system. The Tracker 3+ is the value pick: simpler display, proven layout, assembled and tested in the USA.

A beacon is the piece of avalanche kit you hope to never use for real, and the one you are most likely to fumble when it counts. Every transceiver here transmits on the standard 457 kHz frequency and has three antennas, but they differ in published search strip width, how they handle multiple burials, and how forgiving they are for someone who practices twice a season. We compared a mainstream pick, a budget standby, a pro-spec model and the industry's voice-guided experiment, using each maker's published specifications and owner reports.

RBE top pick

Mammut

Mammut Barryvox 2

Buy it

The compact all-rounder with a stated 70 m range and guided search support.

Best for: Most backcountry skiers and snowboarders who want fast, supported search behavior without a pro-level feature stack.

$$ · mid-range

Why we like it

• Digital 3-antenna transceiver with a stated 70 m range and a self-test that runs at power-on and continues in the background while transmitting.
• Runs on two AAA alkaline batteries, included in the box, with a claimed send time of around 450 hours.
• The Barryvox carrying system is included in delivery, and the Barryvox app handles firmware updates, settings and search training over Bluetooth.

Know before buying

• Mammut publishes a range figure but not a separate search strip width, and does not publish the device weight; only the 115 x 68 x 21 mm body dimensions are listed.
• Mammut specifies alkaline cells only, so in deep cold you give up the extra send time lithium cells can buy on beacons that allow them.
• The guided fine search rewards a deliberate pace; rushing it is the habit instructors spend the most time correcting anyway.

Backcountry Access

BCA Tracker 3+

Buy it

The long-running value beacon: instant real-time distance display, signal suppression for multiple burials, assembled in the USA.

Best for: Newer backcountry travelers and anyone who wants a simple, budget-tier beacon to practice with.

$ · budget

Why we like it

• Three antennas with a stated 50 m maximum range and a 55 m search strip width.
• Runs on three AAA alkaline cells, rated at roughly 250 hours in transmit and at least 1 hour of search after 200 hours of transmit.
• Signal Suppression and Big Picture modes handle multiple burials in a deliberately simple way, and motion-sensing auto-revert switches back to transmit if you stop moving.

Know before buying

• The 55 m strip is narrower than the 70 and 80 m figures Mammut and Pieps publish, so your search pattern has to be a little tighter.
• No Bluetooth and no app; BCA lists the software as upgradeable, but updates go through BCA rather than your phone.
• The LED display is fast but shows less information than the graphic screens on some other beacons here.

Pieps

Pieps Pro IPS

It depends

The widest search strip in this comparison at 80 m, with interference-shielding tech aimed at professionals.

Best for: Guides, ski patrol and motivated tourers who will actually use Scan mode and the pro feature set.

$$$ · premium

Why we like it

• A stated 80 m search strip width and 70 m maximum range, the widest in this comparison, with 3 antennas and Dual Antenna Signal Processing.
• Runs on three AAA cells with a rated minimum of 600 hours on alkaline and 800 hours on lithium, the longest battery life here.
• Bluetooth plus the Pieps app for updates and settings, plus pro features: Scan mode, Group Check Pro mode, an inclinometer and Interference Protection System on the transmit side.

Know before buying

• The heaviest published weight here at 212 g with batteries, in a 120 x 75 x 24 mm body, and the premium tier price.
• The feature depth that attracts professionals is wasted complexity for the one-rescue scenario most users will ever face.
• Firmware 1.3 is the current version; the beacon expects periodic updates and a bit of systems administration on your part.

We'd skip it

Ortovox

Ortovox Diract Voice

Skip it

The first avalanche beacon with spoken voice navigation, now listed as not available online by Ortovox as a newer voice model takes over.

Best for: Hard to recommend while it is being phased out: beginners drawn to the voice prompts are better served by a current model and practice.

$$ · mid-range

Why we like it

• Three antennas with Smart-Antenna technology, which picks the best-positioned antenna to transmit in a burial, plus a Recco reflector in the carrying system.
• A waterproof shell (EN 300718), a full-graphic display, Bluetooth updates through the Ortovox app and a rechargeable low-temperature lithium-ion battery; no AAA cells to buy.
• Made in Germany with a 5-year warranty on registration, and spoken instructions for every phase of the search.

Know before buying

• Ortovox lists the Diract Voice as not available online and is promoting its new FOCUS Voice transceiver, so this is an outgoing model.
• A rechargeable battery means the beacon can be flat when you grab it, where alkaline beacons sit ready for a season on fresh cells.
• The 50 m maximum search strip is the narrowest of the four, at the same price tier as the Barryvox 2.

How we judged the field

Five things decide whether a beacon earns its place in your pack: how wide a strip it searches, how fast and readable its display is when you are moving, how it handles more than one burial, what powers it, and how much training it assumes. Range numbers come from manufacturers that each measure differently, so we treated them as ballparks and weighted interface and published strip width more heavily.

The field is now mostly three-antenna digital transceivers on the same 457 kHz standard. We picked a mid-range all-rounder, the long-standing budget favorite, a flagship aimed at professionals, and the one voice-guided beacon in the market, then compared each maker’s published specs against what owners report.

The Barryvox 2 is the beacon most backcountry users should buy. Mammut builds it around three antennas, a stated 70 m range and a self-test that runs at power-on and keeps checking transmit and battery function in the background. In search it gives acoustic guidance and a visual interface that walks you through the search phases, and it can mark buried subjects in a multiple burial. It runs on two AAA alkaline batteries, included in the box and rated around 450 hours in send mode, and firmware updates arrive over Bluetooth through the Barryvox app rather than a service visit. The carrying system is included in delivery, so there is nothing extra to buy before the first tour.

The trade-offs are modest. Mammut publishes a range figure rather than a search strip width, and it does not publish a device weight, which makes a like-for-like comparison with the Pieps and Ortovox harder than it should be. The maker specifies alkaline cells only. The guided fine search works best at a deliberate pace, which mostly punishes the bad habit of moving too fast. Those are footnotes next to a fast, supported search interface at a mid-range price.

The Tracker 3+ is the old dependable of the category: three antennas, a stated 50 m maximum range and a 55 m search strip width, and a real-time distance display that has not changed much because it did not need to. It runs on three AAA alkaline cells rated at about 250 hours of transmit, and its Signal Suppression and Big Picture modes handle multiple burials with simple, learnable logic. Motion-sensing auto-revert flips it back to transmit if a second slide catches you. BCA lists it at 164 g without the 120 g harness.

Its limits are real but livable. The 55 m strip is narrower than the figures Mammut and Pieps publish, so your search pattern has to be a little tighter. There is no app and no Bluetooth; BCA calls the software upgradeable, but updates run through BCA rather than your phone, and the LED display shows less than the graphic screens on some of the others. What you get instead is a simple, instantaneous real-time display, assembled and tested in the USA, at a budget tier.

The Pro IPS is the widest searcher here: a stated 80 m search strip and 70 m maximum range, Dual Antenna Signal Processing, and Pieps’s Interference Protection System, which the maker says compensates for electronic and metallic interference on the transmit side so a buried user keeps full transmit power. Battery life is the best in the group at a rated minimum of 600 hours on alkaline and 800 on lithium. Around that core, Pieps stacks professional tools: a Scan mode that surveys the whole deposition zone, Group Check Pro mode, an inclinometer, Auto Search-to-Send, and Bluetooth updates through the Pieps app. Firmware 1.3 is current.

Whether all of that helps depends on who you are. The feature set is aimed at guides and rescuers managing complex scenarios; in the far more common single-burial search it adds menu depth and cost, and at 212 g with batteries in a 120 x 75 x 24 mm body it is the heaviest beacon with a published weight here. If you instruct, guide or simply want the deepest tool, it is the pick. If you are a recreational tourer, the premium buys complexity you will never open.

The Diract Voice was the industry’s experiment: the first beacon that talks to you during a search. Ortovox gives it three antennas with Smart-Antenna transmit switching, a waterproof shell rated to EN 300718, a full-graphic 34 x 45 mm display, a maximum 50 m search strip, flagging for up to four victims, a Recco reflector in the carrying system and a rechargeable low-temperature lithium-ion battery, then adds spoken instructions that walk you through each phase. It weighs 210 g plus 80 g for the carrying system, is made in Germany and carries a 5-year warranty on registration.

The reason to skip it is timing. Ortovox’s own product page lists the Diract Voice as not available online and promotes its new FOCUS Voice transceiver, so you would be buying an outgoing model at the tail of its life, with the firmware support questions that implies. On the spec sheet it also has the narrowest published strip of the four at 50 m, and the rechargeable battery is the other compromise: it can be flat when you grab the pack in November, while an alkaline beacon sits ready for a season. Voice prompts are a reasonable idea for anxious beginners, but at the same price tier as the Barryvox 2 you get less strip width and a model on its way out. Buy a current beacon and spend the difference on an avalanche course.

Mammut Barryvox 2 vs BCA Tracker 3+: which should you buy?

Both are proven three-antenna transceivers, and the choice mostly comes down to interface and money. The Barryvox 2 gives you a wider published range figure, a visual interface with guided steps, Bluetooth updates from your phone and an included carrying system. The Tracker 3+ counters with a simpler display, a 55 m strip, and a lower price for the same fundamental job.

If you are new, on a budget, or buying a second beacon for a partner, the Tracker 3+ is the sensible buy. If you want the more supportive interface and longer rated battery life, and will keep it updated, buy the Barryvox 2.

What to look for

• Three antennas: the baseline for modern transceivers; all four here qualify.
• Search strip width: wider strips cover more ground per pass; 70 to 80 m figures beat 50 m, with the caveat that each maker measures its own.
• Interface clarity under stress: a display you can read fast matters more than buried feature menus.
• Battery system: AAA alkaline for set-and-forget seasons, lithium where the maker allows it for cold endurance, rechargeable only if you will actually charge it.
• Multiple-burial tools: marking, signal suppression or scanning modes, by how you will actually practice.
• Updates: Bluetooth or maker updates keep firmware current; check what the brand supports and whether the model is still current.

Our final take

For most people heading outside the boundary, the Mammut Barryvox 2 is the right beacon: a stated 70 m range, guided search support and the carrying system in the box. The BCA Tracker 3+ earns the value slot with a simpler display at a lower tier. Guides and gear-forward tourers can justify the Pieps Pro IPS’s extra strip width and pro modes. The Ortovox Diract Voice is the one to skip: it is an outgoing model the maker no longer sells online, with the narrowest published strip here and a rechargeable battery that adds a failure point AAA beacons do not have. Whatever you buy, the beacon is only the start; a probe, a shovel, a course and regular practice do the rest.
