Gear Review: Mammut Pulse Barryvox Transceiver

This Mammut transceiver has three antennae and an internal compass.

This powerful beacon minimizes search time thanks to three antennae and an internal compass that pinpoints buried victims within a 50-meter range. Headed off course from one of your victims? The direction indicator alerts you. Other notable features: If multiple people are buried, the Pulse lets you mark each victim as you find them, then search for the next. If the victims are also wearing a Pulse, this beacon will detect their movements, including heartbeat and breathing, which can aid decision-making in a mass-casualty incident. And it signals loudly, then reverts to send mode after eight minutes of non-use in search mode.

(Translation: You’ll be transmitting if you’re caught in a secondary slide.) The two-button operation is intuitive for basic searches, but requires practice for using advanced functions; as with all beacons, do some dry runs before you hit the backcountry. $450; 11 oz. (with chest strap). Great deal alert: For an extra $30, you can upgrade to the Alugator Light package, which includes a Pulse beacon, a 240cm probe (8 oz. with case), and the Alugator Light metal shovel (1 lb. 4 oz.);
