Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


An intuitive transceiver that's simple and efficient to use. Mammut’s redesign of the Barryvox (a leading industry beacon for almost 10 years) focused on instinctive use in a highly stressful emergency. Antennas and processors allow a 70m-wide search strip. Quick and accurate arrow direction quickly gets you where you need to be. A better screen, marking and unmarking capabilities, analogue mode and advanced search settings make this pro model ideal for ski guides, ski patrollers and heavy users who use various search methods.
