Exactly, for the benefit of others I will state for the 4th time that PLB batteries only last for 1-3 days when transmitting.Originally Posted by rockin rex
One device that hasn't been mentioned is the RECCO rescue system. Which is really good for recoveries. It's just a passive chip that reflects radar signals, and it never runs out of batteries.
Regular avalanche beacons would be totally useless in this case. Their signals are only detectable within a few hundred feet and the batteries can only transmit for a few days, at the most.
