AutoWhistle™ Tree Well Alarm

The AutoWhistle™ Tree Well Alarm is a first-of-its-kind, patent-pending alarm system that automatically detects if you get trapped in a tree well and alerts others that you need help - without any input from the user required. The AutoWhistle™ utilizes a 100+ dB S.O.S. alarm - similar in volume to a jackhammer - which is tuned to travel long distances through snow, effectively alerting others that you need help.

With no professional training required - and a much lower cost than other avalanche equipment - the AutoWhistle™ integrates seamlessly into your existing gear, fitting perfectly in the pocket of your outer jacket, and is suitable for beginners and experts, adults and children alike.

Because 90% of tree well incidents involve being flipped upside down, prohibiting self-rescue [Source: Wilderness Medicine Magazine], the alarm can detect the vast majority of tree well incidents, especially those that are most likely to be fatal.

The AutoWhistle™ can also be used as an emergency battery backup, providing power to cell phones, satellite phones, rechargeable headlamps, and other safety equipment.
