No there isn’t an app yet (that we know of anyway) for avalanche rescue, but the iProbe isn’t an iPhone accessory. It is actually a sensor-equipped probe and transmitter.. The iProbe ONE from Pieps features a sensor in the tip that can emit an audible signal in the handle when it gets within two meters of a buried transponder. It operates on the EN300718 standard signal for emergencies.
This could help rescuers narrow down where to dig, which can be crucial when it comes to finding trapped skiers or hikers.
