Personal Locator Beacons

Technology is finding its way into the backcountry: the avalanche beacon, GPS receiver, cellphone, and personal locator beacon (PLB). The media have reported the use of personal locator beacons in dramatic and successful rescues but at least one instance of their abuse. Some experts have expressed concern that the devices will encourage over-reliance on their use.


ACR Electronics manufactures most of the units available in the United States. The devices are pricey but can be rented from PLB Rentals.

The New York Times recently published an article about PLBs.
