I quit snowmobiling a few years ago and no longer need my Avalanch beacon, It works with all 457 Khz beacons, The Brand is a Survival on Snow and is in great condition. If you are headed into the back country you should have one of these on you. This unit sends a signal from the minute you connect the strat and converts to a receiving unit in just a few seconds. Ther best way to contact me is by text.
