I am new to the backcountry and look forward to getting out there for the first time this season and am in the process of getting of all my safety gear and trying to get into the on snow class through friends of berthoud pass. Went to their meeting last week and when discussing beacons, they mentioned do not purchase a used beacon. Are they saying this simply to cover their ass as a liability or are their legitimate concerns with a beacon that is a year or two old? And before you ask, no my life is not worth saving a hundred bucks.
