Hi- I'm not very knowledgable about these beaons/trackers? i would like to get one for my son as he is planning to do some back country skiing again in BC, how do they work?
This tracker is the industry standard for beacons. Most cat/heli operations use these. In essence, when the beacon is in transmit mode, it sends a signal as to its location. Each beacon can also be switched to "search" mode to look for other beacons that are in the transmit mode. They're useful in that, if you have 2 or more people backcountry skiing, it enables one to search for the other if he/she is taken down in an avalanche and buried. They are absolutely essential to backcountry skiing.
BCA has a very good link for education on their website here:
They also have a good facebook channel that teaches you how to search, dig and probe properly here:
