zoltan korossywrote a review of Backcountry Access Tracker 2 Avalanche Beacon on March 22, 2010
An excellent beacon which carries on the tradition of the Tracker DTS. It's an extremely simple beacon to use, which even a first time user would be able to carry out a search with. It has one switch, one toggle, and one button. It our looking for something which requires minimal setup or study to use, this is it. There's also a lot to be said for an easy and foolproof device when faced with a high adrenaline situation. It's pretty hard to use incorrectly. BCA has also done the right thing in keeping the price low, and making a three antenna beacon affordable for more people. It eliminates spikes as effectively as any 3 antenna model.
You should note, though, the Tracker 2 doesn't have a multiple burial search capability, nor can it mask a beacon you've already found. It uses the same search restriction method which the Tracker DTS used, which requires knowledge and practice of the method. I can see why they've done it, since only about 2% burials have multiples victims, and it keeps the beacon extremely simple, and it says in line with the design philosophy.
The Tracker 2 slots in nicely with the other three antenna receivers. If you want extremely high tech with a lot of options, look at the Barryvox Pulse or Ortovox S1, if you want a simple beacon with multiple burial capability look at the Pieps DSP, and if you want a inexpensive and barebones simple beacon look at the Tracker 2.
