Familiarity: I've put it through the wringer
When I'm practicing companion rescue I am always looking for all of my gear and communication to be "clean and clear" and the tracker 3 is exactly that. The compact packaging allows it to slip in and out of my pocket with ease, the leash design allows the beacon to be securely attached without restricting my movement on a fine grid search. The processor continues to blow many of the other brands out of the water (which is impressive because of all the new software that the T3 has now) allowing me to start moving towards my buried victims well before many of my colleagues or students when practicing drills. The mode button is also a sweet nod to the tracker of old but with much more sophisticated tools. The first is SS (Signal Suppression) This works just like flagging function on many other brands of beacons and is the first generation of BCA beacons to use this technology. This allows you to suppress the signal of the closest beacon, focussing on the next in a multiple burial situation.
Another function I have used and really appreciate is the BP (Big Picture) function also found under the mode button. This gives you distance and location of all victims, allowing for a more affective triage if you were to ever be faced with this terrible scenario of a multiple burial.
All and all I can't say enough about this beacon. I teach avalanche courses and am a guide and have gotten to use most beacons on the market and have to say I love my T3 because it has a perfect balance of sophisticated technology and applicable tools without the unnecessary and often unreliable bells and whistles of some other high end beacons.
