With all of this talk about classes and the 20+ beacons on the market. I find it hard, even for someone in the outdoor industry, to find conclusive findings on beacon preferences. In my search I found a lot of people use the Tracker 2 and I've had some friends swear by the Pieps Sport. Does anyone have some good insight to the use of both? Owned both? Or just one of them? What are your thoughts?
