People get extremely defensive about their beacon selection and in truth they all do their job....... some just do it better than others.
In short, you couldn't give me a Pieps freeride. It's a slow single antenna beacon with a limited range.
The BCA tracker is touted by BCA as being better because of it's realtime bull****. Turns out it's just that. Bull****. The beacon was great when it was introduced in an era of analog counterparts but beacons have come a long way since then and the tracker is no longer up to snuff in my opinion. BTW, it's a dual antenna beacon. DSPs, Pulse's, etc are a 3 antenna.
I agree that multiple burials are an atypical situation and not a primary deciding factor in a beacon purchase, but that assumption assumes that you and your buddies have enough avy education to recognize potential slides and more importanly, stay out of the runouts. You see far too many sleds sitting at the bottom of a hill in the runout while their friends climb. Guess what that sets you up for? multiple burials........
All of the top level beacons are good choices and the performance differences are very small. Personally, I feel that a beacon should only be a beacon, leave your altimiter, thermometer, etc to something else.
Personally, I wear a DSP. It's fast, simple, and effective but so is an old school analog in the right hands
