Currently I have an original 93sv at the console and 93sv chirp at the bow. My concern is that I bought the chirp pretty much at launch and not long after the plus shows up. What would be the reasonable upgrade (if any) to stay at the same price point of 1K for a new unit, or stay with what I have as maybe something drastic will come out from Icast? Also, I want to get a version of panoptix eventually so maybe that will play in the future upgrade. Thanks!
