I don't think it's available yet. At least at the last time I checked my Liberty Mountain account.
I had several friends check it out at SIA last year. Their words where that it looked like a "game changer". Take that for what it's worth because obviously there was no field work with it. If and it's a big "if" it comes out this season, I should be able to get my hands on a demo. I'll post my thoughts. I need to do this with the 3+ too. The biggest thing is that there isn't any snow, hopefully it'll get started here shortly. Otherwise, we'll be doing beacon searches in piles of leaves at the local park.
