I would not rely on a blue tooth connection while hunting. Murphy will rear his ugly head when you need that connection. For a long time I ran a range finder (no bluetooth), and a Kestrel 5700 AB Link, with paper backup. Kestrel 5700 AB is an awesome piece of equipment. Once your load’s ballistic curve is confirmed / trued it is incredibly reliable. My workflow is laser my target and punch the distance into Kestrel, capture target direction and wind direction and speed at my location and either write down dope if multiple targets or dial / hold and engage if a single target like an animal. Now 3 years ago I went on an elk hunt with a buddy. My elk was at 480 and his 523. We had plenty of time with his Elk as he was making his way across the side of a mountain. My elk was at the top of a ridge and the guide was fearful he’d go over the top if I didn’t shoot. In this situation I felt like my LRF / Kestrel combo was slow and I felt rushed. If I had to rely on a Bluetooth connection and it failed, it would have been worse. All that to say I think a Bino LRF w/ ballistic solver is the way to go. It’s faster, and if you still want to connect to your kestrel (kestrel will give you better atmospherics than the Bino), but connection fails you still have a solution in your binos. If you don’t want to spring for $2500+ Bino / LRF / Solver (Sig Kilo10K, Revic BLR10b, Vectronix, Leica, Swaro etc.) look at the Vortex Fury 5000AB. It has AB elite on board, will Bluetooth to a Kestrel and can be had for $1000-$1200. Hope this helps.
