I bought a Gunwerks G7 BR2500 a year back thinking it would be just what I needed for long range shooting and hunting. With the built in weather station, inclinometer and ballistics program, it really is as easy as point and shoot and it gives you the solution to dial into the scope. I also really like that there's no need to pair it with anything else, cell phone, kestrel, whatever, just one device to get the correct firing solution, minus figuring out wind obviously. But it's just so big compared to everything else. Elk hunting with it last fall I honestly felt like I was carrying two full sized pair of binos around with me as opposed to one pair of binos and a small rangefinder in the side pocket of my bino harness like I'd prefer. So now I'm looking to see if the only other options that I know of that have built in wether stations and ballistic programs where you can actually enter your own ballistic are maybe the right choice for me, the Sig kilo 2400 or the Leica 3500.com or 2800.com. I hear good things about the Sig other than it doesn't pick up soft targets well, does it have to be paired with a phone or can it be used to get a firing solution by itself? I don't know much about the Leica, are people finding this rangefinder is accurate in giving correct come ups in reference to angles, altitude and your own custom ballistics? Any help would be appreciate, thanks, Shawn.
