The BR4 has onboard solutions as well and will give a solution as far as it will range - which is far. It's ranging performance is impressive and optimized for game/soft targets so you'll get ranging much further with this one on an animal than you'll get with other brands. Extremely fast computations and very accurate solutions factoring in environmental/earth effects. You'll be impressed. Spend time with it and the function will become of part of you. Good luck.I just went down this road. I went with the Sig5k. Ranges out to distances I have no business shooting game at. Also has ONBOARD ballistic solutions out to 800 yards using AppliedBallistics/Sig software. It's worth a hard look as it can be had for $500-600. The 5k is just a smaller version of the 8k which for most of us is all we need. I've programmed 5 of my rifles into it and it's spot on. Has onboard real-time environmental info also.
