If you have no intention of using the BDX function, then it may be cheaper and easier to go with their regular rangefinders.
I have the non-BDX KILO2200MR model and it has served me well in both archery and rifle hunts. I think the BDX models really shine when you pair the rangefinder with one of their supported rifle optics.
Regardless of what model you go with, I think you'll be happy with Sig. Always highly rated and it performs reliably in the field. I've ranged deer out to 600 yards with no problems and non-game targets out to 2,000 yards.
