I agree with the sig 2200. I bought one from cabelas for the same price that B23 did. I have used it on deer, coyotes, prairie dogs, etc and it has never missed a beat. No problems ranging out to 1000 or a bit over on animals. I like it because it is small which doesn’t make much clutter when you are wearing it and harnessed binos while bow hunting. For prairie dogs, I found a guy that 3D prints tripod mounts for them which helps greatly when ranging mounds out to 1000
