+1 for the sig kilo. The lowest range version is a black crosshair though I think. The 1600 I have is red cross hair and I’ve ranged out to 900 with it in sunny conditions.
Big fan of the ballistics system paired with the phone app. You get a readout on the rangefinder with the amount to dial. Can go from spotting something to dialed and ready to shoot very quickly. App is easy to use, very intuitive.
