Year and a half a go I bought a Vortex Ranger 1500. Like other lazer rangefinders your results vary with ambient light and a quality reflective surface. 4 days after I bought it and used the heck out of it scouting it worked perfectly fine on a nice antelope buck at 398 yds. I looked hard at the Sig at the time also. just my 2 cts worth. MB
