This one is not like the burris, you range with your sig laser and it tells the sig scope the yardage and puts a dot for you to aim with. So its two pieces to shoot with.
So a few takes on this. If you shoot 300 yards max and under its worthless. Past that i can see its use as long as the sig laser is calculating angle, temp, direction, alt and sending all that to the scope.
The hole in the tech is windage. From what i see you still have to dial wind somehow? The redicle has no lines for hold off and as someone who shoots long a lot, wind is my only problem not drop. So even with this if you take a 900yard shot on a average day its still a miss. Use your balistic calc to see what wind does. Blow it by a few mph, say 5mph when its 8 and you just missed.
