My Holosight covers about a 3 Inch circle at 100 yards. Maybe less.... It is so easy to get on target and a lot of fun shooting.
I have impressed myself with my shooting, and I dont have the best eyesight either.
I feel like the unpowered red dot gives you less chance to make an error since you are just aiming at the center of the target and not having to wait on crosshairs to move to where you want them.
I have shot a pistol with a cheap $ 40.00 red dot and it did not compare to the Bushnell Holosight.
The holosight is "holographic" and it looks as if the dot is out on your target, or deer, and not just in the scope housing.
I hope you get a chance to try one some day, I think you will be impressed.
