Got a New Toy
ATN X-Site 4k Pro. Day/Night digital night vision scope. Of special interest to me is its built in ballistics calculator that will move my reticle to the correct point of impact for targets based on range. Airguns only shoot flat to about 65 yards then they start to drop dramatically. It works by first taking my ballistics data for my airgun (.308 97 grain bullet, 900fps muzzle velocity, .177 BC, 50 yard zero) and then ranging my target by either measuring the top and bottom of my target against a pre-set target height (I'm using the shoulder height of a deer) or by using an optional laser range finder that connects to the scope. The range finder is another $300 and adds nearly a pound to the weight of the scope, so I opted to just use the built in range estimator.
I did find that for the range estimator to be accurate I have to lie to it. It looks like the calculation algorithm is off. I found that for the scope to correctly range a 3' tall target, you have to tell the scope the target is 1.3' instead of 3'. Then it will calculate the ranges with some degree of accuracy. If you use the true target height, it will add 100 yards or more to the estimated range.
Daytime picture is full color and very clear.
