Very easy to setup, best and brightest aiming device without batteries. Once you chrono your speed, just adjust to the number on the calibaration chart. Only thing I would suggest them to do is to add micro adjust verses adjusting set screw for windage. Overall excellent, craftmanship.
My FPS on my Z7 extreme tactical is 276 fps so I get zero yards out to 65 yards very accurately I mean dead on I'm impressd.
Plenty of clearance for my T5 quiver.
Worth every dime.
PS. I shoot different Gold tip arrows (Velocity, and regular). I already no my numbers for both so all I have to do is adjust and I am ready to go no more tape.
Pros: fiber optics, accudial(verses tape)
Cons: would like to see miroadjust option.
