The Lumizone is designed from the ground up as a crossbow scope. The turrets are 1/2" c;icks at 20 yards. The distance between yardage settings is adjustable(by magnification). This is important. This is where all other multiline scopes fall down. Why remember 15, 32, 47, etc. when it can always be 10, 20, 30, 40, 50. It also has a handy speed indicator from 250 - 350 fps for doing this. I would suppose arrow construction might also affect where to set this. Magnification is fairly low like 1x - 4x depending on speed. Also, the instructions say that the windage triangle is good for a walking deer at 20 yards. The overall lens, reticle, etc. quality is a hair lower than I like, but this has had no impact on function and the price is right. It is made in China which is frustrating. The illumination is really a feature you might rethink. Accidentally setting high illumination at first light could blow your shot as the light bleeds quite a bit. I don't normally use illuminated crasshairs, but I chose them this time. If money were at all a factor, I think the Varizone would be as good or better of a scope. So as a crossbow scope, I would say 5 stars.
