I've use lumenocks on my Parker crossbow for years. The only real difference I notice is that the arrows with the lighted nocks is they drop slightly more at a given distance. Like for my 30 yd pin/mark on the scope if the normal nock is dead on, the lighted nock hits 1/2" low. I assume this is because the very small gap between the nock and the bolt shaft that is needed to keep the nock turned off until the arrow is shot.
You can't bag a big one if your not out tryin
