Lighted nocks are a terrific hunting aid because they allow an archer to see the impact of a high-speed arrow from a crossbow or swift compound. During practice, they make shooting more fun and can show the impact of an arrow at more extended range. Finding an arrow after a shot just before dark can be critical for determining wait time before trailing. Lighted nocks are especially helpful to crossbow hunters since arrow speeds are so high and finding an arrow without the light enhancement is very difficult.
For all of the benefits of lighted nocks, one universal knock, pun intended, is turning the darned things off. People use pliers, pocket knives, teeth, and other means to prolong battery life and turn off the nock. Here’s a short YouTube video explaining how to turn them off.
