Lighted nocks are a great tool to the crossbow hunter. They not only let you know if you hit an animal saving you wasted time tracking an animal you missed but couldn't find the arrow for, but also where you hit it, which is often reassuring since most shots occur during the 'golden hours' right around sunrise and sunset. They are also a great help when following a blood trail at night. It's a truly awesome feeling to be on a trail, look up and see the 'beacon' of the nock shining in the distance.
The amazing new patent pending NockTurnal lighted nock is a breakthrough design that is more affordable and lighter in weight than most other lighted nocks. The NockTurnal has a string activated linear switch that is protected deep within the nock and will not turn on or off inadvertently, it will ONLY turn on when you shoot the bolt no magnets or other things to worry about.
