What is an arrow nock? The arrow nock is the simple but critical part of the arrow. It is the fork-like part that comes into contact with the bowstring, serving as the direct conduit? between the energy stored in the bow and the arrow as the deliverer of that energy. Think of it as the sole engine placed in the rear of a jet fighter. The fighter flys in the direction that the engine is pointed at, and the same principal applies to arrows.
And this is where things start to get difficult.
It all lies in the fit
Because the nock is the conduit of energy between the bow and the arrow, how it comes into contact with the bowstring will affect its accuracy. If the nock fits too tightly on the bowstring, the vibrations of the released bowstring will tend to distort the flight path of the arrow. If it is too loose, the energy transferred from the bowstring will spill over to the sides, not concentrated forward.
Both extremes will make accurate shots much harder, which is why it is imperative that your arrow nocks be just at the correct size. It must be snug enough to firmly 'snap' unto the bowstring, but it must be moveable enough for you to wiggle it up and down the bowstring. This is a good rule of thumb to help you find the exact fit for an arrow nock.
When to use lit nocks
Lit nocks are increasing in popularity, although you may want to reconsider before using them in certain settings.
Lit nocks are great to look at, and they really help you measure the flight path of your arrow during practice sessions. However, you may not want to use them while out hunting. Especially skittish game like mule deer will react to almost any stimuli that come at them, and a bright arrow is a dead give-away that something is up.
If you must use a lit nock for hunting, whether to help you find injured game at night or to make locating} your arrows a bit easier, make sure that each shot you take is as close to the game as possible. If you can manage to catch your prey on their blind side, this makes the use of lit nocks all the better for you.
Or you could just use an expendable arrow to begin with.
Just remember that the arrow nock you use will have a major role in the accuracy and steadfastnessof the shots you make. Determine the fit of your arrow nocks, weigh the pros and negatives of choosing the more fancy ones, and you will find your skills as an archer escalating with time and practice.
