I have been testing lighted nocks for the "Terry Green - and Smoking Joe Midnight Arrow Project" over the past several months. The "Midnight Arrow Project" is something Terry and I dreamed up for night hunting hogs. The objective is to develop an arrow with a reliable light-up nock and a reflective wrap somewhere on the arrow.
Luminocks: They are OK.
Nockturnal nocks: They are OK.
Firenocks: Excellent and a bit heavy, and you have to install them just right.
Breadcrumb nocks: High quality, very heavy, and very expensive. Interesting Bluetooth feature.
Glory Nocks: Excellent. These are my choice for the best balance of foolproof function, high quality, light weight, and friendly price.
After all of my tests there are some things I like about each of the nocks. But, I will trust my hunting to Glory Nocks with the green LED light.
I also designed a little 2-inch reflective wrap that goes on the shaft directly behind the broadhead.
The combination of reflective wrap on one end of the arrow and lighted nock on the other end looks like it will be a winner for night hunting of hogs.
