Lighted nocks can be awesome! However, that being said, I would NOTsuggest the Lumenok. They are to inconsistent and you'll find this be the popular opinion on those nocks. You honestly can't be assured if they will work right out of the package, let alone after only a few shots.

There are several lighted nocks on the market today and THE best available are the Firenocks. They cost a bit more but they are FAR better in consistentcy and performence. They are activated by G-forces and can be shut off with a staright tap on your bow riser, far better than the pull out and twist of the Lumenok. Do some research and read reviews and you'll see for yourself. Good luck and good shootin'
