Firenock lighted nock system is not just an ordinary lighted nock, it can be customized to fit your needs.  You can select the model of battery to match your requirements; BL for low to high temperature environments (-4 to 180 °F), BR for lower temperature environments (-17 °F), or BU for ultra long shelf life.  You can change your lighted nock system from hunting to intermittent to hunt for turkey and for ground blind shooting.  You can change your nock color from red to blue or green if you are hunting only at night to enhance your hunting experience.  You can buy O-rings, nocks, end caps, and matched weights in case you need them.  Furthermore, you can even make your Firenock lighted nock system function 20 m deep in saltwater for weeks using the Hydro Bow Fishing System.  Please click below to see all Firenock lighted nock system accessories.  Enjoy!
