Right out of the box, the nocks do NOT work. I shot one through a buck with a rage 2″ mechanical tip destroying both deployable blades on the way through. The nock never lit the entire trip. I retrieved the arrow and like the previous one – I experimented with it to get it to function. Removing the tip and with both hands grasping the shaft of the arrow I slammed it down onto a hard piece of rubber and was able to get it to light up. Some WD40 and channel locks were ESSENTIAL for on off function. The You Tube videos claim a rubber arrow extractor works. Not until you exercise these things. RAVIN – Do Your Job!
