The Lumenok GT Nock will fit mostly all GoldTip brand arrows (excluding Kinetic). Making them nock specific helps guaranteed a tight and perfect fit every time enabling the components and current to flow every shot. Watching your arrow fly though the air like a laser towards that trophy animal you've been hunting all weekend is like no other and will take your breath away. It also helps greatly at help locating where the animal is hit the second it happens ans you watch the light pass through the animal.
