The light is held in place by a buckle retainer which buckles into the Halcyon Cinch rigid light holder. The waist harness slides freely within this fixture, allowing a diver to loosen or tighten the harness without affecting the light position. The buckle allows the diver to easily adjust the light position or to remove the light while the harness remains secure. The light can be adjusted or removed while in or out of the water.
