the Accessory Rail Pole Knuckle allows the quick attachment and removal of submersible video cameras and lights when it is desirable to drop a camera on a pole for searching, or to check for hazards before a diver enters the water Cameras and lights are attached to a “Universal Slide” (sold separately #7024) which is then easily slid on to the accessory rail on the pole knuckle After use, the camera and light can be removed from the knuckle while still mounted on the universal slide and then slid onto an accessory rail on the diver’s mask
