The best way to tether flashlights and cameras for easy use and access, while preventing loss. Even for the heaviest flashlights, that gain buoyancy underwater, LOCK the unit on land to secure the light/camera. When in the water, UNLOCK for easy, low resistance non-fatigue use of light/camera, yet force is efficient to retract and hold flashlight/camera close to the body. Flashlights are secured to the body and always in the same place, easy to use. Does not restrict the use of your arms or create entanglement issues like a wrist or coil lanyard. Deluxe package includes additional Bracket mount for web straps and weight belts along with extra Q/C-II Lanyard for alternate attachment to large flashlights/cameras. Patented self-flushing system removes sand/salt/debris when operated, and also allows for fresh water rinsing for extended life. Made in USA.
