If used in extreme conditions (heavy surf, etc.) the lanyard may be subjected to forces exceeding 30lbs, so we recommend that you an add additional security leash to ensure that the buoyant lanyard remains connected to the housing.2. The buoyant lanyard is designed to float the a Watershot housing with the associated phone installed. If you are adding additional accessories onto the housing (mounts, lenses, etc.) be sure to check the buoyancy of your full rig to ensure that lanyard is capable of floating your entire set-up.
