While it may not make the "necessity" list for your trip, this product will cer- tainly qualify as the coolest accessory you'll likely ever pack. And if you find yourself in the dark and needing a larger field of vision than a flashlight or a spotlight can provide, switch on the Explorer Marine for an eerie glowing green view of your surroundings-even in total darkness. The waterproof rubber body should be plenty tough to handle any marine environment- plus it floats.
