Eventually I'd like to store all my flashlights in Pelican cases (they're waterproof, crushproof, have a purge valve, and bouyant in salt water within a certain weight). You can use the Pick N Pluck foam to keep them from moving around.
Course all my flashlights are water-resistant to begin with BUT they're not bouyant. You know, in case Southern California decides to fall into the Pacific (at least I'd be drowning with a flashlight in my hand... I would'nt have it any other way).
