The Rayovac that I've been using for years is (of course) discontinued. Best light I've ever had. Outlasted back-up lights used on off-set trips > go figure < Looking at the Pelican 2720 right now...may give it a try. The sensory feature sounds interesting. "Water-Resistant" is normally sufficient for my wet-suiting needs, I've taken uncountable waves over the head, Rayovac keeps ticking, let's hope the Pelican has a good seal.
I actually have the opposite problem that you do...I have a much harder time taking off the small ones,,, day or night....
....Happy Hooking!!!
Sorry, I know that didn't help much, Like you... I guess I'm interested in what others are using (w/success) lately....gotta remember, they aren't going to make them bullet-proof though - because they need you coming back for more every few years...
