Really watertight


from Miami, FL, US

I just return from a trip on Bonaire, and since you can not leave anything in the pick up truck rented over there because of theft, I needed a watertight box to take a Garmin Montana GPS (used to drive over there) underwater to SCUBA dive, first I tested the box empty to 100 ft for 15 minutes, in my first dive, since didn't leak, I used with the GPS for the rest of my 25 dives, and work perfect, a recommendation is to put a tight wrap around the box over the lock, so won't open accidentally.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Can this fit the Analox O2EII Pro Nitrox Analyzer?
KEVIN F  Yes, it fits. It's a snug fit, but it works.
Edwin F  Can I store a full size glock hand gun ?
MARK H  I assume your glock would be similar in size to my Ruger P89 and my Ruger wouldn't fit even with the padding removed. My wife has a small Ruger LC9 and I doubt it would fit. The opening is only about 3 1/2".
