Tom & Beth McKenny My wife and I want to thank you. We were on dive one in Grand Cayman, Beth using her Olympus E-PL3 and I had my new Olympus E-PL5. Halfway through the dive, Beth's Leak Detector started to flash. When we looked, there was just the slightest trace of water on the o-ring, but we aborted the dive and headed for the boat. The camera is fine. Your leak detector is definitely the best insurance available. It caught the trace moisture in time to stop the dive, do a partial safety stop, save the camera, and allow us to keep shooting the rest of the week....Thanks Jeff Tom Mckenna - USA
