Nearly a year ago I fitted the Leak Detector to my housing .......and
pretty much forgot about it.
A recent dive at Goat Island, a local Marine Reserve, made me appreciate its value.
One of the circlips holding a push button on the back of my housing broke and a leak developed. The bright flashing light on the Leak Detector brought it to my attention almost at once, allowing me to surface with the camera undamaged and less than a tea-spoon of water in the housing.
Any future housings will definitely be fitted with a Leak Detector.
