Review on Wrist Mount Compass for Ocean Exploration by Mike Roe

Strap is made of fragile Chinese plastic. Not the kind of rubber that should be used for diving. My harness snapped on the second dive I used it on. The strap was a bit loose on my wrist after my first dive that day, so I tightened it by one adjustment hole. When I resurfaced, I noticed that the strap had broken at the adjustment hole, which I had also tightened, and at the hole where I put the extra strap back through the buckle. Replacing the belt costs $30. So wear it a little loose and don't fold over the buckle. Otherwise the compass is excellent and I would give it 5 stars.
