Depthmate Portable Depth Sounder
Provides anchoring security for cruising sailors!
Find deep water easily from your dinghy. This unique pocket-sized depth sounder is very accurate and of very high quality. It's useful for boating, fishing, scuba diving, coastal survey and scientific work.
Reads to the nearest tenth in feet or meters, through a solid hull, inflatable bottom, or black ice. This is an extremely accurate unit when used properly. Simply put the head in the water, or against the solid hull of a boat. (Sonar will not read through air.)
Using the SM-5A improves accuracy at a distance and will be necessary whenever the SM-5 depthsounder alone cannot reach the water. With the transducer at the end of a 12-foot wire, the unit can be used from boats, mounted inside or outside of the hull, or on a pole or boat hook.
