HawkEye DepthTrax 1H Portable Depthfinder. Ref19: MZ-17611
The trouble with most depth sounders is that they can only see what’s in a fairly narrow cone directly under your boat. However, the ultralight handheld DepthTrax™ 1H lets you aim its beam wherever you want to see, like an underwater flashlight.
One slide of the magnetic switch gives real time depth readings, while another slide will indicate the current water or air temperature. Algorithmic programming virtually eliminates false readings while ShootThru Technology allows readings through ice and solid fiberglass or aluminum boat, kayak, or canoe hulls. The impact resistant housing includes a wrist strap and the unit floats if dropped overboard. Since its submersible to 45m you can use it as a range finder while snorkeling and diving.
