Description
Handheld depth sounder, of extremely simple operation, particularly intended for pneumatic or dinghy sailors. Equally useful to scubadivers : it gives depth indication relative to the bottom, distance to a rock or to an underwater quay. Totally waterproof, the Echotest II sounds up to 80 metres, and can be used at a maximum depth of 50 metres. Echotest operates only when immersed.
