Depth Sounders

Safely check water depths on the go with our portable handheld marine depth sounders — compact, easy-to-use echo sounders perfect for dinghies, inflatables, kayaks, small boats, tenders, or as backup tools on larger yachts.

These battery-powered devices provide instant, accurate readings without permanent installation, ideal for avoiding shallows, scouting anchorages, checking depths from the side, or even underwater use (e.g., by divers).

Our two key models are the Plastimo Echotest II (ultra-simple handheld: totally waterproof to 50m depth, sounds up to 80m/240ft, 200kHz frequency, LED-backlit 7-segment LCD, operates only when immersed, 9V battery for ~500 uses — great for pneumatic/ dinghy sailors and scubadivers measuring seabed, rocks, or quays) and the Norcross Hawkeye Portable Depth Sounder (most versatile handheld sonar: instant depths from 2.5–300ft in 1/10th precision, plus real-time water/air temperature and fish readings, backlit LCD, waterproof, wide-beam scanning for drop-offs/structures — excellent for boating, fishing, or ice use).
