The INSMART Portable Fish Finder is a handheld sonar unit with a wired transducer that reads depth from 3 to 328 ft and marks approximate fish location on a backlit display. It runs on four AAA batteries and offers adjustable sensitivity, a fish alarm and feet/meter switching. It suits kayak anglers, small-boat fishers and ice fishers who want a quick depth check without a full chartplotter. Against fixed-mount fish finders it trades mapping, GPS and screen size for simplicity and portability, and the wired sensor must be submerged and kept below 5 mph.

The INSMART Portable Fish Finder is a handheld sonar depth finder for kayak, small boat and ice fishing. It works in freshwater or saltwater. A wired sonar transducer sends water depth and approximate fish location to a backlit handheld display.
You can adjust the sensitivity, turn on the fish alarm and switch the depth reading between feet and meters. The handheld unit is splash-resistant, so keep it dry.
Submerge the sensor during use. For ice fishing, lower it into the water through an ice hole. Keep moving boat speeds below 5 mph.
