Handheld Fish Finder Portable Fishing Kayak Fishfinder Fish Depth Finder Fishing Gear with Sonar Transducer and LCD Display

Displays what's in the water: water depth, approximate fish location (works for various fish types), fish size (small/medium/large), short and tall weeds, sand and rocks at the bottom. Suitable for angling from a kayak, off a dock, and for ice fishing. You can operate the fish finder on a moving kayak at slow speeds under 5 mph (ensure the transducer bottom remains horizontal).
Highly portable for taking anywhere: It includes a neck strap for wearing around your neck when occupied on the kayak. You can conveniently store the fish finder in your tackle box. The device is powered by 4 AAA batteries. It runs for 4-5 hours with fresh batteries under continuous operation. It functions in both fresh water and salt/sea water.
Accurate Depth Reading: The fish finder employs sonar to identify water depth and fish location. Sonar Frequency is 200 kHz. Detection area is a 45-degree beam angle beneath the sonar transducer. Detection depth range extends from 3 ft (1 m) to 328 ft (100 m) below the sonar transducer.
Simple to Use: Cast the transducer into the water and switch on the display unit; it will show water depth and approximate fish depth if fish schools pass by. Features 5 user-selectable sensitivity levels, battery save mode, backlight mode, fish alarm, and unit of measure. Settings are retained when the unit is powered off
