Portable Rechargeable Fish Finder Wireless Sonar Sensor Fishfinder with Water Resistant Bag Case

Castable: No more long and heavy cable for the transducer.
Clear Color Screen: It features a clear color TFT LCD display (2 screen background colors selectable - black and white), allowing you to read the screen in bright sunlight or at night. It applies to lake, river, sea, and other fishing environments. Suitable for fishing from a kayak or boat, casting from the shore, or using for ice fishing. It detects and shows water depth, temperature, fish size (small/medium/big), fish depth, and bottom contour. It includes Work and Simulation Mode. Measure units of depth and temperature can be switched.
Sonar Beam Angle: 105 degrees.
Depth Range: 2.6 -164FT/ 0.8 -50M. Maximum Distance between the sensor and the screen: 262FT/80M. No need to drill a hole in your boat hull to install the sensor anymore. Two small holes on the sensor allow you to tether it with your fishing line and cast it onto the water as far as you want.
Note:
1. Press and hold for 3 seconds to turn on the display.
2. The sensor will turn on automatically when cast into water.
3. When the sensor is off, its battery indicator on the display is incorrect. The red indicator light on the sensor will turn off when it is fully charged. If you would like to check the sensor's battery status from the display, please place the sensor in water. It will turn on when it floats on water. The sensor's battery indicator on the display will then show correctly
