Product Features

• WIRELESS – No more trouble drilling hole in your boat hull to install the sensor. Simply tie the sensor with a thread and cast it into the water. The sensor will turn on automatically when the switch terminals at the bottom touch water, and send results back to the receiving host.
• LCD DISPLAY – The receiving host has a LCD display which allows you to read in the dark. The information collected from the sensor will be displayed on the host, including water depth, temperature, fish size, bottom contour, battery remaining of the host and the sensor.
• FISH ALARM – When the fish alram is activated, it will alert you when fishes are detected so that you can instantly capture the fishes without watching the float for a long time. Practical and user-friendly.
• WATERPROOF SENSOR – The sensor is waterproof, no need to worry about it being destroyed by water. But the receiving host is for daily water-resistance only, please do not submerge it.
