Feature:
GEHEN Sonar fish (this device) is a new Bluetooth phone connection fish finder that turns your smartphone or tablet into a full-featured，high-performance color touchscreen sonar system that will outperform many other expensive sonar systems in the market.
Users do not need cell phone signal (traffic) to use it. It can be used in any area of the world and build its own Bluetooth hotspot.
Sonar technology is based on the propagation of sound waves in water.The Sonar fish system uses sonar to locate and determine the bottom structure, bottom profile and fish location, as well as directly detect the bottom depth.
When the Sonar fish sensor is put into the water, the sensor will emit an ultrasonic signal in the water. When the signal encounters the underwater object, it will be reflected back, and then the Sonar fish will calculate its distance and position according to the reflection time and waveform. Then transmit all the information to the screen of your mobile phone or tablet, so that fishing enthusiasts can choose their own fishing position according to the water depth and bottom structure, and the underwater fish condition.
