2) How to use the sensor
There are 2 small holes on the sensor. Tether the sensor
with fishing line (not included) and toss it into water. You
can use a rod to guide the sensor to a fix spot or use a
remote-controlled boat to send the sensor to the fishing
spot.
3. Application methods
1) Toss the sensor into water, drag it at a very slowly and
stable speed. It will display information of water under the
sensor, including water depth, bottom contour, and fish
location.
2) Toss the sensor into water, guide it to a desirable
position and let it undisturbed. It will float on water and
monitor submarine news in a real-time method.
Information will be automatically updated on the screen
once fish enter the sensor detection range.
