4. Attentions
1) The host is not waterproof. If water splashes on the host,
please dry it immediately.
2) The sensor is supposed to float on water when working.
Please don’t drag it into water bottom, or submerge and
hold the whole sensor under water.
3) Its reading might be interfered with other high power
sonar device close to your sonar sensor.
4) If water wave is too strong, please protect the sensor
from crashing into rock. Otherwise it will cause irreparable
damage to the sensor.
5) The fish finder will only operate properly in open water
that is deeper than 2.6 feet.
How to Use the Sonar Sensor
1. How the sonar fish finder works
1) The system uses sonar to locate
and define structure, bottom contour,
and depth directly below the sensor.
It transmits sound pulse from the
sensor, and then measures the time
it takes for the echoes to return to
the sensor. Different objects in water echo the pulse at a
