When the sensitivity is high, it will show you both big fish and small fish; when it is low, it will only show you the big fish.
Extremely cold weather will impact the performance of the product.
Strong waves, suspended matter and muddy water, will affect the performance.
The fish finder needs to be used in natural waters with water depth of more than 1 meter.
Please do not test it in places such as fish tank, bathtub and swimming pool.
Due to the material of cement or glass, the sonar is vulnerable to the influence of external acoustic wave, resulting in inaccurate display.
