1. Foreword
Thank you for purchasing our company's FP5X
bluetooth fish finder. In order to ensure the correct
and safe use of this product and maximize its
performance, please read this manual carefully
before operation
。
This product is designed with a Bluetooth transfer
function, which can be connected to a mobile phone.
This product operates on rechargeable batteries.
How it works: This product uses sonar to detect
water depth, fish schools, and help you determine the
bottom profile, composition, and structure. The principle
is: the fish finder sends a series of pulsed ultrasonic
waves into the water, the ultrasonic waves propagate in
the water, and when encountering various obstacles, the
echoes are returned to the fish finder. The echoes are
detected by the fish finder and then converted into
electrical signals. The microprocessor uses special
algorithms to process the signals to analyze the
composition, distance and size of obstacles, and the
processing results are displayed on the screen for user
reference.
