To make sure your fishfinder is operating properly and provides accurate information, testing it is a crucial step. To test your fishfinder, take the following actions:
Check that all displays and indicators are working properly by turning on the fishfinder.
Make sure the transducer is positioned and aligned correctly before lowering it into the water.
To check if the fishfinder accurately displays depth, fish, and other information, move the boat or kayak while keeping an eye on it.
Any problems or differences should be noted and addressed as needed
