When you go fishing, sometimes you need a little extra help in locating the fish. That's where a fish finder comes in handy. If the fish finder breaks, however, you might feel out of luck. Thankfully, there are ways to repair fish finders using simple methods. If an at-home fix is all that is needed, you should be back up and running in a matter of minutes.
Press the power button on the fish finder to check to see if it powers up correctly. If the fish finder is not powering up, check the power cables for cracks or frays. If damage is present, remove the cable, unhooking it from the display and power source. Plug in a new power cable into the display and power source. Make sure all connections are tight and secure. Power up the fish finder.
Open the fish finder's fuse box and check for any burnt out fuses. Replace if needed. Check to ensure the red and black battery cables are connected and secure. Locate the boat's fuse box. Check to make sure no fuses are dead or blown. Check that the boat's red and black battery cables are tight and secure.
Inspect the fish finder's display screen for white noise. Too much white noise is a result of interference being picked up by the transducer from the engine or propeller noise. This can be fixed by moving the transducer to a better location away from the engine and propellers.
Remove the transducer either by breaking the epoxy seal or unscrewing from the hull. Locate a new place, close to the middle of the boat, and reattach. Screw it into the hull. Check the transducer cables for breaks or damage. Replace if needed. Ensure the cables from the transducer to the display are tight and secure.
Spray the fish finder's keys with a compressed air can to remove dirt or grime from under the keys that can slow key response. Wash the display and keyboard with warm water to remove build up and dirt that can make keys sticky and slow.
