The Bottomline Fishfinder -- in working order -- can be a real aid to your fishing expedition.
If everything is in working order then the Bottomline Fishfinder can be an invaluable aid on your next fishing expedition. A fishfinder uses state-of-the-art sonar equipment to pinpoint areas inhabited by fish. However, its performance can be affected by a number of issues, including problems with the fuses, debris on the transducer and loose wiring. Many of these issues can be identified and resolved through troubleshooting you can do yourself, without the need for expensive, expert repairs.
Instructions
1. Use a digital multimeter to test the fishfinder's fuse. Turn the multimeter to the Ohm setting and touch the probes to opposite ends of the fuse. If the multimeter reads zero, then the fuse is burned out and needs to be replaced.
2. Visually inspect the wiring which connects the head unit to the transducer for damage or a loose connections. Any frayed wiring can be responsible for erroneous readings or a malfunctioning unit and should be replaced by a qualified dealer before you use the Bottomline Fishfinder again.
3. Check the transducer plug if you find you are getting a distorted picture or nonsensical readings. Disconnect the transducer plug from the back of the unit and inspect it for corrosion, dirt and debris -- and clean it if necessary.
4. Ensure the transducer itself is not damaged. Make sure it's still firmly affixed to the bottom of the boat and with no visible cracks and clean off any algae or debris which may be causing interference.
