The first lesson on how to use a fishfinder starts by reading your product manual in order to familiarize yourself with the workings of the device. To get the most out of your fish finder, you can use the device in conjunction with a chartpotter.

During installation, make sure your fish finder unit has a proper and adequate power supply and a protective fuse. To ensure seamless device operation, trolling motors should not in any way interfere with the fishfinder operation. For example, if you are running a 12V trolling motor, avoid running your fish finder with the same power source as your sonar unit.

 Auto-Depth Feature

However, once you become acquainted with the device, it is important to know that a smaller display window, means better screen resolution. Most professional anglers prefer to stop the scan about 10 feet below the depth of the lake. The horizontal lines that appear on the display window are known as depth cursor. These lines will help you know exactly how deep the fish are before you drop the bait. The cursor can be adjusted up and down.

 

 Suppressor Setting

The suppressor setting will tell you about the noise levels in the background and guide you on how to filter the information out to ensure maximum clarity. To make the changes more efficiently, make sure your transducer is properly mounted. If the settings in your transducer are too high, your sonar signal can be blocked and this will make fish tracking process difficult.

 

 Important Transducer setting tips for your fishfinder

To overcome, the latter challenge, you need to adjust your transducer and change its location, until you get a clear water flow. When choosing the location for your transducer, make sure it is close to the center line of your boat. Transom transducer must always be installed using a transducer mount board and an effective adhesive sealant.

The transducer should also maintain contact with the water at all times. A careful transducer installation process is even more critical, if you are using down imaging fish finder and side imaging sonar. If you have any doubts about mounting or using a fishfinder, don not hesitate to consult a professional. Lastly, the best way to learn how to use a fish finder is going fishing every often and spending more time on the water.
