How to Fix a Hummingbird DI That Doesn’t Work

If your sonar has stopped working, or your DI is not showing any fish, it is likely that your unit is not working properly. Fortunately, you can fix this easily by following some simple steps. First, check the unit’s frequency. It should be 1.2 MHz or higher. portable fish finders

Check the transducer. It should be able to pick up fish and other underwater objects. If you don’t get a clear picture, it could be because of surface clutter. This is caused by many factors, including the water density, waves and other objects in the water. This is called “blind zone” and can lead to incorrect readings.

The horizontal axis of the sonar display should show distance and time. If you are reeling in, keep your speed steady so the sonar can continue scanning. Also, if the sonar has a mapping feature, make sure you keep a constant speed. This helps the device to provide accurate depth maps.

A traditional two-dimensional sonar uses a cone-shaped beam to scan the water column directly below the boat. The higher the frequency, the narrower the cone. The lower frequency, on the other hand, gives more coverage area and a wider angle. This is beneficial for hunting fish.

If the sonar stops working, check the wiring. The unit may need to be connected to the transducer via separate wires. If this is not the case, check the transducer’s bottom resistance. It is possible that the transducer is losing bottom because of cavitation. If this is the case, consult a professional for help.

Many fish finders come with special software that enables you to create custom maps for unmapped waters. By idleing over the area in a crisscross pattern, you can create a custom map for the water. The software will then turn on the bottom contours and bring them to life.

Another common problem with a fish finder is a malfunctioning transducer. If the transducer is oriented incorrectly or has become bent, you will not be able to use it. The transducer may also be damaged due to barnacles, dirt, or cavitation. A bent transducer will affect the signal, so make sure that the transducer is properly oriented towards the bottom.
