How do I get rid of trolling motor interference?
If it is mounted external on the motor’s lower unit, try temporarily moving it away from the lower unit while operating the motor. If the interference is reduced or eliminated during this exercise, you should try to reduce the RF interference by taking a ground wire and connecting it to the trolling motor lower unit.
What causes interference on fish finder?
Most of the time fish finder interference is caused by signals transmitted from nearby boats, but in some cases it can also be caused by electronics on your own boat. Make sure that your electronics are properly grounded, and avoid running electrical cables alongside your transducer cable.
What causes transducer interference?
Acoustical Interference is caused by faulty transducer installation. You will see this noise on the screen only when the boat is traveling across the water, at or beyond the plane speed of the boat. It’s caused by an uneven, or turbulent, water flow across the face of the transducer.
How do I stop sonar interference?
To prevent or eliminate the source of EMI
- Inspect the sonar or data cables for connections at the chartplotter and the cable connector for corrosion.
- Install a ferrite bead or ferrite choke on the transducer cable just before the transducer connects to the chartplotter, sonar module or fishfinder.
Will two fish finders interfere with each other?
Any time you run two units with the same frequency there is a risk of interference. However, with the modern noise rejection systems built into today’s fish finders, in most conditions when there is a unit on the front and back of the boat with the same frequencies, they will not interfere with each other.
What causes trolling motor interference?
The most common cause of sonar interference is when a sonar transducer cable or the transducer itself is too close to a source of EMI. When using an electric trolling motor, the user depresses the throttle on an electric trolling motor.
How close can two transducers be?
If two transducers are transmitting at or close to the same frequency and the signals cross, interference may appear on the display of your Garmin Marine Chartplotter. For best results, two transducers need to have at least a 50 kHz difference in their frequencies to not cause interference.
How much space should be between transducers?
Any distance between the keel and 50% of the distance outboard is preferred.
How do you stop electric interference on a boat?
Turn off each onboard electronic and electrical device one at a time. Switch off every circuit breaker or power switch. Shut down your engine(s). Notice if the interference disappears or continues.
Can I run 2 transducers side by side?
While it is not recommended that more than one transducer be run simultaneously, there can be multiple transducers installed on a boat. If two transducers are transmitting at or close to the same frequency and the signals cross, interference may appear on the display of your Garmin Marine Chartplotter.
Can you put 2 transducers on a trolling motor?
Yes, you can put 2 transducers on a trolling motor, but it’s necessary to make sure that they face in different directions, so you don’t get sonar interference between them.
