How Close Can Transducers Be Mounted?

Last updated on February 14th, 2024

A transducer is an apparatus that changes a single form of energy into a legible sign. Transducers have an input that is converted to an electrical signal. Common inputs include energy, torque, light, force, motion, acceleration, and any other physical properties. Transducers can be divided into two: regardless of whether or not they need an exterior power source. These are active and passive transducers.

How close the transducers can be mounted?

Transducers can be mounted as close jointly as you deem necessary. The only condition for mounting the transducers it’s that they should not obliterate each other. They can be side to side, or even beside each other.


The Transducers should be placed aft and closer to the centerline. It should be located lowly so that the transducer is in the water at all times. During placement, things like lifting bands trailer bunks, and rollers should be kept in mind. SI/DI and high-speed transducers can be mounted side by side on the same boat without any obstacles. Obstacles can be seen if only both transducers use the same frequency.


The SI transducer mounting tabs should never face forward, not putting into consideration if it’s a bow, transom, or on the side of the kayak. The transducer needs to be mounted nose-up on an average of three degrees about the plane of the hull bottom. In rare cases, a transducer mounted parallel to the hull bottom also performs effectively, however even the smallest nose-down angle can lead to turbulence that destroys performance.

There should be nothing in front, rear, or to the side of the transducer that is more immediate than 12. Do not mount the transducer where it could be impaired from screening, starting, or depository.

Mounting on the ship

The boat should be in water greater than 2 but less than the depth capability of the unit and the transducer should be fully submerged. Put in my mind that the sonar wave is incapable of moving past air. If it is functioning well cautiously increases the speed of the boat to check high-speed execution.

Ensure the bottom of the boat and the transducer are even. If you install the leading edge higher than the boat’s bottom, turbulence can roll from the boat’s edge leading to interference.

The best place to install the fish finder transducers is usually on the starboard (right) side of the pontoon boat. This is because you want to make sure that you have enough cord length to run from the transducer to the fish find monitor on your console, which is typically on the right-hand side of the boat.

The transducer will ring only in water so you need to have it submerged. If it’s too deep sometimes the front face of it will create turbulence and bubbles this can cause it to throw water up over your motor and inside your cowling resulting in a saltwater intrusion.


After mounting you should check whether the transducer is working this is done by turning it on and touching its surfaces.  If it’s working you should be able to feel the sound pulses as vibrations, and often you can also hear them as clicking sounds.
