Can You Use 2 Fish Finders At The Same Time?

by | Last updated on January 24, 2024

, , , ,


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.

How close can transducers be to each other?

While it is not recommended that more than one transducer be run simultaneously,

there can be multiple transducers installed on a boat

. … For best results, two transducers need to have at least a 50 kHz difference in their frequencies to not cause interference.

Can you mount transducers side by side?

You can mount SI/DI and high speed transducers side

by side on the same side of the boat without any problems

. When they both transducers use the same frequency is when you may experience interference.

Can you mount a transducer sideways?

Yes, it will work.

You can find stuff to the side

.

Do multiple transducers interfere with each other?


If both transducers are using the same frequency, they will interfere with each other once you reach a water depth

that allows the two beams to cross. In shallow water, they may work together if the transducers are far enough apart. … Setting each unit on a different frequency will prevent interference.

Which direction does a transducer read?

The general rule of thumb is to mount the transducer to

the starboard side

, which is the down stroke of most single outboard boat propellers (right hand lower unit).

Can you run 2 Lowrance units off one transducer?

If both transducers are using the same frequency, they will interfere with each other once you reach a water depth that allows the two beams to cross. … If you are limited to using the same transducer frequency on each unit, you

will have to run one at a time

to avoid interference.

Can you put 2 transducers on a trolling motor?

You can mount

SI/DI and high speed transducers side by side on the same side of the boat

without any problems. When they both transducers use the same frequency is when you may experience interference.

How do you mount a Lowrance transducer?

The general rule of thumb is to mount the transducer to

the starboard side

, which is the down stroke of most single outboard boat propellers (right hand lower unit). This side produces the least amount of turbulence and is most efficient in delivering the best performance.

Can you have 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

. … For best results, two transducers need to have at least a 50 kHz difference in their frequencies to not cause interference.

Will a transducer work backwards?

The transducers are calibrated and made to mount on the transom with a left and right but

when mounting them on the bow of the boat left and right are reversed

. If you mount the transducer as shown in Brian’s photo above, it should be oriented correctly.

Where is the best place to mount a transducer?

Transducer placement should be

aft and close to the centerline

. It needs to be located low enough that the transducer is in the water at all times. Consider items such as the lifting strap placement into the location as well as trailer bunks and rollers if it is a trailered vessel.

Can you run 2 fish finders off 1 transducer?

You CAN run two Fish finders on Different Frequency’s, you

will not be able to run both

at 200kHz one must be 83 or 50 kHz. Depending on what brand of fish finder you will run , some will allow two or more monitors linked to just one transducer using a Nema 2000 backbone.

Can you run two Helix on transducer?


Yes via Ethernet

. I see you have a 360 and two displays now. If you have all three connected via Ethernet, you can do it now. Just turn Sonar OFF with one of the units—same as disconnecting the transducer.

Can you run 2 Lowrance units together?


The Lowrance Hook 2 Series cannot be linked together

. If you want a Lowrance unit that can be linked together you will need to upgrade to the Elite Ti series, Hds Gen 3 Series, or the Hds Carbon Series. Waypoints can be shared through the NMEA port on the Elite TI, but both units have to be turned on for this to work.

Where do you mount a Lowrance Tripleshot transducer?

Transducer placement should be

aft and close to the centerline

. It needs to be located low enough that the transducer is in the water at all times. Consider items such as the lifting strap placement into the location as well as trailer bunks and rollers if it is a trailered vessel.
