Can I Run 2 Fish Finders?

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.

Will 2 transducers interfere with each other?

The interference is typically manageable when the two ‘ducers are separated by a boat length (one at the bow and one on the transom), but

two transducers within a couple of feet of each other on the transom will make for some considerable interference when both are operating

.

Can you run two fish finders one transducer?

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 two transducers be mounted 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 I run 2 Lowrance units off one transducer?

If you wish to concurrently view more than one transducer on your unit at the same time,

set the Network Sonar mode to Multi Source

. For example a split screen showing two (or more) sonar sources.

How do you install two transducers?

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.

How far apart should transducers be on a boat?

The transducer should be mounted forward of the propellers on inboard boats, and separated adequately from other transducers, strakes, rivet lines, or other protrusions that may create turbulence. Make sure there is nothing in front, behind, or to the side of the transducer that is

closer than 12′′

.

Can you mount 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.

How far should a transducer be in the water?

Tip # 3 Waterline

Thirdly the best bet when mounting your transducer to read at speed is to have the bottom of it

3-4 mm below the waterline

. Because the transducer can only ping in water so you do want it submerged. If it’s too deep sometimes the front face of it will create turbulence and bubbles = bad.

Can you mount a transducer on the port side?

I mounted my Transducer on the port side so when I’m fishing its on my side.

If you can mount it 12 to 18 inches from your lower unit you should be fine

. It’s more important to have the transducer mounted properly.

How do you mount 2 transducers on a pontoon boat?

Where should I mount my 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.

Where do you mount transom 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.

Can you connect 2 Lowrance units together?

How do I connect two HD units together?

What is a high speed transducer?

How do I network two helix units?

Can I use the side imaging transducer with my down imaging unit?


Yeah you can

. You need the 5 port ethernet switch. You will then run a cable from your units to the switch. You will plug your transducer into the switch and your gps into the switch.

Can you network a helix 7 and 9?

Can you network the Helix 9 Chirp SI GPS G2N to a Helix 7 DI G2N?

They will network, and they will share the transducer

. You can even save a few more bucks by just getting the Helix 7 G2N with just chirp and gps and they will be able to share sonar, DI, and SI from the 9.

How do you mount multiple transducers on a boat?


Get a long piece of starboard and mount it along the bottom contour. Then mount the transducers to the starboard

. Fewer holes and you can seal off the piece of starboard better. Get a long piece of starboard and mount it along the bottom contour.

Should transducer be submerged?

Note:

the transducer must be submerged in water for reliable transducer detection

. If a transducer is detected, the unit will enter “Start Up” or normal operation unless you choose another option.
