Dual si transducers

Does anyone run one transducer for the left side imaging and one for the right imaging? I’ve read about it a couple of times, but not sure if there’s really that much benefit?

Seems like a huge waste of money IMO. What would be the purpose? I’m guessing you’d need two screens?

I do, have been for years. Much better results!!!

No motor, or center of boat, cavitation that the sonar needs to “look through”.

In the category of “highly recommended”

I agree. I run two transducers as well.

My helix has the option to split screen of left and right si…then run my maps on the other finder. The transducer is on the right side of the boat. It seems the Left SI is always a worse picture and definition. Like maybe interference from the cavitation or motor? Either way, thinking about putting a second ducer on, but didn’t really know if there’d be a difference

You got it!

I went dual duecer the moment i bought a second SI unit…. Wasn’t about to let one sit idle!

If you have gen 1 units, the cable is quite cheap compared to gen 2. Of course it wasn’t cheap when I bought it!

I’m running a 798 SI as my second, but have a helix 7 did I going to swap in, and figured I’d do the second ducer if it was worth it. Thanks for the input!

OK
Then would it be possible to run the right side off my transom transducer
ands the left side off my trolling motors transducer??

Sounds like it’s possible, but why do it? You’d have a difference in images the length of you boat. And the one on the TM would have more “motion” than the transom.

I run a split SI/DI left and right. I also run a high speed ducer. I have good return images and never loose bottom depths. All are on split cables and mounted on the appropriate spots on my transum.

Using a USB ducer from the trolling motor does not work.

Using an added ducer with a “Y” cable seems unusable to me too.

Wait, let me get an other CC7 maybe it might.
