Default Sounder capabilities of the Simrad GOs

How good is the sounder in the GO units? I assume i would use the transom mount totalscan ducer.

My boat current has a furuno NN3D system in it with a 1 kw traditional ducer - B258. I would like to add a second screen to my dash and can only fit a 9" unit. I am also interested in sidescan and chirp for use in less than 250 ft of water. I figure for the deeper stuff, I will continue to use the furuno and the B258.

Does the GO sounder work well? Have people had problems? Any idea if the two transducers will interfere with each other?

If I go with the furuno 3D sounder, i then need to upgrade everything to TZT2 and I dont have the budget for that now. Even then furuno suggests having a second ducer for deeper water applications.

any better suggestions?

The High frequency of both would cause interference.

if it was me I would add with the thought of eventually being able to network everything together ie all NSS units from Simrad or all Furuno whatever works best for you.

My understanding is that a TZT2 cannot be in a system with the NN3D network. Additionally I would have to buy the 3D sounder unit and transducer. That is way more than the ~$1200 for GO9.

But if the ducer interferes with the B258, then it doesnt really matter.

The interference is only if you use high frequencies on both. The B258 in 50khz you should be okay with High on the TS. If you use the B258 @ 200khz and medium CHIRP on the TS should be okay as well. There are definitely options to use both at the same time.

Many CHIRP systems / transducers have been found to operate very well with a traditional 50/200 kHz system as long as the CHIRP is not set on a single freq ( Such as 50 or 200 kHz) but firing / sweeping across the band.

Ok - that makes sense about not the same frequency at the same time.

How does the Go9 sounder perform with the total scan ducer? Is among the best available or is it a bargain level entry point? I get that its maybe not the 5100 simrad system for the super deep chirp

The GO XSE sounder is very similar to NSS Evo2, just a bit lower transmit power for the 2D. But with TotalScan max transmit power is no issue, both have much more than this transducer can take.

I have 2 GO7's, one with a regular sonar transducer and the other with a total scan. They are mounted on each side of the out-drive. I can view sonar and structure but not on the same unit and I receive zero interference.
