Transducer interference

[seasick]

I am looking at installing a new plotter/sonar in one of my boats. I am interested in the new Simrad GO7 or 9 XSR model with totalscan transducer. I have an much older Lowrance unit that I would like to keep to use mainly for echo and depth. It has a single frequency transducer at 200kHz
My thoughts based on research leads me to thing that if I configure the new Simrad for 85kHZ, I may be able to use both in echo mode as well as Simrad sidescan/chirp. If I can use both units, a GO7 will be fine. If I can't run both I probably will need to get the 9 inch screen. Space for mounting is an issue.

Anyone out there have feedback on either the Simrad GO series in general and/or the use of two sounders with two separate transducers?
The GO XSR is relatively new but is functionally equivalent to the GO XSE if that helps.

Thanks,
Seasick

I have the discontinued GO7, used for 2 years on my boat. These little units are really impressive, I use mine mainly for sonar, and some Navionics Live stuff. I don't see why you wouldn't be able to run your old unit @ 200k and set the totalscan for med chirp with no interference. With that being said I haven't done it, but I do have two transducers on the boat running at the same time. A speed and depth probe running at 77k, and a high chirp xducer running 150-250k and everything works fine. Good luck!

I have simultaneously run a Lowrance m86c with a glued-down shoot-thru and a Lawrence Elite5dsi with a transom mount. Excellent, no problems.

Thanks for the feedback.

I have Garmin 5208 with the GSD22 sounder powering an Airmar transducer (200 and 50 KHZ) and a GT-51TN sidescan which is powered by a Garmin 94sv and there is no apparent interference.

Forgot to mention that my old boat had a lowrance that could display a dual freq., 50/200K split screen. I always found it interesting to watch the differences between the 2, gives a better total picture of whats beneath the boat :goodjob
