Lowrance & Marcum together on back of boat

[lumpy]

I was interested in running my Marcum flasher at the back of my boat. I have a Lowrance lms-320 which operates at 200 khz. I believe the Marcum operates at the same frequency. Is it possible to use them together? I know the Marcum has some interference rejection and that could allow it run beside the Lowrance but does the Lowrance have the same capability?

Anyone have any experience with this?

Right now I have a second graph, a older Sitex CVS-106 video graph that runs at a different frequency. It came with my boat so I just added the lowrance to have a gps with MMC chips and graph. The Sitex doesn't work very well when I speed up the boat a little to look for fish.

You might get some interference!! I tried running an LMS 350A and an X-15 together and wouldn't work. I'd lose signal lock on one or the other. These both ran at the same freq.

I run two finders an X-65 and Fish Eagle with both transducers in back. There is definite interference between the two at running speed. I have to shut the forward unit off when I move to my next spot or will give the X65 dash unit a brain f--t. I still prefer it over running another wire up the trolling motor I always got it caught on stuff.

My x-51 interfers with my marcum, even when they are at different ends of my boat, the marcum is still usable with the x-51 on, but there is interference. Not that it bothers me, I use the flasher, and turn the other one off. 90% OF use for my x-51 is depth and structure only, I use the LX3 to tell me if there is fish there or not.
