If you have 2 batteries, try wiring them to separate batteries. I have a 334c and a 520c on different batteries with no problems.

I run 2 units on both of my boats and have no trouble but it takes some adjusting. First thing is to set sensitivity to manual, usually about 60-70 percent. Second thing is to turn up the noise rejection to high on both units. Third set the ping speed on the lowrance 510 to 100 percent and about 50 percent on the eagle. If your 510 transducer is an inside shoot thru the hull setup, you probably can't keep them from interfering. You may still get some thin vertical interference lines over a hard bottom or deep water but should be rid of most of it. I check sensitivity with an 1/4 ounce jig head. If I can see it at 15 to 20 feet, I am set about right. Let me know if this helps.

I have the same problem with two eagle finders. I'm on two different batteries and they cross about 20' and deeper. The eagle site says that two don't work together. If I set sensitivity to 60 it won't pick up any kind of fish but may try the other settings. Thanks It's Hummingbird next time for sure!

I have 2 Lowrance units...Both wired direct to my acc. / motor battery..One transducer on the TM the other transducer is on the transon..Both are the same freq. (200mhz)....About 19' appart.
.....Works great is less then 30' of water......After that the sonar "cone" (I think) starts to over lap in 30' of water.
Then I start to get some "cross talk"...
I can adj the units some what to min. the affect.
Best is if you can run different freq. on each transducer.
Just install a 3rd Lowrance unit.....It's a DSI..transducer freq. are 455 and 800mhz........I mounted the tranducer 2' away from the 200mhz transducer on the transon..
Have not had a chance to test it out yet....Hope to get the boat out in the next week or so.
Good Luck
