Sonar to sonar crosstalk interference is generally associated when running 2 units at the same frequency...(as some above have mentioned)...

Hook 'em up... Run 'em both ...see what happens..

If there is interference in either unit.. It would more than likely be powerwire or xducer wire induced interference...

Just spent 2 hours on the water with both the E5DSI and Fishmark 320 running simaltaneously with no interference, no problems. Both worked great.

Now the real problem is figuring out how to interperate the DS sonar screens!! Glad I hooked up both units cause I can't tell anything from the new DS images!! Will take lots o practice!
