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.
thanks i will give that a try
