    I like this idea, or one unit with a large enough screen that you can have the different functions all open and usable.

    Re: Transducer Mounting

    I was running 2 different Raymarine with separate frequencies but was still receiving interference, my transducers were side by side. They operate fine separately when one or the other was in the off mode. After talking to the Raymarine technical advisor it was recommended that the transducers should be separated a minimum of 4'. My suggestion is contact the technicians of each product you have for recommendation. The outcome of mine is my older unit finally went kaput as I was at the point of doing the separation. Now my decision is to stay with 1 sonar unit and not deal with trying to add another 2nd unit which I do have sitting in storage.

    Transducer Mounting

    When I get this restoration done, I'm going to run 2 Fish Finders, one Humminbird and one Lowrance.

    Humminbird for GPS mapping and depth. Lowrance for low speed MPH (river trolling as I have a Paddle Wheel transducer for it) also Sonar and water temps. If either show fish, I'll be pleasantly surprised.

    My question is, should I separate the transducers side to side or can they be relatively close together. Yes each will use it's own frequency.

    It's an aluminum boat so through hull won't work.

    Thanks in advance.
