I have a Helix 7 SI on my boat. My parents have a pontoon that we usually don't use for fishing besides catfish. I rigging it up for night fishing and would like to make it where I can switch my Helix back and fourth from boat to boat. I do not need the DI or SI on the pontoon only sonar and GPS. Can I put a regular sonar transducer on the pontoon and it work properly?
