RE: Backward Compatible Transducer Question
I have a similar issue where I'm using an old Lowrance X70 monochrome depth sounder I inherited with the boat, which I moved upstairs when I installed a Lowrance GPS/depth colour combo down at the main helm. The old one is very good, in that it does all I need up there, and because it has a good through-hull transducer, and operates on 192 Khz. I can't really see why one should not be able to use that same transducer for a new(er) Lowrance unit which sends at 200KHz, but there appears no alternative to yet another hole in the hull, because the plugs are different. Has anyone just rewired a newer unit to use an older transducer..? The manufacturers just say it can't be done, but not why. I suspect they just want to sell another new transducer. Anybody..?
