I'm planning to upgrade a Garmin 750S chartplotter to a 751XS.
The existing sonar transducer is an in-hull unit. Works fine for my needs.
It seems that Garmin doesn't have an in-hull Chirp transducer for less than a few thousand $.
So is it possible to connect the existing 750S compatible sensor to the 751? I understand this would be very sub-optimal, but it would buy me some time until I can haul the boat and install a through hull transducer later.
Are there more affordable third party in hull transducers for Garmin Chirp?
Roy, I'd try calling Airmar's U.S. distribution branch Gemeco. I doubt there's any source that knows more about transducers, particularly CHIRP. Info here:
