Garmin 750S to 751XS upgrade

Vote 0 Votes

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?
