I would prefer to use a garmin product unless anyone knows of a better that will connect direct to the unit
It's likely that the transducer was an Airmar
as most manufacturers buy them in from Airmar & re-badge them. If done properly, through hull transducers generally
give better results than transom mounted. You need good solid GRP between transducer & water, without any voids, foam, wood etc. The transducer needs fitting to a part of the hull that has smooth un-aerated water flow along it at speed. It's worth playing around with different mounting positions (ooerr missus) to get the best results. Mine is epoxied into the hull & I get a good clear return at all speeds upto 30kn.
