When you said he used it as a step! Hat off to you for maintaining your composure!
The transducer comes in a variety of specifications and I donít think thereís repair kits. Itís a sealed unit on a length of cable. You can attach the new transducer cable to the old transducer cable and haul that back through .
Things to consider is compatibility. I donít know enough about the technology, but some of these transducers, certainly side scan are expensive. More details here: https://www.garmin.com/en-GB/c/marin...?currentPage=1
Are you sure the damaged one canít be repaired or some sort of fibreglass resin substitute to reform the lugs? Any pictures?
