Yeah, that's the one I've got now. The one that came with the 797
was shorter but thicker - squattier I called it

Awhile ago I was doing some reading on one of the unofficial H'bird forums
and ran across this topic - is 997/1197 trans. compatible with 797 head unit.
Humminbird Greg did say that it was, and it will give
"a slightly better detailed image than the 797 transducer does"
In my case, it was more than what I call "slightly" better, but like I said,
maybe my original was not operating at it's best.
