I have one with speed and temp for a Garmin 240(fits other models also I believe). I want one w/o speed I can mount to shoot thru the hull. I think the paddle wheel speed sensor will be in the way and epoxying it to the hull would be a waste if someone would use it. I don't really need the speed and I have a temp guage. So if anyone wants to swap I'd be more than happy to. A new transducer costs $60 and I just thought I'd give this a try first.
