That's a shame. It was a great customer service program.
IIRC, the plastic through-hull xducer only costs about $60 to begin with. If you can just order one for anywhere near that, you'd be wise to just keep the original one and use it for something else - like ice fishing.
The only drawback to the through-hull xducer is that it lacks the temp probe. I wish it had that, but I love the transducer. Here's mine as installed.
