WTB: Lowrance Shoot-thru-hull transducer (PDRT-WSU)

I got a Lowrance M68c fish finder and need a shoot-thru-hull transducer for my kayak. Just thought to see if you may have one that you want to sell before I buy it on-line.

Thanks

Has any one used one of theses?

Wow, it is cool. Thank you for redirecting me to this info. Here's video -
 

 I still do need a transducer but I think I will buy a skimmer transducer. Anyone has it that you want to sell?   

Looks like they're on the right track,

BUT,

Looks like it plugs the scupper completely, not good.

And,

Anything that protrudes like that will at some point get whacked,

A very simple variation on that theme that I used as a quickie was to run a bungie hook thru the bolt hole on the transducer, run the bungie up thru the scupper, and use it to pull the transducer up tight (and level) against the hull and hook the upper end somewhere to keep it tight.  This also is removable in seconds.

Worked great for me until I got time to glue the puck type in place,

Has any one used one of theses?

I've been curious about it too.
