The "New to me boat" has a Zercom flasher

In the dash but no transducer. I have searched around & have not found where to get a replacement ducer. I would like to put another flasher or something in the place of it but not sure what I want just yet. Anyone got any suggestions ? I have looked on eBay for a used flasher with no luck. I already have a rpm, Speedo, fuel gauge & trim gauge. I saw some temp gauges for water & air temp but not sure that is what I want to put in there.


Thanks

They make a digital flasher, need to put something in the whole where my old one is too and with the SI ducer on the back I don't get a reading on plane so it would be handy to have something reading depth at speed.

Here ya go.

Larry, how big is the opening where the devise goes? Is it a 2" or 4" hole?

They do make blank hole fillers if ya can't find one.

Or you could do like DD.......duct tape lol

I believe its a 2 but I still havent pull the unit out to make sure
