I have a 20 year old Autohelm ST 30 depth and speed unit that works like a champ, until yesterday when the depth signal stopped and shows 0 feet with the feet indicator flashing. The manual says it is a sign of a bad transducer or a cable or connector issue. Cable looks good, reset the connector which also didn't look bad but still no depth. Any ideas on where to find a replacement transducer. Now owned by Raymarine but their website doesn't show parts that old.

I just hooked a new ST40 head to a 30 year old transducer that originally fed a "Raydata' DISPLAY. Works fine.
I would think finding the correct diameter to fill the hole in the hull will be more of a problem, ask Airmar. They seem to be helpful.

I just put a new transducer in my boat. I called GEM and they were very knowledgeable and helpful. I learned of GEM from Raymarine:
