Datamarine Depth Instrument/Transducer
I have a very old, ancient in fact, Datamarine Depth gage. Its on the fritz!

I have already sent the unit out for repair ($100 + buts thats another story for another day) and all looked good there, so it is likely the transducer.

My question...where can I find out of production new or refurbished transducer for Datamarine instruments. I have cruised the web with little success and hoped a sailnetter would know exactly who carries such stuff? :)

Depending on how old it is, Norton's Yachts in Deltaville had someone rebuild my mast head unit....not sure who they used but it worked and was MUCH cheaper than replacing gear.

These are the guys you want...they rebuilt all my units:

Not cheap but easier than replacing everything.

Check the wiring between the transducer and the readout before you get another transducer--Datamarine used some pretty cheap plugs to connect the transducers.

I regularly check eBay for Datamarine parts.

I had the same problem with a Datamarine depth transducer. All my Datamarine instruments were 23 years old at the time. Now you won't want to hear this but, I decided that the instruments had done their job and replaced all of them.

Chart Plotter with Fishfinder
I have a similar problem. I'm considering buying a chart plotter (although I've never used one) that has a built-in fish finder that I would use for depth (I don't fish either). The transducer can be mounted inside the hull anywhere I want.

The unit is about $400, which is cheaper than replacement for my Datamarine sounder.

Any thoughts on this?

Fox, on that sounder for fish, you'll only receive the temp of your hull and bilge water if you install it in the hull. I mounted one off the back of my transom, on the centerline, under the water where not only heel won't affect the measurements, but it stays under and hidden.

t37, what is the matter with your datamarine gauge? what is it doing? I just rebuilt the depth, knots, distance, AWI and speed on my old boat. Perhaps I can help (and save you tons of money in the end!)

Lancer, maybe you can point me in the right direction. I have a Datamarine apparent wind speed/direction instrument. The wind direction works, but not the wind speed. I recently replaced the broken anemometer cups at the masthead, but that didn't help. I expect I'll need to test the continuity of the cable, but, other than that, what is more likely to be the problem? Should I replace the sending unit at the masthead, or should I have the instrument serviced? Any guidance will be appreciated.

I'll second DMI as I've used their services before and find them to be reliable. Yeah you might be able to come across something on ebay, but who knows if it is a good part or not, and who wants to wait for the right part to come along.

I have purchased a new speed log (paddle wheel type) through DMI, had it in 2 days, and it was exactly what I needed.

I'm impressed with DMIs replacement system, and I'll go with it when my 24yr old Datas go bad, but that hasn't happened yet.
