Datamarine/Pearson transducers

[Shortman]

The original Datamarine Corinthian Series S100 KL Speedo – S200 DL depth sounder on my 85 P-34 no longer work. I would like to replace with something NEMA compatible and less bulky. I am thinking of the Northstar M310 Multi seeming to have good capability and price. Also I am eying their new broadband radar with lust as my Furuno fades, but that is future think, not this year. So, a few questions:
Any experience with these Navico instruments?
Navico Support says their transducers will not fit the old thru hulls. I do not know the transducer size & thread as I am too far away from the boat in the winter but am trying to plan purchases & possible take advantage of Defender's sale this week. Experience with this & know about compatible transducers??
DMI Marine has their Chameleon Sea-M series, and they are familiar with Datamarine, so presumably they either do, or can, fit the transducers to the old thru-hulls. Do not have a price yet but they spec out well. Any experience with these?

Airmar makes all the transducers. Have you contacted them?
Also there is a company who still produces datamarine parts.

but I want to change out to more modern, less bulky, NEMA compatible. I am also concerned about DMI because they have, in the past, not answered e-mail and today I got an answering machine all day and no return call from a message left in the AM, so there's an obvious question re: what if you need support?
I did answer my own question because DMI's Chameleon series is in fact priced on the website & the instrument alone is $575 w/o transducers, which makes them expensive.

Hi All,

I just wanted to let you know. I just aquired all of the parts and schematics from the prior Datamarine Owner. I will be more than happy to support your electronics, and supply parts if you need.

Send me an email if you need anything at all!

Thanks,

Tom
