Thanks for reminding me. Last time I looked they didn't have a web
site, or at least I didn't find it. http://www.sr-i.org/sr/ I have
email them to ask about servicing / reconditioning.

The instruments look virtually identical to the 23 year old units on
the boat. I wonder if they have improved on the technology?

Hey Ryk

You're right - they have not really changed.

I guess there would be a school of thought that they work well and are simple,
don't mess with them any further. A knotmeter for example still usually has a
paddle-wheel to a display unit. Some people like digital, and they consume
electricity. A manual gauge is easy to eyeball, and some can work with no other
electical input than the paddle itself. Simple, and does one thing.

Good Luck
