I want to buy a Used Monitor Wind Vane. Have cash. Will pay shipping
I've seen several Monitors pass through the cruisinsersforum classifieds over time.

Some are old, some look like in good shape. I think there is a difference in manufacturing runs or design change that make certain serial numbers inferior to others. I don't know the details, but I think it has to do with the use of 304 SS vs 316 SS.
If you have the SN of one you are interested in, call Scanmar and they can fill you in.
Yes, I think it was 1996 that they changed the type of stainless to 316. It was a big improvement.
