Hello everyone,

I own a C Plath made in 1953 and it looks like the one on the right picture. it works very well and it one of the most precise sextants I have.

I have never had a problem in estimating the minute decimals. At the end of the day, an error of 0.1 is not relevant because we are supposed to be sailing and not in a precision contest.

Also, in my experience, the error for not having a portable clock pertectly calibrated with UTC time will generally be higher than the vernier 0.1 error. Just a 5 second time delay might result in close to 1 NM error in the sight reductiion.

I remember Frank saying that the 0.1 vernier scale is a modern marketing technique to give the impression of a higher accuracy, which in my opinion in not the case.

Thanks ! (from somewhere in Japan)
