Stephen, I reviewed the Freiberger yacht sextant's structure here: https://sextantbook.com/?s=Freiberger+yacht+sextant. There are one or two maintenance issues and the horizon shades are at risk when returning it to its case. There is nothing to choose between the fields of view, but I have a preference for half silvered horizon mirrors, as in the Plath instrument, rather than the full silvered mirrors of the Freiberger, for reasons explained in the blog post. I haven't calibrated my Plath yacht sextant (it came to me without its box) but I am prepared to bet that Mr Plath would not have let it out of the factory with the errors that the Freiberger has, though for yachting use they probably don't much matter.
