    Re: Simex Mariner Polarized Shades...How Well Do They Work/10X Inverting Scope

    Yes, speaking of limited range,the Simex does not lend itself in determining index error via superimposing the Suns(arc set to 0),the index filter having insufficient polarization therefore don't!

    > I agree with Mike. The polarized shades are effective (I have a sextant similar to the Simex) and, as he said, they let you "dial in" a precise amount of shading. They do have a limited overall range, and this can occasionally be a minor nuisance. As for star sights, unless I am mistaken, the polarizers on the Simex can be rotated out of the optical path, just like the shades on other sextants. The 7x35 scope is sufficient for all purposes. If you buy a sextant on ebay with extra scopes that you really don't need, consider selling the scopes separately. They usually fetch a good price.
