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

    I almost forgot the 3 eyepiece shades that are designed to snap on the
    3 scopes of the Simex therefore enabling one to determine the
    aforementoned index error via overlapping Suns.

    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.> > -FER> > >
