    Simex Mariner Polarized Shades...How Well Do They Work/10X Inverting Scope
    From: NavList
    Date: 2009 Jan 12, 12:27 -0800

    New to the list, but bought my first sextant at 16 (now 51)...time flies.  
    After taking a break for too many years, I'm back to sailing and have been 
    looking for a new sextant (last got sold for tuition money, so it's been a 
    while).  
    
    There is an unused Simex Mariner with three scopes on the 'Bay (Item Number 
    150320627399) and the only hesitation I have is with the polarized sun 
    shades.  Can anyone comment on how well these work as compared to 
    conventional fixed density filters, and are there issues with the additional 
    optical surfaces attenuating dim stars when set to zero out the polarization?
    
    Also - is there a practical use for the  higher power invertingtelescopes 
    included with some instruments (and with this Simex Mariner)...seems like the 
    7X35 provides enough magnification for tougher shots, and less trouble to 
    keep on target...please educate me.
    
    FWIW, no financial interest, etc. in the auction - just curious to how well 
    the Simex shade systems works, and why it was not adopted by Tamaya, etc.
