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.
