Great Hack! but don’t mess around with your eyes!

Why use a sextant when GPS is available?
In practical terms, you wouldnt. But, then again, being lost in the arctic, or lost on the ocean after a storm killed your electronics… times like that when “practical” is lost in the “unlikely event” splatter. Its nice to know how celestial navigation works – GPS is really not much different conceptually. Its also nice to be able to independently verify the accuracy of your GPS.
Well,can anyone please describe me the working of cd sextant.
