  1. I would love to know how to use a sextant. I’ve used a theodolite when I worked for a land surveyor. Alas, I only have a GPS unit. It has maps for all 50 states, Canada and Puerto Rico. One drawback is that it only calculates distances from my current location. For example, if I wanted to know how far it is from NY to LA I have to use other methods. Right now it is telling me that I am 3878 miles from Juneau, Alaska.
