Everyone should still learn wilderness navigation using topo maps and compass.

First time we used it....years ago, it was about 4 hours before we could obtain a position.

About 5 years ago, it took less than two minutes.

My favorite story is my buddy....said he got to his brothers using his GPS unit with no problem.

Then I asked Richard how many times he had driven to his brothers in the last ten years.

Use to collect GPS with US Air force introduced error (selective availability) and had to obtain file from a nearby CORS (CORS stands for Continuously Operating Reference Stations)to remove the errors. Some of SA error looked like a sine wave others scatter point plots.
