I had some sort of black and white screen Garmin handheld back in the early 90s. You would have to plot the location it gave you on a map to see where you were. I would get maps from Industry Canada for 250k:1 and 50k:1 of the areas I wanted to backpack in, and carry them with me. Worked well, I didn’t get lost I guess, but there was also a lot of dead reckoning when the GPS couldn’t get enough satellites to work.
