You use it to trace roads/trails, etc and it helps you keep track of how long to/from each turnoff, split, bend, etc. Very handy. Problem is, the
Almanac stubbornly refuses to print scale. I have figured it out before and wanna say it's either 250K:1 or 150K:1 Once you get that part down, the
wheel is occasionally very helpful. |
