The same caveat about knowing how to use it applies to older technology like compasses and topo maps. I was once in a fairly remote part of Australia about twenty years ago and could not convince a maths graduate that recording positions to the second of a degree was beyound the accurracy of the tools at our disposal, a 1:100 000 map and a ruler!

I have seen a planting instruction for seeds -"spacing 76.2 mm"! The old (Imperial) packet said "3 inch."

Always engage the brain before any thing else.
