The message

from "Man at B&Q" contains these words:

LOL. I guess handheld GPS must be useful to those who can't navigate
the old fashioned way, otherwise Garmin and others would surely never
have introduced them in the first place.

Hand held GPS can be useful even to those who can navigate the old
fashioned way. However I remain to be convinced of the usefulness of a
compass whose accuracy is quoted as plus/minus 5 degrees.
