| Book Reviews Buy this book before you buy your GPS. It
will teach you what questions to ask and what the answers mean...there's no better way to
learn the ins and outs of GPS. If you travel far from the beaten path, or in regions without obvious points of
reference, GPS can be a tremendous source of security. Letham's book can explain how
to make the most of that global navigation system...it's a one -- stop source of
information. |
