"Carefully written and richly illustrated, it is more useful than stock GPS manuals in terms of why and how and is easier to digest than most navigation tomes. The focus is on using a plain GPS with a paper chart, but folks with plotters and PCs will learn something too. If you’re carrying a simple GPS receiver as a backup, this cheat sheet might be handy when and if your PC or plotter goes down."

"Maptech has managed to clearly explain the essential relationship of GPS and traditional charts on a single flip-fold 14"x60" sheet of waterproof paper. Carefully written and richly illustrated, the $20 publication goes well beyond GPS manuals in terms of whys and how-to’s, but is easier to digest than most navigation tomes. The focus is on using a plain GPS with a paper chart, but boaters using plotters and PCs can learn something here too. And given that it's easier to have backup GPS than backup digital charts these days, this reminder sheet might be handy to have when and if your primary electronic navigation goes down."

"Although I rarely use my column space to promote specific products, GPS technology, thanks to a handful of tiny, powerful tools, has the ability to make us better navigators. And by using the Maptech guide, navigation is learned with a lot less drudgery than what I endured during endless celestial navigation courses more than 40 years ago, courtesy of the U.S. Navy."

"Electronic chartplotting is probably the best thing that ever happened to marine navigation-but it can be expensive. What's more, you shouldn't rely solely on electronic charts. That's what the start-up screen on every chartplotter says, yet most of us have become spoiled, letting our basic navigation skills atrophy. With Maptech's new chartplotting primer, you can learn (or relearn) a bit of self-reliance...

Even for the experienced navigator, the training chart can be a helpful refresher on the basics. It's a handy tool to keep onboard in case of emergency, too."

"... takes you step-by step from the dock through a plotted course, using real charts to illustrate examples of GPS use. Each function of this electronic marvel is explained with no superfluous jargon or confusing references to functions that may not be available on your unit. There is even a page explaining basic chart navigation should your GPS fail to function.

The best part is the design of this instructional tool. It is folded accordion style and printed on heavy plastic and is completely waterproof and made to take along. If you are the proud owner of a new GPS but are intimidated by an instructional manual the size of a small novel, this new product from Maptech will give you a great initial overview of how your unit works and how to use it with a chart."
