Once you have the boat you’ve always wanted, the next exciting thing to do is to outfit it with electronics that will keep you boating safely, finding the fish, and navigating to where you want to go.

For the mariner, they can serve as the main navigation computer or be a viable backup to permanently installed onboard gear. Accurate position, speed, and course information supplied by a handheld GPS used in conjunction with a paper chart should be all you need to complete any voyage. When they are so equipped, many of the handheld marine GPS review units we tested are also good at supplying accurate lunar, solar, and tidal data in user-friendly format. Some of this type of information can be critical to a new navigator or novice boater arriving in an unfamiliar port or marina. One thing these units don’t do very well is display easy to read charts like you’d find on a large screen fixed-mount chartplotter. Early handhelds were especially lacking here for two reasons.

First, screen size on a handheld is simply not large enough to display the huge volume of data needed to make a map display useful and accurate. Increasing screen sizes on recently released handhelds have help here.
Second, memory and processor capability was very limited in the earliest mapping handhelds. Newer handhelds have made significant strides in the hardware arena with big increases in computing power and lots more memory.

The units we’ll review here have prices ranging from under $100 up to near the approximate $400 starting price of a fixed mount chartplotter.
Boaters looking to meet basic navigation needs without buying a fixed mount chartplotter should check out a handheld GPS unit. They cost significantly less money.
