Garmin GPSMAP 76 Waterproof Handheld GPS by Garmin (Electronics Edition) at ApexCamera.com

In addition to being relatively easy to use, I preferred the slightly larger screen of the Map76 over the other units. Since I was purchasing the unit to use while sea kayaking, I found the screen on the Map76 was much easier to read in the sunlight than the smaller screens on the E-Trex models. In addition, you can upload map data into this unit. (Although the unit includes a basemap, Garmin also manufactures a number of optional mapping products which cover roads, waterways and topographical features in more detail). For kayaking, I use the optional BlueCharts which is essentially like having Nautical maps at your fingertips. (These are sold by regions and tend to be a bit expensive however).

The tide station/prediction feature on the Map76 was also an important deciding factor. With this unit, you have the ability to get tidal predictions for virtually anywhere in the US at your fingertips.

The Map76 often receives criticism on the low amount of memory for uploading map data. The tradeoff however is that it also drains the battery power at a slower rate than those that boast more memory. (I also considered the GPS Map76S which has an added electronic compass and more memory, however after a trial use from a friend's, I found the Map76S unit to drain battery power far too quickly for my intended use. The Map76S was also about $100 more in cost). Although the Map76S was a slightly upgraded Map76, I didn't feel the extra features of the 76S were worth the added cost, especially with the faster rate of the battery drain.

I've logged over 500 miles of sea kayaking with this unit and am very satisfied with its performance. I find the memory capability in the Map76 is adequate for uploading maps for day trips and the balance with the battery drain is also sufficient.

Although it is waterproof, I highly suggest a transparent waterproof bag for using while kayaking to avoid salt water condensation corroding the battery leads.

Garmin also offers toll free phone and email technical support for their units and software.

Summary of Garmin GPSMAP 76 Waterproof Handheld GPS

About the size of a small paperback book and weighing less than 8 ounces, the GPSMAP 76 fits comfortable in the palm of your hand, but is a bit big to carry in a shirt pocket. Using the unit requires almost no setup. Just put in two AA batteries, turn it on, go outside, and wait. In about a minute or so it will determine your location. It's accurate to about three meters, thanks to the unit's support of WAAS (Wide Area Augmentation System), which augments GPS signals for even greater accuracy.

Knowing your longitude, latitude, and altitude doesn't mean much without a little context. That's where GPSMAP 76's backlit LCD display comes in, displaying your location on detailed maps. The unit comes with a built-in basemap that includes major roads, railroads, rivers, and lakes for the U.S. and Canada, as well as a high-level worldwide map. The unit also has 8 MB memory for storing maps from optional CD-ROMS; available maps include topographical maps, BlueChart marine cartography maps, as well as city maps with detailed information on city streets and points of interest.

The eight buttons, directional rocker thumbpad, and menu-based interface made it simple to access all of the unit's features and customize the display. For instance, it's a simple matter to use the buttons to set and name waypoints and build planned routes. Extra features include information on tides, sunrise and sunset, and a trip computer for seeing how far you've traveled and your average speed.

To test the GPSMAP 76, we used the included serial cable, connected it to our PC, and loaded it up with topographical maps using the optional United States topographical map disc. We then hit the road and headed for Muir Beach north of San Francisco. It tracked our progress along Highway 1, and once we reached our destination, we found it very simple to use. It showed both the elevation of the hills as well as the paths we could take. The zoom-in and zoom-out function made it simple to plan out and automatically measure the distance of our intended route.

After walking for a while and enjoying the scenery, we used the TracBack mode to guide us back to our car. The unit automatically stores waypoints as you walk along, letting you display the way home clearly on the map. We even used the TracBack capability to guide us on the roads back to the freeway.

The GPSMAP 76 comes in handy almost anywhere, whether you're hiking, driving, boating, or wandering around a city as a tourist. Its easy-to-use interface makes it immediately useful to novices, and as you learn to exploit its programmability and features, it can become an extremely powerful navigation tool. --Ken Feinstein
