Garmin GPSMap 76/76S Review
Garmin for several years have had the GPSMap 76 and 76S available. These are very rugged Marine style GPS which can be used on land with MapSource maps and give you everything you would conceivably want in a GPS with lots of memory to install Garmin Cartography, to Electronic and Barometric Altimeter's in the 76S.
These are not small GPS Receivers like the Garmin eTrex or Geko range, they are large, but do allow you a much larger and better screen compared with other Garmin GPS Receivers.
In The Box
The Garmin GPSMap 76 / 76S comes complete with the following items:-
- GPSMap 76 / 76S Handheld GPS
- European Basemap
- PC Interface cable (Serial) for Garmin GPSMap 76 / 76S
- Wrist Strap
- Manual
- Quick Start Guide
Mapping Software
The GPSMap 76 / 76S does not come with any mapping software out of the box, so if you do need maps on the handheld then you will need to purchase one of the many Garmin MapSource CD's. These range from Topo to Street Maps from North America, to Europe. In-fact maps are available for Western Europe and North America and also for some non Pan European or North American countries too!
Screen Technology
The new Garmin 76 / 76S screen is a grayscale screen. If you are looking for a bright vibrant colour TFT screen then you may want to check out the GPSMap 76C / 76CS review.
Battery Usage
- 16 hours (GPSMap 76)
- 10 Hours (GPSMap 76S)
You don't have to have the backlit screen on all the time, when you are out on a bright and sunny day as the screen is trans reflective it makes more sense turning off the backlit screen and allowing natural light to light up the screen.
Memory
Unfortunately memory is not expandable in any of these GPS Receivers, but you do get a fair amount of memory for what you would need in most cases.
- 8mb (GPSMap 76)
- 24mb (GPSMap 76S)
Basemap
The basemap installed in UK versions cover Europe and is not changeable and cannot be modified in any way. US based versions will come with a USA basemap. Basemap's are not that accurate so if you want to see streets it is better to add a MapSource CD to your collection.

So in a nutshell if you are looking for an accurate compass which does not require line of sight to the GPS Satellites and for you to be moving, and/or you would prefer a proper barometric altimeter than the Garmin GPSMap 76S is the better choice of the two. If an Electronic Compass and Barometric Altimeter are not really in your wish list then a GPSMap 76 will more than supply the features you need.
