In choosing the right GPS reciever, the most important thing to know about buying a GPS is what it will be used for. You will notice on the Garmin web-page that the menu is divided by uses rather than models. That’s because different features deal with different conditions well and the whole trick is to get the particular set of features that works for your purpose. For instance the 76S is WASS enabled. This enhancement is newer than DGPS and offers even greater accuracy. Don’t assume though, that because you have the feature that you will always have the benefit of having that feature....
