Best recommendation is that you go to www.garmin.com and read the
descriptions for each.
You can view / download the spec sheets and entire manuals for study.

A brief summary is:
gps 76 the base model of the 76 series. WAAS, lots of waypoint and track
memory;
map 76 map display, has 8 mb of memory for maps
map 76S map display has 24 mb of memory for maps; has an 2 sensors -
barameter and electronic/magnetic compass

The 76 series has the largest display of the handhelds.

Hope this helps.

I am looking for a relatively flexable handheld GPS, for boating and other
uses. I have seen the Garmin 76, but can't tell the difference between a
GPS 76 and GPSMAP 76.

any help/suggestions? thanks.
