 Great back up GPSOct 28, 2009
Bought this as a back up for a boat. Work good, sometimes seems to be off by more than 100 feet, even when located 5 or more satelites.
Good battery life, easy to navigate menus.
Manufacturer should provide GPS-to-USB connector, not only to-Serial, which is not common these days, especially on laptops.
Once connected to PC and software installed, easy to back up and load maps and routes.

excellent for jetski/small boat; shop elsewhere for roadmapsSep 06, 2009
We use this GPS on our SeaDoo GTX, and are very satisfield with its performance out on the water. We use the default maps which came with the unit.
This product works well, but the default maps are not detailed and key roads are missing and are often mislabelled. Using this product to navigate roads would be awful. However, navigation by water is a little better. Several buoys and markers are correct and are in the expected positions on the map. The features which are the most helpful are 1) the breadcrumb trail which is automatically generated and 2) the backlight LCD screen which was a HUGE help to us on a recent trip (from Pt Judith, RI to Block Island, RI) where we got caught out at sea at dusk. This GPS allowed us to follow our earlier-marked trail, so that even though we were out on the ocean and couldn't see very far, we just followed our trail by GPS and navigated home safely. It's also easy to mark points of interest which is critical to finding your way back to the boat ramp in an unfamiliar place!
The item is totally waterproof, and for novice users (like us!), it took about 20 minutes to read through the manual and get up to speed on the key features. It is easy to mark waypoints and good for displaying speeds, time, and the direction we're headed. The item also clearly displays latitude and longitude, so if we had engine problems out on the water, i'm confident we could radio in our position from the GPS and get picked up rather easily.
I wish the screen was a little more resolute. We often have to stop the jetski to take a look at this GPS to figure out where we are and where we are headed, but it's a small price to pay for having the piece of mind out on the water.

 Garmin GPS Map 76May 13, 2009
The 76 is what I thought it would be. Easy to learn how to use. Connects with my laptop for marine charts.
Would buy again
Garmin GPS 76Mar 22, 2009
This is a replacement for me for my old Garmin Map, bought when the
technology was fairly new, but stolen from me. It has a larger map page, great for my old eyes. I had used my old one in the Mojave Desert on cloudy days, followed my "breadcrumb" trail back, and never got lost.
Also did a bit of geocaching -- fun!
A great adjunct for the State topo map books, and very useful on an RV
trip across the USA. Haven't used all the new technology in it, yet, but
look forward to it.

Very useful and versitileNov 23, 2008
I bought the GPSMap 76 because of its quad helix antenna. Reviews of other GPS receivers frequently complained that the satellite signal was lost in trees or under heavy cloud cover. I have yet to lose the signal when outdoors. It can even usually get the signal in my wood frame house.
I originally just wanted an odometer for hiking but decided to get some mapping capability. I have used the GPSMap 76 for hiking, driving and biking. It's not optimized for any of those uses but is pretty good as an all-around unit. If I need a street navigator on a regular basis I would get a unit that specializes in that function. The GPSMap 76 does not calculate routes but you can use the path tool in Google Earth to draw trails, convert them to GPX files with KML2GPX then download them to the GPS receiver. I have found this invaluable when hiking or offroading in unfamiliar areas. It also traces your path which you can upload to your computer and view exactly where you went in Google Earth. When on a long drive I mount it in front of my speedometer and it becomes a map, electronic speedometer and altimeter.
I got the topo maps (pre 2008). Even though these maps are about 30 years old, the streets shown are usually useful for driving. However, when zoomed-out they are very slow to load and too cluttered (the 2008 topo map has very inaccurate street maps). I often use the built-in map for driving but that leave out some major roads.
It's a little large and could really use an SD card slot to save trails. Otherwise it's a good GPS receiver.
