"My second 76 series GPS"
I liked the 76S that I bought several years ago so much that I wanted another in the same series when I upgraded. This is so much quicker, and it has so many new features, especially greatly increased memory, and it cost considerably less than the 76S. The one thing I've found lacking is that the tide feature the 76S had only comes with another $120+ of marine software for the 76CSX. We live near salt water and it adds to the usefulness when we're camping if we know what the tides are doing. Is there anyway I can download this into my new GPS?

"Great"
Great overall product.

Very rugged, good battery life, great support.

Small complaints: small screen, slow processor at times, button interface is slow entering input.

No surprises really though. I love it.

"Meets my GPS needs"
I was looking for a water proof GPS unit to take both tour kayaking & backpacking. Looked around for at least a year then bought this one. Having logged over 100 mi. paddled this season I can say that it works well in water. I typically mount it under the forward deck lines & secure it with a clip. No water problems so far, it's been pounded by many waves. -I'm more worried about heat from sun than the water. Having the compass navigate a course on water has come in handy, I sometimes paddle in fog or bad weather. Match my heading to the bearing of the next way point & I'm going the right way. It can tell me distance left to go, time remaining at current speed, etc. I have found that for the compass to work well when traveling at low speeds some settings need adjustment but after that compass is reliable and self adjusts for magnetic variance.
I save all my tracks to an SD card in the unit. When I get home I upload the tracks to the computer, where on the larger screen I can see everything. Calling up the track with google earth and having them overlaid on 3D Sat. images is jaw dropping, this capability is standard with the included "Map source" software. Often I choose not to look at the GPS while out & find out where I've been after I get home. I have a minor gripe with the altimeter, the reading fluctuates while standing still & the profile view in "map source" is not as dynamic as I'd like. Still it is better than no altimeter, and can give a rough idea of peaks troughs, etc. I just wouldn't jump from a plane with it. I really like observing the profile on the unit then moving the cross hairs over a particular peek and pressing [enter] it brings up the map page and the pointer shows that particular point on my journey, this often makes peek elevations & identifications quick and easy. Note: while on the trail, bug spray eats away at the screen, one small corner of mine got some bug spray on it & now it is slightly cloudy.
Hard key pad buttons make navigating the screens easy but only after you get the hang of where things are. Battery life is excellent, exceeding my expectations. Screen is small for Topo reading, but this unit should NEVER replace a paper map on the hiking trail, or even kayaking. I use the statistics page more than the map page anyway. It can give me my moving average, total time on trail & total moving time as well as distance, altitude gained, etc. All a much better use for the device than as a map. Maps that come with the device ON THE COMPUTER are detailed enough for interesting uploads, but the devices base map is like a blank canvas. So if you are strictly using it to track where you have gone & upload to the "map source" program on the computer additional maps may not be necessary. However if you plan to plot courses or use the device for road navigation you will probably need additional map software. I have also used this device for car travel but this it is not it's strong suit. It will not impress but might satisfy.
-Topo 2008 maps improves terrain maps on the unit (including coastal outlines) and improves road maps greatly. Initially I had expected to need road map software as well for any road info at all but the topo 2008 software had plenty of small roads, points of interest, direction computation, etc. So far I have no need for additional maps. The only time I have lost a sat. signal is in a cave or a tunnel so far.
Overall a great unit. Technologically the best civilians can get for outdoor use at this time -so 5 stars.

"Garmin 76CSX"
This is a great gps. It receives signal anywhere I have taken it(woods, basement, any buildings). It is everything you will ever need in a hand held gps unit. The only thing that would make it better, is if it came with the topo maps instead of having to purchase them separately.

"Bad display, bad graphics, very disappointed"
I don't know if any device maker can still find such a lousy LCD screen to put into their design; the LCD screen of this product reminds me a 1980 PC with really bad graphics display, and they still manage to charge people with a premium price. Nowadays, a $500 PC with more expensive components has a screen much bigger and better. This small device made by Garmin is a rip-off, just from the LCD point of view.
