Aimed squarely at boaters and marine users, the Garmin GPSMap 76CSx is packed with features that seasoned mariners crave. The 7.6-ounce 76CSx now features an insanely accurate, high-sensitivity GPS receiver by SiRF that tracks your position even in tree cover and canyons. Plus, you get a bright, sunlight-readable color TFT display and an included a 128 MB microSD card for storage of optional map detail. Add all that to the 76CSx's integrated barometric altimeter and electronic compass, and you've got a highly capable unit. Simply put, the 76CSx is ready to take you anywhere on the water. Landlubbers will find much to like about this unit, too, as it packs great GPS mapping capabilities into a compact device.

There are times when "pretty good" isn't good enough. For me, purchasing a GPS unit represented one of those times. I wanted a handheld GPS unit that was best-in-class. My research led me to the GPSMap 76CSx. Factors that led to the decision: frankly, the reviews here; Garmin's reputation; powerful satellite locking; great variety of base- and add-on maps; expandable storage via microSD card; altimeter; compass; battery life; transreflective LCD screen. Don't underestimate the importance of the transreflective screen: one of the biggest consumers of battery power is the LCD: with the backlight on frequently, battery life drops significantly. The transreflective LCD enables you to turn off backlighting for use outdoors during the day, which significantly reduces battery draw.
I like to play with a unit before reading the manual, and in playing around I have figured out the major functions/features. It's not the *most* intuitive unit, but I give it 4/5 stars on intuitiveness. The manual is not huge, but is a several-evening reading project, and that's on my soon-to-do list.
Initial satellite locking is pretty quick (3-4), then acquisition of another 3-4 satellites occurs over the next several minutes. This is *indoors*, where I routinely lock 9 satellites in a townhouse. Out in the woods while hiking, I also lock and hold at least 9 satellites. The more satellites your unit can lock, the more accurate your coordinates are.
I started with using just the built-in basemap, which is ... basic. The first map I added was Topo 2008 USA. While the resolution is only 100k, it adds a reasonable level of topographical detail for my uses (general light hiking), as well as non-routable local roads. (The roads appear and are labelled, but the unit cannot calculate turn-by-turn routing directions using the Topo map. For this, you must add one of the Navigator maps.)
The unit is light, and battery life so far seems as promised (15-20 hours). I have not tried rechargeable batteries, but plan to do so. If they work well, fine, and if not, fine too. Alkalines are inexpensive enough bought in bulk.
Downloading maps from the computer is quite a slow process, so I'm going to guess the USB is 1.1 not 2.0. I downloaded the mid-Atlantic and New England region, approximately 700k of data, which took over 45 minutes. I can't imagine loading the whole country. The Navigator maps may be smaller, since I don't believe they contain elevation data.
All in all, I am very pleased with this unit. The main things a potential buyer must be aware of is the need to add: 1) a larger microSD card to store additional map data; 2) the need to purchase better topographical maps for serious outdoor use; 3) the understanding that while Topo maps show roads, they do not calculate driving routes on these roads; 4) for routable driving maps, you have to add a Navigator type map.
I'm new to using a GPS receiver unit, and frankly I'm impressed with the accuracy, quality and general overall ease of use with this hand held gps unit.
some of the features it has that surprised me,
parachute jump calculator, tells you where you might land based on altitude ect.. very neat feature, I'm sure an advanced parachutist would love this tool that's integrated into the gps functions of :
compass
altimeter (barometric)
speed indication
highly precision GPS location tracking
waypoints, and automatic routing.
In short. VERY COOL, as cool as a car mounted system.
The only issue I had was the maps were kinda useless, all the feature are present for obviously something it doesnt come with, highly updated maps.
THOSE are seperate, and about 200$ extra - but you get the car charger, and mounting system for in car navigation .. it doesnt talk, but it really doesnt need to. the map s are scrollable. and you can quickly find things like gas stations, resturants ect.. specially good if your traveling quite a bit. or even a little to a new area.
I use this for GEOCACHING, it fits in my cargo pockets with ease. it's lightweight, durable, lasts a long time on 2 AA Batteries, and even has options to switch to ni-mh batteries which I happen to have layinga round the house w/ a charger unit for an old camera I used to use.
the screen is color, bright. and what's neat about this unit is.. it has a day/night color change feature, .. so when it flips to nighttime, you can look around the window and say 'yep there goes the sun"
it's accurate too with dates and calender info - such as moon phases.. it has that built in.
there's even tide prediction as well .
For marine use, it's got SOME features. but for general overall everyday use. WOW this thing is packed with features, built in applications. search system to find stuff. and it works great with geocaching.com online .loc uploads.
this has 128 meg Micro SD card built in, larger memory cards are available for very low prices.. I saw 512meg microsd for about 29$
the microsd cards are used to store tracks, waypoints that you add, and additional maps.
I recomend this one over the 60csx, only because it's waterproof submergable, and doesnt ahve a funky antenna sticking up. that will tell people aroudn you you got a gps unit in your hand.
as far as design and buttons, it's easy to use. smooth scrolling. and hihgly configurable to change sensativity ect..
I am returning the 76CSx and getting the eTrex Vista HCx instead. When I pulled the 76CSx from the box, I knew right away this would not work for hiking, geocaching, and biking (the main reasons I use GPS). It is simply too big. I am used to my old eTrex Vista, and the 76 just dwarfs it. I can't believe other reviews that say that the 76 fits "comfortably in my pocket." They haven't seen the eTrex series. I should have known from the product description it was too big, but sometimes it doesn't sink in until you actually see it.
I have no reason to doubt the performance of the 76CSx (I didn't use the one I bought). Perhaps some applications will benefit from the larger size, boating in particular. I do think that the buttons above the screen are problematic, as well as the fact that you have to move your finger off the rocker key to hit "enter" rather than push down on the rocker.
From what I can tell, the Vista HCx will be almost as good in performance to the 76CSx or 60CSX, but much smaller and lighter.
We haven't used this product for driving or boating yet, but we did take it out geocaching. It fits well in my pocket, and after a bit of practice and manual reading the features all seem to work nicely (so far).
Cons:
I think the unit would be better for having a numeric keypad like a cellphone's so that characters (coordinates, especially) could more easily be entered. Entering numbers and names is pretty painful with the soft keyboard.
The screen seems a little small, but on the other hand I wouldn't want the unit to be much bigger.
