Average Reviews:
(More customer reviews)I bought this unit for use on hikes, bike rides, and other similar outdoor activities. I've had it for a few months now, and overall, I'm only somewhat satisfied. Here's a list of pros and cons that have stuck with me so far:
Pros:
-easy to read/see color screen (even in bright sunlight)
-highly customizable screens (types and amount of data shown on each screen)
-fairly easy to learn and operate
-many features, including barometric altimeter and electronic compass
Now, the cons to this product may not be specific to this unit. It may be more a function of the limitations of GPS:
-inaccurate (sometimes highly) "tracking" of horizontal position or trail actually traveled (I've compared to trail maps and Google Earth visible trails, and some of my tracks are inexplicably way off)
-inaccurate barometric altimeter (sometimes hundreds of feet off. I've turned it on, and had elevation readings of -200 feet!!) which must be constantly calibrated. Also, if you calibrate at the bottom of a climb, by the time you reach the summit, it may be over 100' off.
-very inaccurate odometer data, and inconsistencies in the data. For example, I recently hiked Half Dome, which is 4800' vertical gain...this unit only registered 1500' total ascent, but the begin elevation and end elevation shown were well over 1500' different. Also, on the same Half Dome hike, the odometer read 5 miles hiked, but the track total registered a more accurate 8.3 miles.
-very "stiff" buttons.
Again, the inaccuracy may be a function of the limitations of GPS, but the odometer inaccuracies in terms of total distance, total ascent, descent, etc. was disppointing. Perhaps Garmin needs to come up with another way of calculating these values. I think a lot of these values are calculated using current horizontal and vertical velocity, which may be inaccurate at any given moment. With inconsistencies at any given moment, it is difficult for the unit to calculate the actual horizontal and vertical distance traveled.
In any case, overall, I would recommend this product for simple trail and waypoint marking. But it should be understood you will only get "general" information, and not anything resembling very accurate data.
**EDIT** Garmin released a firmware patch in Feb of '08, and it has really helped with the accuracy of certain data. The total ascent data is much more accurate now, often within 100' of actual climbed distance (that may not seem so great, but it was horrible before). Also, the distance measurements are better. When I save a track, the distance per the track is much more close to the odometer reading, usually within a mile for a 10-15 mile hike (which again, is just ok, but better than before).
Overall, the unit does seem to be more accurate in all ways now, perhaps due in part to this firmware update. Also, tracks seem to be more accurate in terms of comparing visually to maps. I'm more happy with the unit now, and would probably give it 4 stars if I reviewed it today.

Garmin eTrex Summit HC Handheld GPS ReceiverA staple among outdoor enthusiasts, Garmin's eTrex Summit HC provides peak performance in any environment, making it easy to navigate on the trail or atop the water. The unit is equipped with a high-sensitivity, WAAS-enabled GPS receiver, which locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons. The advantage is clear: whether you're traipsing through thick woods or strolling near tall buildings and trees, you can count on the eTrex Summit HC to help you find your way when you need it the most. At the same time, the Summit HC's easy-to-use menu lets you create and view waypoints (up to 500), save and view 10 track logs, access setup features, and more. It even offers 24 MB of internal memory and a detailed basemap, so you can load waypoints and routes from the included MapSource Trip & Waypoint Manager software and add map detail from Garmin's entire line of optional MapSource mapping products.
Besides appreciating its small size, boaters and outdoorsmen will also be happy with the Summit HC's unique button layout, with five buttons located on either side of the unit. The benefits of this design are twofold: First, the Summit HC is a breeze to operate with just one hand, and, second, with the buttons on both sides of the unit, the bulk of the front is dedicated to the 256-color, sunlight-readable TFT display. This makes it easy to distinguish map details regardless of the time of day.
The Summit HC also includes a built-in electronic compass that provides bearing information even when you're standing still, along with a barometric altimeter that tracks changes in pressure to pinpoint your precise altitude. You can even use the altimeter to plot barometric pressure over time, which can help you keep an eye on changing weather conditions. The Summit HC's basemap, meanwhile, contains lakes, rivers, cities, interstates, national and state highways, railroads, and coastlines--in short, a host of helpful details for your outdoor adventures.
Other features include an IPX7 waterproof housing, a built-in patch antenna, a TrackBack feature that lets you reverse your track and navigate back to your starting point, a USB interface, a hunt/fish calendar, and a geocaching mode. The Summit HC, which runs for up to 14 hours on a pair of AA batteries (not included), measures 2.2 by 4.2 by 1.2 inches (W x H x D) and is backed by a one-year warranty.
