Summary: I bought the Garmin eTrex H mainly for hiking. It picks up satellite signals fast, usually in less than 45 seconds in open areas, with ten to eleven satellite signals. The accuracy is about 10 to 15 feet. The backtracking is pretty accurate that provides a safety sense that I would not get lost in the wild. Of course, a compass and a map are needed just in case. The eTrex H is very comfortable in the hand with no rough corners. It has a quality feel.
Summary: My main consideration in making this purchase was the low price offered on sale. I was aware that this was an older model of GPS receiver and did not offer maps on the screen. I use paper maps and a compass and have a strong memory for details I have studied before venturing afield. Note: not sure why it lists "3.5 and 5 inch disks" because these are not included. There is no need for them either. The purpose for which I purchased this was to use in GEO-CACHING.
Summary: it is good for the money but it does not work well under trees. i went out geocaching in the woods and when i found the geocache it was about 30 feet away from the aproxomite spot the gps told me!
Summary: I purchased 9 of these for my high school students to use for an intro geocaching/gps class. They are inexpensive, relatively easy to use with minimal instruction, and the battery life has been good. The accuracy may not be as good as some other units, but usually get us within 15 feet of the desired waypoint in our area. They do tend to jump around in heavier cover, like pine trees. For the money they have been great units for geocaching.
Summary: Basic. However, an enough function. "high sensitivity GPS chip." It is expect in the forests.It becomes a good guide in the mountain where the road is indistinct. The direction of the compass screen and the map screen changes round and round. It is inconvenient for trekking. It continues by eneloop for 17 hours or more. However, the power supply often does OFF once while moving. The connection with PC is RS232C. A special cable is necessary.
Summary: I bought it to locate locations that are given in coordinates. It is a great deal for the price. It is basic with little to know conveniences. Dislikes: You have to go through a series of steps for each and every way point to get to the next way point (a pain). The buttons are rather hard to press. But all in all, it works for a low price and that's what I needed.
