The Garmin etrex H (high sensitivity) GPS tracking receiver has enough basic features for what I needed at an economical price. My unit cold synced with four or more satellites in less than several minutes inside my house and even in my basement. It definitely has great sensitivity and quick syncing capabilities, when using the WAAS option enabled, which can give up to 10 feet (3 meter) resolution.
I use it for genealogy and other purposes for locating or tracking gravesites, ancestor residences and historical sites, but can be used for any geotagging and geocaching functions. It stores up to 500 waypoints, which I also use for traveling to specific places by foot or car, in case I need to return at a later date.
It's water resistant, which I needed on misty or rainy days plus an adjustable bright LCD display. The backlit feature is nice at night or in shady areas. Even though the LCD isn't color, no big deal for me! The mapping versions use color LCD displays.
It has multiple screens to give enough GPS information on the number of satellites received besides all the typical GPS data. It's easy to navigate through the screens with the five buttons on the side. However the manual isn't really clear as it doesn't show how to get to all screens, but I discovered using the up and down buttons for each page that more screens are available then what the manual indicates. Plus several pages have programmable data displays.
It uses several output formats for computer interface to maps. If you want the maps displayed, then purchase the etrex units with mapping software. It has NEMA183 output data for interface to computers with mapping software. However, the output interface is a basic four pin serial data bus, not an USB bus, which you need to purchase a proprietary serial bus cable from Garmin or other source.
Using AA batteries is important in case you need replacement or rechargeable batteries, available most anywhere. Of course it makes sense to carry an extra pair of extra AA batteries if you expect to use this unit more than the advertised 17 hours.
Overall, I would recommend this product for a basic GPS tracking receiver.
