GPS
What practical things would a handheld GPS unit be useful for?
Are they mainly helpful for interstate travel? I would like to use mine for mapping locations in nature, but it doesn't seem to get precise enough for that. I have the Garmin GPS III. What would be the best and intended use for this machine??

- How is GPS used? GPS receivers collect signals from satellites in view. They display the user's position, velocity, and time, as needed for their marine, terrestrial, or aeronautical applications. Some display additional data, such as distance and bearing to selected waypoints or digital charts.

GPS is used to support land, sea, and airborne navigation, surveying, Geophysical exploration, mapping and geodesy, vehicle location systems, and a wide variety of additional applications.
- The more accurate ones simply cost a lot more - like the Trimbels ($6,000). I use them often for mapping things from weeds to rare plants, to wetlands to selective forestry. They have so many uses from mapping trails, and ecotypes to wildlife. At least, this is the stuff in my field.
- You can use handheld GPS units for surveying. They are accurate to within 1/10 of an inch. These units will bounce a signal off 3 or more satelites to triangulate its position accurately. This type of unit can cost upwards of $20,000.00.
- Handheld GPS can be used as a workout tracker. If you walk or run distances, the unit can tell you how far and how fast you went, with no doubt on accuracy.
