Speaking of GPS training...the US Geological Survey also gives free training at the Federal Center in Lakewood. It's the same building where you get various maps. They will emphasize that GPS is a very useful tool, but it does not replace a compass and "real" map. Used together, they are excellent for locating places, getting to and from, planning routes, etc. An important thing to keep in mind is that all maps are not the same. Each has its own "Map Datum" printed on the map, usually near the legend. You have to set your GPS to match the Map Datum, otherwise, nothing will match.GMCO45 said:Was at a free GPS seminar at Gander Mtn today. The seminar was presented by Colorado Firearms Safety Inc. and lasted about 3 hours. The last part was hands on experience with
various brands. While they all had their good points, I was impressed with the ease of using the Garmin units while wearing gloves. That was a big plus with today's weather.
