+Renegade Knight Posted September 23, 2004 Share Posted September 23, 2004 If you have a good signal, your coordinates will be fine. The legend is a perfectly good GPS and very popular. It's not if anyone has hidden a cache with one it's how many thousands have been hid. Quote Link to comment
+Sputnik 57 Posted September 23, 2004 Share Posted September 23, 2004 Markwell has some great information on waypoint averaging on his web site. In fact, there is a lot of good info about geocaching in general there. I highly recommend it. Quote Link to comment

+Renegade Knight Posted September 23, 2004 Share Posted September 23, 2004 Hey does the legend have auto averaging?which other gps have auto averaging? The legend doesn't have auto averaging. The eTrex series in general don't. I'm not sure about the new eTrex colors. However averaging will only pick you up about 3 feet of accuracey give or take. To truly have a good average you need to come back and make a measurement with variouse satallite constelations. Averaging while you are standing there is just averaging the current conditions and your GPS is allready good enough for that with a single reading. My observations. None scientific.

Phoenix2001 Posted September 23, 2004 Share Posted September 23, 2004 Hey does the legend have auto averaging?which other gps have auto averaging? Garmin receivers do not have auto averaging, Magellan receivers have auto averaging. The Garmin original eTrex series does not have any waypoint averaging but other Garmin receivers (12XL, 76 series, the new Legend C/Vista C, 60C) have a user command to average. Quote Link to comment

Averaging while you are standing there is just averaging the current conditions and your GPS is allready good enough for that with a single reading. My observations. None scientific. Good observations. In general short term averaging (minutes) doesn't really help when the conditions are good. If the conditions are bad, some averaging can help. General comments..... If you're trying to mark the location of your cache, try walking away at least 50 yards/meters and back and in different directions. Note the readings you get at the cache. If you have good conditions the readings will be close, if you have bad conditions the readings will probably vary a fair amount in which case you might average them. Best is to try to get multiple marks at different times (different satellite constellations with good dispersion) on different days. Note that you get the same satellite constellation 4 minutes earlier each day. Don't take a reading when a major solar storm hits unless you are using DGPS processing (ie WAAS) to get the correct ionosphere delays. The USFS tests at the Clackamas site have some good info.... http://www.fs.fed.us/database/gps/gpsusfs.htm http://users.erols.com/dlwilson/gps.htm http://www.gpsnuts.com/myGPS/GPS/Technical...curacy_by_c.htm Quote Link to comment
