+Nozzle52 Posted March 7, 2012 Share Posted March 7, 2012 How do i average waypoints when trying to get good coords. for hiding a cache? Quote Link to comment
+WRASTRO Posted March 7, 2012 Share Posted March 7, 2012 With my GPS I stop and set my GPS down for a few minutes. Then I note the coordinates. Quote Link to comment
+StarBrand Posted March 7, 2012 Share Posted March 7, 2012 Many units have an averaging function built in. However, I believe it is generally overrated and doesn't always improve the coordinates enough to make much of a difference. Quote Link to comment
+eusty Posted March 7, 2012 Share Posted March 7, 2012 Use the averaging feature if your GPS has it. Also visit a few times as the conditions which affect GPS accuracy may have changed (cloudy etc) Quote Link to comment
+JoenGPS Posted March 8, 2012 Share Posted March 8, 2012 My wife and I both have a Garmin 60csx. Our technique has resulted in many "spot on coord" comments. We select the hiding spot and walk away about 75 feet (each of us in a different direction). We then walk back to the hiding spot in a close to straight line as we can. Do not stop until you are on top of the hiding place and hit "mark". We have found we are rarely more than 1 or 2 number apart. Your GPS seems to do it's best job when in motion particularly in a straight line. Averaging we get wildly different readings. We then plug in the resultant numbers into each others GPS and test. More often than not my wife's Garmin is slightly more accurate. If it is a tough area (bounce, heavy canopy) and a tough hide, we will wait or come back to test the numbers one more time. No one ever chased us with the bad coords stick using this method Quote Link to comment
+Kryten Posted March 8, 2012 Share Posted March 8, 2012 Averaging is unlikely to improve the accuracy of a fix unless you allow several hours to elapse between each of the readings. Quote Link to comment

If you have a bad signal you're averaging bad data and would probably need to average over a period of days to get a significant improvement in coords. It may sound odd but for the most part the few times I get complaints about coords is when I have averaged. That is because if I have a good signal I don't bother averaging. Quote Link to comment
