  1. There are several major factors affecting coordinate accuracy not mentioned here. 1) Position of satelites -- If satelites are all in a row and not spread out across the sky you will find accuracy much harder to arrive at. 2) Check out the computed accuracy on your GPS in most cases they say 25' to 39' or something like that they are not giving you 10' accuracy. Different models compute to a different level of accuracy. 3) In a clear sky with lots (more than 5) satelite accuracy is much better. You will achieve greater accuracy say down to 14'. But for consumer GPSs that is as good as it gets. 4) Satelite drift -- Satelite information drifts a bit for each satelite. This information is computed and fed over RF. This veries constantly (figure daily). When placing a new site, you should take readings at your hide for at least 4 times spread a couple days a part. This will give you a very good ability to give good co-ordinates about your hide. Other's won't say, " I found that 20' the other side of the trail". :-) I have a pro SRS that I use to place my finds, it has all kinds of radio guided drift information with a sub 1 meter accuracy. With tri-cording I can get surveying accuracy of sub 5cm. Wouldn't that take the fun out of finding things if all GPSs were as accurate?
