+Stumblefoot Posted May 31, 2003 Share Posted May 31, 2003 I am very new to this (started two days ago). I missed my first one, but found it the next day after I adjusted my datum. Yesterday I found one but missed the other after looking for over an hour. My GPS (Magellon 315) said I was there at serveral different places. Is it typical to have to look around for the cache? How far should I look? Quote Link to comment
+BigJon Posted May 31, 2003 Share Posted May 31, 2003 Yes a margin of error is normal for your GPS and the you have to add in the margin of error for the person that placed it. I usallay start looking when my GPS says I am within 15ft. Once I find the cache I am usally within 2 - 6ft of it. So if you figure my 2 - 6ft error and thier 2 - 6ft error you can see what kind of an area you need to look in. This is just me but I know once I get within my range I start looking at the terrian and can usally spot good loc's for a cache. To answer your question yes you will have a margin of error.

+Renegade Knight Posted May 31, 2003 Share Posted May 31, 2003 There are a lot of factors that can impact your 'zero' location. It's not unusual to be sent to two or three spots in a general area as the GPS changes it's mind. The cache is normally close or often bounded by the area. ===================== Wherever you go there you are. Quote Link to comment
+MountainMudbug Posted May 31, 2003 Share Posted May 31, 2003 It took me about 20-25 caching trips until I started to be able to 'zero in' better on the hiding spot. Having become more comfortable and capable with the GPS, I've also developed a better nose for hiding spots (aka 7th sense: cache sense). I still get skunked sometimes, but luckily my caching partner has been getting better and finding some himself recently - usually he just follows my trail of dust.... Quote Link to comment

I also use a 315 as well as a etrek, I have found if when you get close and it starts this dance, turn it off and re-start it ~~ it will usually lock on (like already mentioned there is the error factor X 2) Mzee ~~~ "And now where" Quote Link to comment
+briansnat Posted May 31, 2003 Share Posted May 31, 2003 It's normal to be as far as 40 -60 feet off when you factor in your unit's margin of error and that of the person who placed it. "Au pays des aveugles, les borgnes sont rois" Quote Link to comment
Eeyore and Shadow Posted May 31, 2003 Share Posted May 31, 2003 Magellan 315 has an EPE (estimated position error) which tells you how inaccurate the coords that it is displaying could be. But EPE is only avaliable in the main nav screen and it only works while you are moving, when its not moving it starts averaging and doesn't display the EPE. Try going to where the coords say is correct, stop and wait a minute to make sure that its not going to float (move slightly as it gets stronger/weaker signals) looking at the main nav screen start walking untill it stops averaging and shows the EPE, then you will have an idea of how far you could be from the stated coords. Eeyore I'm one sat short of triangulation. Quote Link to comment
