dbowers Posted January 28, 2006 Share Posted January 28, 2006 Hello, first post here and just have a little question. I am new to geo caching, but have been using GPS's for years in other outdoor activaties and they have always seemed to to their job. Myself and friend were out looking for a local cache. When we got to the immediate area of the cache site there was a distint differance in the two models accuracy. I was using my Megallan Sportrax Map(lastest flash) and my friend was using his Explorist 400. His GPS put him appox 16 ft from the site while mine was bout 40-60ft. SO i guess my question is was just a signal issue or are new models that much more accurate? Thank Quote Link to comment
+briansnat Posted January 28, 2006 Share Posted January 28, 2006 Not necessarily. You could go back there a day later and your results could be reversed. Quote Link to comment

+briansnat Posted January 28, 2006 Share Posted January 28, 2006 First off you don't know how accurate the coordinates of the cache were. Its possible the cache owner's coordinates were off and your GPS was actually the more accurate one. Quote Link to comment
+StarBrand Posted January 28, 2006 Share Posted January 28, 2006 The more GPSr you have the more different readings you will get. I know - I have 4 Garmins and have seen it many times. They are close but no 2 seem to ever agree. Quote Link to comment

I hope you're just messing around? If not because I am not sure were you from "fluke" is another term for "it just happened for some reason" Quote Link to comment

+Prime Suspect Posted January 29, 2006 Share Posted January 29, 2006 Ok ..so dont worry bout it on my part? That's right. Since they're both Magellans, you can just assume they're both wrong, and not worry about it. Quote Link to comment
dbowers Posted January 29, 2006 Author Share Posted January 29, 2006 I think I figured out what was goin on. We had two different map datums; my friend was using WGS84 and I was using NAD27. Quote Link to comment
+budd-rdc Posted January 30, 2006 Share Posted January 30, 2006 I think I figured out what was goin on. We had two different map datums; my friend was using WGS84 and I was using NAD27. Glad you figured it out on your own. If you are methodical and observant enough, it is possible to make the coordinates of two different GPSr's (regardless of make) match within 0.001 minutes. This depends on the environment you are in, of course - for example, tough to do this in deep forest cover. This is very important when you hide a cache, to obtain good coordinates. There are cachers in my area who consistenly post good coordinates on their hides, so I don't think this is luck. Quote Link to comment
+The Canning Clan Posted January 30, 2006 Share Posted January 30, 2006 I have an Etrex and an ETREX Legend C...we hunted a cache with them side by side and they were quite a bit different, next one we tried they were bang on to each other Quote Link to comment
