SnipeHunterBot Posted April 18, 2005 Share Posted April 18, 2005 All of the sudden my rhino 120 isn't so accurate. I used it to for geocaching yesterday and was all over the place. We ran into a couple other cachers in and they were nearly dead on accuracte with a 60c. Any ideas on what could be going on, or better yet, how to solve the problem?? Quote Link to comment
+JohnnyVegas Posted April 18, 2005 Share Posted April 18, 2005 How far off was it? how strong are the batteries? weak batteries can be a problem. Quote Link to comment
+Prime Suspect Posted April 18, 2005 Share Posted April 18, 2005 Garmins have special circuitry in them, that can detect the presence of another Garmin unit nearby. It can then query that unit's specs. If it's a newer or more expensive model, the GPS will start downgrading its own performance, making the newer/more expensive model appear to be better than yours.

SnipeHunterBot Posted April 18, 2005 Author Share Posted April 18, 2005 new batteries but there were other units in the area. I was standing side by side with the guy holding a 60cs. A few other times, I didn't see anyone near us with a GPS. There were a ton of rock formations and things near us, which I have heard can contain a magnetic force, but I'm not sure if that would screw with a GPS or not. Quote Link to comment

+TresOkies Posted April 19, 2005 Share Posted April 19, 2005 Were there any Magellans around? Maybe it didn't want to embarrass them by being too accurate... Quote Link to comment
SnipeHunterBot Posted April 19, 2005 Author Share Posted April 19, 2005 it was off by around 50 feet. The main issue was that it would say I was within a few feet and the next second say i was 100 feet away. It would never really settle Quote Link to comment
+JohnnyVegas Posted April 19, 2005 Share Posted April 19, 2005 If it was only happening at one cache, and if the cache was next to the rockformation the GPS signal could have been bouncing off of the rocks if it was a large enough formation, I have had this happen to me when I was looking for a cache that was at the base of a large building, as I would get close the the building the GPS suddenly point to a point about 100 feet or more behind me.

+GeoMom Posted April 19, 2005 Share Posted April 19, 2005 I Have a Rino 120 as well. It has been kinda of loony lately too. I'm chalking it up to my inexperience. My son is coming home from college next week. I'm going to have him take a look at it and compare it to his Rino. His is the next step up - a 130? Quote Link to comment
+Circle of Confusion Posted April 20, 2005 Share Posted April 20, 2005 Do you have WAAS on? I find that it has a negitive effect on my accuracy if there are high hills or trees around, which is pretty much everywhere where I live. I keep it off. Quote Link to comment

I find that it has a negitive effect on my accuracy if there are high hills or trees around, which is pretty much everywhere where I live. I keep it off. WAAS does not have a negitive effect on my accuracy. This is a myth, the key to WAAS is that the GPS has to run for at least 15 minutes in order to build up an almanac of data to make the proper corrections. I have had WAAS running on all my GPSr and have never had a problem with accuracy. WAAS Quote Link to comment
