discboy321 Posted February 24, 2003 Share Posted February 24, 2003 Is there a GPS that is accurate to within a couple of feet or even inches ? I currently have a Lowrance 100 and only get about down to 35 feet . Any info on any other gps would be great. Ed Quote Link to comment
+apersson850 Posted February 24, 2003 Share Posted February 24, 2003 There are professional units, that can give you millimeter accuracy. However, they cost a lot, are heavy and require rather long time on the same spot to complete the measurement. Search for Trimble, for example. Anders Quote Link to comment
+DustyJacket Posted February 24, 2003 Share Posted February 24, 2003 Another thought: You might have a GPS that is accurate to the mm, but you are still looking for a coordinate that was created by a less accurate GPS. So, once again you have to search. My Meridian Color is sometimes right on, sometimes 20 feet off, and in one case was over 50 feet off. Was it my GPS? The other GPS units? Or both? I still found the targets though, through observation and a couple of good guesses. DustyJacket ...If life was fair, a banana split would cure cancer. Quote Link to comment
+fairplay Posted February 24, 2003 Share Posted February 24, 2003 For example, this week-end I lost nearly one hour, desperately searching for a cache. Since I was very close to the indicated location, the GPS constantly told me to move. In a last effort I looked around the area and finally found it. So your GPS is good to give you an idea where to search, but the last meters have to bee made BY YOUR EYES AND YOUR FEELINGS !! hello Quote Link to comment
+SpongeRob Posted February 24, 2003 Share Posted February 24, 2003 I try not to use the GPS as the end all in navigation. Using your head works as well. Think of this. You walk the last 100 feet generally in a straight line. The GPS knows that your walking right towards the target. In fact, it's got the last 100 feet to keep a lock on you and your destination. When I walk the last 100-200 feet to the cache I pay close attention to where I'm headed to (looking ahead instead of at the GPS countdown). Many times this can lead me right to the location without having to walk in circles. Your GPS is going to be much more innacurate once you stop and start (walking in circle effect). I find that just walking 50 or 60 feet can get you back on a steady lock. -- SpongeRob rwmech@keenpeople.com www.keenpeople.com WPWU826 Cache'n Retrievers Quote Link to comment
+Brian - Team A.I. Posted February 24, 2003 Share Posted February 24, 2003 My eTrex Vista has been as close as 8' accuracy, and that being without a WAAS lock. But when you're in a fairly open area, anything <30' accuracy is going to get your pretty close to your objective. Brian Team A.I. Quote Link to comment
+Roadster Posted February 24, 2003 Share Posted February 24, 2003 On my second cache hunt my GPS (Meridian Gold) said One Foot and pointed to the right of me and I looked down on the ground to the right of me and about a foot and a half away I could see the blue of the cache under the thick grass. One thing was: this was in the wide open no trees no cliffs, nothing but open grassland. One of those things I bet will never happen again, but I thought "dadgum! I love this GPSr!" I call it beginners luck! How many of you believe in telekinesis? Raise my hand... Quote Link to comment
Kerry. Posted February 24, 2003 Share Posted February 24, 2003 Yes, but they are a little bit more sophiscated than what one pays a few hundred $$'s for. Cheers, Kerry. I never get lost everybody keeps telling me where to go Quote Link to comment

max2extreme Posted February 25, 2003 Share Posted February 25, 2003 Mine's a Magellan and its accurate up to 3 meters. Check out ebay. Always lots on there. Good luck. Quote Link to comment

Price is about $10,000. 2cm accuracy does need a little clarification as that's not basically possible from one "single receiver" but more a "system" and depending on the "type" of operation.

True. It's basically a surveying system. It uses 2 antennas on tripods. Used for doing crash reconstruction. Quote Link to comment
