I guess I should ask you what your idea of a long trip is, and how this GPS might be particularly good for that sort of trip. I am only asking because you made a pretty enthusiastic endorsement, but also a pretty vague one, and it would mean more to anyone reading it if they knew what it was based on.
I use that Garmin. I like its AA battery use. It weighs about 4.5oz w/ lithiums. Their posted weight is probably with alkalines. It takes about 40 seconds for the first power up, and then about 10s after that. I take it on trips where Iíve never been. And each time, Iím glad I had it. Last month we were doing some of the River to River trail in southern IL. There are so many trails going through there that we couldnít tell which one to be on w/o a GPS since signage is lacking. Also a lot of the trails arenít on the USGS map, so itís nice to know where you are on the map w/ that Garmin.
I bought the eTrex a year and a half ago, and found out it says I am about 250 meters north of where I really am. Is there a way to calibrate it? I figured out the discrepancy by taking readings at road intersections and comparing them to the topo map.
Since the etrex H is accurate to 10m, it sounds like something else is amiss. Did the map maker put the roads in the correct spot or did they fudge it a little? Are you in the middle of several high rises?
Probably the GPS is accurate and whatever you compare it to is off. I've seen this before between Topo 4, Google Earth, and a printed map.The GPS only recieves timing signals, its hard for it to be off. Jim
