+Finger Posted April 15, 2002 Posted April 15, 2002 What has everybody found as the preffered (Best or correct) setting for the Garmin eTtrex range. What is the difference in distance between the 2 settings and how much distance does the last didgit refer to ?? Regards, Finger (UK Charter Member) Quote

I have tended to keep mine on Grid, especially when the GPS is being run in OSGB co-ordinates. Aside from that I don't change it, unless there is a cache such as SP1 that requires a waypoint to be projected in a specific direction. Richard Quote
JasonW Posted April 15, 2002 Posted April 15, 2002 Depends on what you're using it with.... If it's in conjunction with a traditional compass, then magnetic makes sense. If it's with a map then grid or true makes sense (depending on the map) If you're Moss Trooper you'll have a mental map of the variance in magnetic declination across the globe (correct to within 0.5 degrees) and you'll set it to true just to prove a point Quote

+Finger Posted April 15, 2002 Author Posted April 15, 2002 Thanks for your comments , BUT (Why is there always a but ??) With Magnetic & True I get slightly different lat & long readings. Garmin have told me that this is normal & correct, But what does everyone use for Geocaching as I want to give as accurate as posible location. Regards, Finger (UK Charter Member) Quote
+mdshamilton Posted April 16, 2002 Posted April 16, 2002 This is stretching back to my Boy Scout days.... The UK is relatively far north. The further north you get the bigger the difference between magnetic and true north. Therefore I tend to use true north on my GPS. Mark, Matthew & Christopher We'll get there eventually.... Quote

+jeremyp Posted April 22, 2002 Posted April 22, 2002 I was browsing the Garmin web site looking for the 2.26 firmware upgrade and I stumbled upon the Vista specification. The stated accuracy of the magnetic compass is ±5 degrees. If I remember correctly, mag north is about 4 degrees away from true North in this neck of the globe. This pretty much makes it irrelevant which one you use. I've left mine set to the default of true North. ------- jeremyp The second ten million caches were the worst too. Quote
