+Labrador Wild Man Posted August 8, 2014 Share Posted August 8, 2014 Hi all Need some help I will try and explain need to use my Garmin 62st with a map which will be set for Nad27 But at the same time there is three high geocaches on the mountains and are in WSG87 If I download the caches has normal and my gps is set to WSG87 Then change the gps to Nad27 for my hike and my waypoints which be set in Nad27 If I decide to go for the caches, do I just change the datum back to WSG87 And the caches should show in to WSG87? Do I understand it right or not? Any help would be great Thanks LWM Quote Link to comment

+Red90 Posted August 8, 2014 Share Posted August 8, 2014 As long as you load the caches by computer, you can go ahead and find them with the unit in any datum. It only matters if you are manually entering coordinates. Quote Link to comment
+Viajero Perdido Posted August 8, 2014 Share Posted August 8, 2014 You meant WGS84, right? That's what our game uses; see fine print at bottom of any cache page. To expand on what Red90 said, if you're manually entering coords off the map, you need to switch the unit to the map's datum before entering the coords. Then ASAP afterwards, you should reset it to WGS84 before you forget. (Hiding a cache later when it's still on NAD27 leads to unhappy would-be-finders.) Quote Link to comment
+Labrador Wild Man Posted August 9, 2014 Author Share Posted August 9, 2014 Big thanks a great help will load caches has normal then chnage to NAD27 to work with my map these cahea are 3000 feet up just hope i can find them when i get up to them thanks LWM Quote Link to comment
xyzee Posted August 13, 2014 Share Posted August 13, 2014 Don't the later models have a dual display feature like on the 60 series? On a 60Cx, I can view both the WGS, and the NAD 27, at the same time at the bottom of the Trip Computer Page. I put the Location (lat/lon), which is always in WGS, in the top Wide Data Field. Then the Location (selected), in this case NAD 27, in the bottom Wide Data Field. This also works on other Pages that offer 2 Wide Data Fields, like on the Map Page. Also having them in the Big Numbers on the Trip Computer Page, is a big help to me. This can help one from having to do a lot of switch-a-roos. Quote Link to comment
Forkeye Posted August 14, 2014 Share Posted August 14, 2014 (edited) Lat. and Long. on a paper map would be in the same datum as the UTM or any other grid that your map or chart uses/shows. I have lots of older Canadian maps that are Nad. 27 that show both co-ordinate systems. Made long before WGS84. Lat.and Long. on your gps still does not automatically use or default to WGS84 you still need to set your gps to that datum, WGS84 for geocaching. You still are able to set your gps to show Lat. and Long. in one field and some other grid in another field or box if you chose. Edited August 14, 2014 by Forkeye Quote Link to comment
