As long as I've been geocaching, I've used the app on my iPhone. Trying to guide my Girls Scout thru Geocache badge & need to teach them to use a handheld GPS. I bought a used Magellan Triton 200. I have gotten the manual online. But, I've been fiddling with it all day and cannot figure out how to put in coordinates (It won't let me insert a (.) where I want, I can't find out to place the degree symbol, etc. Is there a local (Columbia SC) who knows this little unit who can walk me thru? Or meet me in person and I'll buy you a beer as compensation for a little tutoring :-)
