Very simple to use and \nvery very cheap now on the used market. It's OLD technology but I don't \nthink anyone will fault you for using it even if it isn't as accurate. \nIt'll get you close enough and to me as long as it shows the grid that \nyou are passing out on the screen then you've made a \"good faith\" effort \nto do things right.\n\nBTW: Nice to work you on SO-50 the other night. QSL will be in the mail.\n\n73 Matt\nW5LL\n\nOn 9/2/2010 8:27 AM, Zachary Beougher wrote:\n> What is this 'GPSMAP76S'??? If I am understanding correctly, it plots grids\n> on the GPS screen?
