I need to locate a property marker in the ground. The survey company used NAD 83 North Zone MO to do it. I have tried converters and stuff but it never puts me remotely close (ocean or India). Anyone know much about this? I know its fairly an old type. I just need this translated into something a phone app or XT (tried all the stuff in my XT) could nav to like with Min, Sec. N:1076198.54 E:2827640.17 Any help would be much appreciated!! Thanks guys!
