Thanks all for the info. Just like other Magellans was correct. I followed the instruction from the forum here and it worked .Funny how those instructons are not in the manual. I tested it out and would have found my first cach except for the mosquitos. I will return to complete it after getting some repellant.
This Explorist seems to be a good working unit. Worked in the car, in thick trees and updated quickly as long as I was moving. Just making mistakes with the compass. Something else to learn now.
