I am Jeff in NC. I will use the two compasses to teach my granddaughters, ages 8 and 10, to use just as I taught their mother many years ago. I used a nearly identical compass as a boy scout in the 1970's. I have found online tutorials and lessons specifically for children. They will learn the basics at the kitchen table before walking several 3 point outdoor courses. Each course has a treat treasure at the end to make it fun. I will have the joy of time alone with them as I teach a science lesson. The capabilities of this compass are far beyond what they need now but ideal for future wilderness hiking. These girls will even make a simple compass by magnetizing a straight pin to place on a cork disk in a bowl of water. I have done it and the pin rotates to point north even when forced to point any other direction. I was very surprised to purchase these instruments for just $10 each - I expected to pay $30. All you grandpas jump on this opportunity for priceless one on one time with the grandkids. Once they learn orienteering they will impress the pants off their parents!
My wife took an orienteering class through CERT and bought a Wally-World compass on her way to the class. The compass was useless, and she ended up borrowing one from the instructor to complete the course. I, having taught orienteering in the Boy Scouts, got this one for her and turned her loose on a topographic map at our local, wooded park. She quickly used the compass to find and hike to several shelters, a playground, and the pool. Pulled out a NOAA chart at home and she plotted our way points and headings to sail in Charlotte Harbor next week (I use a chart plotter but always carry paper charts. I plan teach her about map Geo-Caching (with my GPS as a backup) soon.
