The Airguide Co. went through several buy-outs since it's founding in 1930, the most recent in 1996.

I have already made contact with Johnson Outdoors to see if they can help.
(Hi! td
) twinkiedooter's link is correct in saying it's a matter of turning the set hand to the right altitude. to make the adjustment.
Do you know your elevation above Sea Level?
Third link down in "What do you want to do"?
EarthTools - Find places, latitude/longitude, sunrise/sunset, elevation, local time and time zones
Once you zero in on your location, move the map to under the "cross".
Wait for calculation at left.
