I also found one for a few bucks in a junk shop.they thought it was an odd barometer. Mine is of a different design (newer maybe), without knob and with barometric pressure readouts also. I bought one of mine in the 80's for over $200. You can also use the altimeter as a baramoter. Your GPS altitude is not that accurate +/- 100 feet it depends upon the satellite constilation. Or let you know your at the right spot on a map. For Navigation it can help if you want to follow a contour line. The know lets you adjust the dial to what the relative altitude is. Know the altitude of varies land marks, find bench marks. When you go out look for signs with altitude on them. Altimeters work on barometric pressure so you can loss or gain a 100 feet as a storm front moves trhoug, the sun comes up and warms up the air.

Use to follow contour lines, as a second or third point in locating position on a map. Reset to known altitude before leaving camp. Reset needle with knob at every KNOWN altitude to recalibrate for atmospheric changes.Īt camp in evening note altitude.changes in morning indicate atmospheric changes.higher pressure system comes in, camp decreased in altitude.lower pressure system-camp gained e to predict weather for day. Around again, a 6 in window etc.probably to 15000 ft.maybe to 21000 ft depending on model. Once around the small window will have a 3 in it and needle will be at 0. If you know your altitude you can set your needle to it and as the needle then moves up or down from that elevation you can see the changes in air pressure thus giving you some data about current weather, track this and you can see trends in the weather, watch the clouds precipitation, and wind and you can get pretty good with 6 to 12 hour forecasts. Any information would be greatly appreciated! Well I dug around a little bit and I have the original box and papers, I'll see If I can find my pamphlet thing I've got too. There are no markings anywhere on the sides or back of the altimeter. The case of the altimeter itself is black metal, with a single knurled knob on the top. It sits in a leather pocket case, face shows maximum altitude of 3000meters, with a window showing altitude in feet. I've exhausted all the Google Fu I can muster and have to come any closer than when I started. I bought this old altimeter at an estate sale a while back and I'm trying to find information on it.
