All good, just took a while. I have a full tank of water again and all the hoses are drained properly. Above freezing temperatures coming in a few days, I can't wait .
My first guess was to say it’s a compass but the numbers on the dial aren’t set up like one. Temperature gauge? Wind speed indicator? Blood pressure gauge? Propane tank pressure meter?
Interesting……I spent 6 years setting up timber sales, marking plots of land and estimating timber volumes for the US Forest Service in Wisconsin and the Ozarks. Used a field compass almost everyday. This is by far the most complex compass/ instrument I ever saw. In college I took field surveying classes and worked part time for a land surveyor and anything even remotely this complex would be something we lugged around on a tripod…..cutting brush and vegetation to insure accurate lines of sight.
