I went and dug out my $16.00 Marbles (from Countycomm last year) pin-on compass and I have got to say that you are right on the money. It had a huge bubble which was not there when I was hunting with it last year. I turned it over and the bubble disappeared--and it began to point TRUE SOUTHWEST. I turned it over a few times, the bubble reappeared, and it began to point North again.

It's crap--no offense to the Moderator but that's what it is.

I thought Marbles was a good-maybe the best-compass. Now I'm going to try out the Tru-Nord or maybe the SAS.

I'm also going to drill a 1/32" hole in the cover and drain the fluid out of it. Maybe it will work halfway decently as a dry compass.

My question is this: is there some great scientific obstacle to overcome before sombody can manufacture a magnetic mini-compass that will actually point to magnetic North instead of non-magnetic Southwest? One that doesn't require a person paying $50.00 for it? I'd really like to know.
