Well, I have a Silva Model 426, and it has a bubble. However, the compass still points North in relation to my front door. Is it still useful, or chuck it? Let me know.
OH YEAH. The tritium compasses are supposed to be REALLY nice. Dear santa... haha.I've got a Silva compass with a bubble too, had it for years and have used it in a land nav course for law enforcement at the NAS in Meridian, MS in 2000. It worked as well as the G.I. issue some of the other guys were using....the tritium is nice on those G.I. compasses for night use, but they're awful proud of them.
Very helpful info! Thanks a ton!!!I have an old vietnam-era G.I. compass in excellent condition. It has the air bubble....
I was taught (by retired Army) the compass must be held so the air bubble is dead center in the glass - that is the only way the needle will be centered and level on the "jewel".
So, if you have a good-quality liquid filled compass, it WILL have the air bubble, factory installed. Just make sure it is in the center of the glass when using it.
