| Anyone have a liquid filled compass freeze on them? |
| When I took my test for the Expert Field Medic Badge some years ago, the temperatures were in the negative digits the day of the land navigation test. (This was in Germany.) I had no trouble with my issue lensatic compass. It was in my hand, exposed to the elements for quite some time as I navigated my way through the course. |
| Funny you should mention this. I was teaching Land Nav to some folks this weekend, and they had the cheapo Wal-Mart Liquid filled compasses. After a couple hours of temps in the single digits, they were frozen stuck. Fortunately, my GI compass was still functional and saved the day. |

This is the compass I bet my life on. Tru-Nord It is not liquid filled and I've never had one lead me astray. |

All Whiskey comments aside I really haven't seen one freeze. Always had good middle range name brand ones. Now I know my username says FL but my compass malfunctioned!! Had em out in all kinds of ski related situations and never seen it. Temps all over the place. sometimes compass in a pack , sometimes on it or in pocket when not in use. Gettin to thinkin tho......... Good heads up on the el cheapos freezing here. I have a few friends that pack lousy ones - I'll tell them. I end up replacing mine often cause I head out with people on short hikes sometimes and they have nothing! So I usually carry a copied map and one of those "decent" compass' and just let them keep them- If they're friends they get the first pitcher! Thanks for the link to that simple little compass - looks intersting. -JC |
It looks a lot like the Marble's. Marble's Compass |

Brrrrrr. Where's that whiskey again? I asked this question to some full-time ski patroller friends. None had ever seen one freeze. And they all carry at least one. I can't wait to get back to some cold weather and soft snow and try to freeze my compass - and keep the whiskey unfrozen!!!!  JC |

does the liquid ever "evaporate" from the plastic compasses? i have a couple that are many years old and the bubble seems bigger than i recalled originally, but i can't really say for sure. would it even matter? i think not. ..just something that pops into my head from time to time. |
