  • 20-mm liquid filled button compass compared to a US penny.  I sprinkle these compasses amongst my gear and clothing to be sure I can always find the direction back to my vehicle or trail head.
  • A robust little compass - the same compass we manufacture into our FireSteel Tubes
  • Side view of our 20-mm liquid filled button compass
  • These are HIGH QUALITY button compasses.  Beware- many button compasses are cheaply made and very inaccurate.  If you are going to carry a button compass, it probably should point in the right direction!


Our 20mm button compasses are filled with a clear liquid that dampens the compass needle which helps to keep it steady and free floating.

About as big around as a United States penny, the liquid filled 20mm button compasses have a luminous dial, take up little space and are excellent for survival kits.

Sprinkle these compasses amongst your gear - you may be very glad you did.  Save yourself from getting lost or find your way out of the wilderness, you cannot go wrong by having some button compasses handy.

Each compass is personally checked by me against a very accurate land surveying compass (I was a land surveyor in the Great North Woods for much of my life).

Note that the liquid in the compass may freeze at temperatures lower than -10 degrees F (-23C). If you expect to be using your compass in colder conditions you may be better off purchasing the non-liquid filled button compasses.
