The exhibits are allocated to ten* different categories depending on their function. To visit a specialised department, just click on the picture of the relevant category. You can also use on all pages the pull-down menu button COMPASS TYPES. Clicking on the button SEARCH will lead you to the instruments via the manufacturers' names or technical words (example: miner's compass). The five chapters under MISCELLANEOUS are also being completed on a weekly basis.

* The pin-on lapel compasses are displayed together with the wrist compasses because of their very limited occcurrence.

Dear visitors,
This museum is not meant as a simple exhibition of antiques but pretends to give an overall picture of the technology being gradually replaced by satellite navigation systems. We thank all those who steadily help building up what is becoming the largest reference data base worldwide for all sorts of compasses, by sending us pictures and/or technical and historical information.
