I have a Davis Mark 15 that I would sell to you for $50.00 plus shipping. It is in excellent condition, with its plastic case. This model has been used for circumnavigations and Atlantic crossings, as an attestation to its accuracy and functionality. Let me know if interested.

The dancing bubble issue can be mostly mitigated on land by either hanging the sextant from a branch using a taut-line hitch, or by setting it atop a relatively level rock, ledge, or stump. I’ve gotten with a few miles using an A-10 or a Mark IX this way, even without an averager.March 15, 2021 at 10:18 am #10423
When I was a kid, I read several novels by the Australian author Neville Shute about his experience as a bomber navigator in WWII. It seemed like a miracle to me that they could fly above the cloud cover in the dead of night and determine a reasonably accurate position with a 3 lb. hand-held device and a book of tables. Then in 1976 I found a functional air sextant and a Rude star finder at a camera store – the owners didn’t know what they were, and let me have it all for $15.00. I still use them, today. The hook was set!
