About This Item

JohnnyM.'s Sextant Geocoin

The octant and sextant replaced most of the earlier navigation tools in the late 1700s such as the back staff, mariner's astrolabe, and quadrant. The octant is 1/8 of a circle and a sextant is 1/6 of a circle. The sextant allowed for more range in the degree scale over the octant.

The biggest improvement the sextant made over all other sighting tools (except the octant) is its double reflecting mirrors which eliminated the ocular parallax other tools caused. It also allowed for greater accuracy by having finer degree adjustments.

The sextant design is so universal and accurate that it is still used on ships today as a backup instrument to electrical navigation devices. Even aircraft used these as backups if their avionic systems failed.

Moin,

diesen Reisenden konnte ich in den letzten Monaten aber vor allem im Mai 2022 entdecken und discovern 😆
und gesehen habe ich den TB/Coin oder deren Nummer...in Dosen, auf Events, im Netz, in Logbüchern, in Labs, in Logs, in Listings, in Checkern, auf Fotos, an Autos an Fahrrädern....oder sonst irgendwo drin oder dran 😊

Danke für's zeigen und eine gute Weiterreise....😎

...und den Ownern und uns Cachern wünsche ich (...in dieser schwierigen Zeit durch das blöde Corona Virus und den Krieg in der Ukraine 🤢)...

....Alles Gute 🍺🥂🍹☕🍰🍔🍕🍩🍦,....haltet durch, passt auf euch auf, habt ein schönes 2022 und bleibt vor allem gesund! 👍

LG Trek...😆 aus "Marzipancity" 😎
