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.

Über die letzten paar Monate sind nun allerhand TBs zusmmen gekommen, die es zu discovern gilt. Ob auf Events, an Autos, bei Instagram. Immer wieder sieht man diese kleinen Codes :-D

Nun werden alle Bilder aber mal ordentlich ausgemistet !

LG axlemaxle vom team_alpaka :-)
