why the merchant navy
Why were these instruments so popular in the merchant navy, because I have had several that had been used in the merchant navy with post-war certificates?
This sextant was also used in the merchant navy from 1946.
Every ship owner provided his ships with sextants, but they were relatively heavy and had small mirrors, which was often an inexpensive and standard instrument.
The German Kriegsmarine drum sextant had larger mirrors, giving you a much brighter and larger field of view, making it easier to find the celestial bodies.
The filters assisted in the view of the sun and reduced the effects of nebulae and fog, often using a combination of these filters.
It was a very user-friendly instrument; the light aluminum ladder frame was much less tiring with long use, your hand vibrated less if you had to hold the instrument up for a long time,
it was also easier to keep the sextant stationary in strong winds on deck, so you could fine tune the micrometer drum.
