Star Finder 2102-D vs Sextant

[Seas the Day]

I've used a sextant around 20 years ago and am considering re-acquainting myself by buying a new one for upcoming cruising. Over the last few days I've come across information on the 2102 Star Finder and related book by David Burch. Is this an alternative to the sextant or a useful aid?

Many thanks in advance for your advice(s).

Useful aid.....

The 2102-D is the US equivalent of the British NP323.... helps to identify stars..is all..

From somewhere in cyberspace....

'British Admiralty NP323 Star Finder and Identifier, 1958 Edition
Consisting of a Star Chart (Northern and Southern Hemispheres) and eight transparent templates. (Latitudes 0, 10, 20, 30, 40, 50, 60, 75 degrees). The Star Chart shows the 57 stars tabulated in the Nautical Almanac. To use you first find the LHA of Aries, select the plate nearest your Latitude, align an arrow on the template with the LHA of Aries. From the template you can then read off the approximate altitude and azimuth of any selected star, or identify a star for which the altitude or azimuth is known.'

A handy item to own ...
