&gt; Most of the sextants you can get on eBay these days are just for decoration, however.<p>Ugh, these things are a plague. There&#x27;s a factory in India pumping out most of these. They do a whole bunch of variations, boxes, antiquing, etc. Some sellers on eBay list them as genuine antique instruments, which is straight up deception.<p>The replicas of box sextants (small pocket instruments in the shape of a round box) are especially hard to spot if the seller is dishonest.
