Alan,
Chasing Shackleton was on at 10 PM, and I've heard things that surprised me on TV even earlier, and on non-pay channels.
The Davis sextants work surprisingly well. Just have to let them stabilize to the temperature and check index error before and after a run of sights (and correct accordingly). A lot of students, particularly women, like them because of their light weight, at least until the wind picks up. Yes, the scope leaves something to be desired.
I went to check on the cardboard sextant a while ago. The glue I used dried up and the thing had fallen apart. I put it back together, but with hot glue this time. Much better. The 7 nm sight I took with it was from the front deck of a 25-foot boat anchored at Duck Island in Long Island Sound. It is a very popular spot, with boats constantly going in and out of the anchorage, and boats moving fast not too far away. I was getting bounced around quite a bit, and I really think most of the error was due to that, not to the sextant itself.

Stan:
Re "prime time", this broadcast was NOT in that interval, or was it?
Re sextants,I have a Davis Mk. 15, that I purchased via Ebay, a number of years back. It works, though it does seem sensitive to grip pressure, and seems to feature wandering index error. It's optics are less than sterling, but useable , and if dropped over the side, I guess it would float too.
The fix you got with that cardboard kit sounds quite good, considering conditions an equipment.
