First, I pre-adjusted my sextant to be close to the expected Hs. Then I looked at my watch and noted time to the second. Then I simply started counting one-one hundred, two-two hundred, ... while I adjusted my sextant to its final reading. Then noted time and reading in my notebook. With this method, you should be able to get a sextant reading within 15 to 20 seconds of starting counting. I did a few trial runs of simply my time counting to make sure I wasn't counting too fast or slow. I believe that even after 30 seconds I was within one second or less. I was taking sights from a known position and my readings were no less accurate than what I got when using a helper on previous expeditions.
