    Agree with you Sam, with PDFs is no so user friendly, but it works for consultation.

    I have the book by our college in NavList Bill Morris http://sextantbook.com/, I bought the kindle version and as is a native format for kindle, is great top read and to see the illustrations. You can also use the desktop app to read it on a bigger screen,

    I usually read when I go to bed, when traveling, and when sailing. In my last route with my sloop, i forgot my kindle, the wind was only force 2, a fantastic situation to enjoy at sea with a goog reading. And What did I do? I took my Davis plastic sextant, the only one I have always aboard, and practiced the DR Doniol-Hanno method. With a cold beer and the pencil, it was a pleasure, only one LoP by Sun altitude. Then I took my  bearing compass and by tree bearings I obtained a fix by two horizontal angles. The fix was plotted on the nautical chart, and for my surprise the error between the coastal fix and the MSH LoP was unacceptable.
    I turned on the GPS, and wrote the position.
    At home I checked my calculations, the haversine SR was OK, and the cross error between the LoP and the GPS position was less than 2.5 nm.
    For bearings,I use a Hockey Puck, vion mini morin 2000, the problem was that now the error of the Hockey Puck is 12.5º, (tested on land with three different targets. from different places). Before this it was 1/2º accurate, it passed all the winter in the same place, but i think there are no magnetic fields ???

    experiences about your
    Hockey Puck accuracy?
    I want to hear about this issue, better in another subject

    regards,
