    That paragraph applies to any kind of bubble horizon.

    I have one of those practice bubble horizons.  I hope you do better with it than I did.

    Subject: [NavList] Practice Horizon Bubble

    Quick question regarding use of Celestaire practice bubble.  Purchased one of these to practice with due to the lack of a readily available shoreline.  In the Nautical Almanac, in the table for moon altitude corrections, noticed a small paragraph in the lower right, stating that if you use a bubble horizon, you should neglect the dip correction and subtract 15' for your reading.  My queston is,would this apply to this particular practice bubble horizon, or is this for a more sophisticated bubble type horizon.  Apologies if this question has been asked before.  thanks!
