Charles,
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.
Stan

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!
