Re: Question for the Cel Nav Pros

Capta, you are right about the calibration. Ive calibrated it and it was pretty far off.

As for the debate of dip correction, I have answers. I was able to find and download the directions for this Bubble Horizon from the manufacturer. Turns out -drum roll- "A bubble horizon does not require a height of eye correction". Good and bad news for me. It means my first sight was total dog doo. But semi good news, I need to figure out a Bubble Correction which I did not factor in. It says the BC is normally less than 15 minutes of correction. The process looks like kind of a PITA but I dont have much choice.

EDIT: The Bubble Correction involves taking a few shots from a known position and averaging the error. Or, sighting the actual horizon, subtracting dip, and reading the index. Thats the Bubble Correction. I wish I had a real horizon :-(

Ill update later. Thanks all for the comments and links. And keep'em coming.
