    Welcome to the group Charles,
    To add to what Greg said, the distance of the horizon depends on your height of eye.  The higher you are, the more distant the horizon needs to be.  From a sail boat or shore, it isn't much distance.
    I prefer to use the sun or stars to check index error as it is easier for me.

    A distant shore of two miles or more is good enough for checking index error (height of eye of 4 ft.). Remember if your index error is on the arc subtract and if it is off the arc add. Try using a star and line the two images up. A little bit of side error is ok.
