    Thank you for the welcome.
    I do have a question about using the horizon on the frozen ocean. Does having four feet of ice over the surface of the ocean affect the accuracy of a shot?

    I also wonder if anyone knows how long the database in the Celesticomp V is good for?

    Thanks ahead of time!
