I like the way this compass can be mounted on either a horizontal (over or under) or vertical surface. It can take a substantial inclination (as on a sailboat) before it gets pinned. The dial is large enough for me to see from about four feet away. In a pinch, it can be used as a handheld bearing compass, although sighting over the lubber line involves a little visual estimating. On the downside, there is no built-in provision for compensating, but then this is not intended to get you across the ocean. I would recommend this compass to a recreational boater.
