Ball and Chain is a shallow outer-reef site off Key West where coral structure and open blue-water edges make it a classic boat dive on the Lower Keys reef tract. It is best on calm days, when divers can cruise the reef comfortably and watch for passing turtles, rays, sharks, and schools of reef fish along the coral ridges.
