Rope Signals
These are generally used in conditions of low visibility where a diver is connected to another person, either another diver or a tender on the surface, by a rope. These date back to the time of the use of Standard diving dress. Some of these signals, or pre-arranged variants, can be used with a surface marker buoy. The diver pulls down on the buoy line to make the buoy bob in an equivalent pattern to the rope signal.

Famous quotes containing the words rope and/or signals:
“Rather would I have the love songs of romantic ages, rather Don Juan and Madame Venus, rather an elopement by ladder and rope on a moonlight night, followed by the father’s curse, mother’s moans, and the moral comments of neighbors, than correctness and propriety measured by yardsticks.”
—Emma Goldman (1869–1940)
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
