- Towboard abstract "A towboard is a piece of aquatic survey equipment consisting of a board attached to a rope that is towed by a surface vessel. It is used to tow one or more divers underwater at a constant depth to survey bottom features such as coral reefs. The diver may use a scuba set, or if only a snorkel, may remain at the surface, or travel underwater for around two minutes.The surface vessels travels at approximately 1 to 2 miles per hour and may tow two divers, one with a camera pointing down, and other with a camera facing forward. by a surface craft. The boat follows a depth contour to keep the towboard over a specific depth. The divers can also maneuver the board to maintain a more precise depth and avoid obstacles. A survey may cover about 2 miles over a period of around 50 minutes.This type of surveying method is called a towboard survey, towed-diver survey, and the manta tow technique, the latter named after the Manta Board, an oval towboard marketed for recreational use. A variant is the SAM or \"Single-armed Manta-board\". This consists of a small board with a strap to secure and tow the diver by the forearm. This frees the other arm, allowing the diver to take notes on a pad held by the towing arm.The use of a towboard is considered safe up to approximately 90 feet. Beyond that, the divers would require decompression.Towboards may be equipped with a GPS and sensors to record the temperature and depth every few seconds.".
