In order to enhance the divers to be more freedom of movement under the water, a good Fins blade is very important. The fins have a large blade area and divers use the more powerful leg muscles, so are much more efficient for propulsion and maneuvering thrust than arm and hand movements, but require skill to provide fine control.
Protection from heat loss in cold water is usually provided by wet suits or dry suits. These also provide protection from sunburn, abrasion and stings from some marine organisms. Where thermal insulation is not important, Lycra suits/diving skins may be sufficient.
For the safety diving, divers must monitor the depth and duration of a dive to avoid decompression sickness at all time. This can be done by using electronic dive computers. Beside that, divers usually need a compass to navigate.
Cutting tools such as knives, line cutters or shears are often carried by divers to cut loose from entanglement in nets or lines. A surface marker buoy on a line held by the diver indicates the position of the diver to the surface personnel.
Most of the well–traveled divers all acknowledge that the best diving in the world is found in the warm waters of tropical Asia.
