Sidemount is by far the best configuration to use for developing every divers essential skill set. This video highlights what is covered with the side mount essentials training. There is a PADI and PADI TecRec option for divers wanting certification and a non-certification option for experienced divers. These dives were made using the Steve Bogaerts designed razor side mount harness. The "modular bcd" or buoyancy device being used in this video, is a specialist "cave diving" piece of equipment, requiring specialist training. Sidemount buoyancy devices for "Open Water" diving environment may require more lift capacity - filmed in Mexico by Jason from www.scubavideoservices.com, edited by Steve from www.sidemountscubadiving.com
