Exploring an indoor environment, such as a cavern or large wreck, is an exciting activity. However, getting traditional diving equipment through the confined spaces of these areas can be a challenge. By improving hydrodynamics with a sidemount configuration, adventurous divers can explore the tightest of spaces. The Extended Range Sidemount program teaches you how to use the sidemount configuration, as well as techniques for using the various stage cylinders effectively during decompression diving with this type of configuration. Upon completion of this program, you will earn SSI's Extended Range Sidemount certification, which will allow you to apply the Sidemount configuration to all other Extended Range programs.
