Extended Range Sidemount

A-1 Extended Range Sidemount Diver Program


Why take this course?

Extended Range Sidemount

Extended Range Sidemount diving offers many advantages over the use of traditional back mounted cylinders. In the past, options for increasing gas supply available for a dive involved manifolding two cylinders together, which doubled the weight a diver had to carry on their back.

With extended range sidemount diving, the cylinders move from your back to your side. Transportation of cylinders topside is then much easier. Cylinders may be donned after entering the water, eliminating problems with wearing heavy cylinders out of the water. Redundant gas supply increases bottom time, and adds an extra level of safety to the dive. Sidemount diving provides added stability with the cylinders on the side of the body and double the gas supply. It is an alternative way to streamline in the water, easier to “trim out”, and the diver has the ability to monitor all their equipment because it’s right in front of you.

Use of a single sidemounted cylinder is also an option, which offers all of the advantages of easier transportation of cylinders, the ability to enter the water without having to carry a heavy cylinder, and equipment monitoring. Or, a diver could use two smaller cylinders for the advantages of increased bottom time, redundant gas supplies, and added trim and stability.
With a properly rigged sidemount system, your center of gravity is changed, and your cylinders almost feel like they are not even there!

If you’ve looked into technical diving, you realize that tec divers always wear more than one tank. Sidemount is an increasingly popular way to configure multiple cylinders for technical diving. You can enter the world of tec diving with the XR Sidemount Diver course and apply what you learn to other XR courses.
