The ring bungee method for managing sidemount bottles has received good acceptance and with anything people want to modify it and make it their own. I want to explain the concept behind it so you get the most from it. We call it a 12” ring bungee because from end of quick link to end of quick link is 12”. We played with various bungee thicknesses and lengths to get the best combination of stretch to attach the bottle and recoil so the bottle rest under the arm when only the buoyancy has to be dealt with.
We get requests for longer bungees. DON’T DO THIS… the stretch is
good for bottles up to the 8-inch, 120 cu ft cylinders, believe me I
have tried it on them. If you need to lengthen the overall strap because
you are thick through the chest add a quick link to
the side that attaches to your backplate or TransPac. This will move
the ring forward for access but the bungee stretch is the same for good
recoil to keep the bottle under the arm when diving.
Every quick link
will add approximately 1” of length. You may find that after doing this
you want to shorten them as you get use to attaching the bottles its
gets easier with practice. When I teach a CCR class cave divers I have
them spend at least 20 minutes following a line and doing bottle
switches. The first few passes are comical, but it finally gets so easy
they don’t even think about it. My point is don’t lengthen the bungees
permanently when a little practice will make the shorter ones more
desirable for bottle trim.




Underwater ExplorersDirDirect is a world-leading online dive shop run by Underwater Explorers based in Portland, Dorset, UK. Underwater Explorers is a dive centre with a striking difference. It was born out of the concept of "Hogarthian" diving, safe and streamlined equipment configuration, using the most robust products available for recreational and technical diving -- but at the same time, keeping it simple. It is based on the concept of "less is more" in diving and acts as an equipment outlet, training facility and source of sound advice.
