Product Description


BTS SO40 Aluminium Cylinder, includes tank valve

BTS 5.7 Litre / 40 cuft cylinders
make the perfect decompression bottle. The longer slender shape allows the bottle to cut through water with ease, a BTS ali 40 is hardly noticeable during a dive. Typically a 40 cuft cylinder will be used for pure oxygen as this is a shallow stop, with a typical 180 bar fill the cylinder is barely negative and is perfectly neutral around 130 bar. This size cylinder can also be used for 50% with decompression stops totalling around 20 minutes. A BTS 40cuft cylinder is a good choice for a decompression bottle in the 25-40 meter range. BTS 5.7 litre cylinders are available in either white or silver, we think silver is the best option as white cylinders can start to look tatty when being dived hard. 

Peter Steinhoff produced an article on how to correctly rig a cylinder for stage or decompression purposes, it can be found here.
