Where to buy

The world-renowned Catalina cylinders is a homegrown company, their tanks manufactured in California. They supply scuba divers around the world, in over 100 countries! If you find the regular S80 too big/heavy or perhaps it’s too long on your back, then choose S63. 

Approximately 4 inches shorter and 4lbs lighter, many smaller divers find downsizing makes for a much comfier dive. But don’t worry, downsizing doesn’t mean downgrading! Buying a Catalina cylinder means you will be buying a world-class product.

Things we like:

  • Great tank for smaller divers or children/teenagers
  • Shorter and lighter
  • Can be used with both DIN & Yoke regulators
  • Easily refillable
  • Reputable Brand

Things we don't like:

  • Smaller tank so not as versatile
