SCUBAPRO S360 Octopus

If you're going to dive with a safe second (and you definitely should) the last thing you want to do is scrimp on your backup breather. On the contrary, you want to choose a safe second stage that's every bit as good as a primary second stage. In SCUBAPRO-speak, that's called the S360 OCTO.

The lightweight technopolymer S360 is an easy-breathing air balanced second stage used on a number of quality SCUBAPRO reg systems. It comes with pre-tuned inhalation for simplicity, and includes a Venturi-Initiated Vacuum Assist (VIVA) switch for easy detuning to avoid free flows. This makes for a sweet-breathing primary second stage, and it's also the ideal set-up for use as a backup breather.

The S360 OCTO takes the standard S360 second stage and adds a high visibility yellow cover so it's easy to see, and a 39-inch yellow hose that makes it easy to share with a buddy in need. With the balanced airflow you get consistent air delivery regardless of depth, adding a level of security and confidence when you need it the most.

When you need a safe second you want the best -- that's the S360 OCTO.
