Regardless of which type of alternate air source you select, remember that its performance will depend on the ability of the regulator first stage to deliver air, particularly when it is supplying two second stages and a power inflator. The bottom lines: Given the type of diving you plan to do, how will it work for you in a worst-case scenario? How much risk are you willing to accept? If you dive solo, under demanding conditions or in overhead environments, the greater your need for a completely independent air source and a high-performance regulator as your alternate air source.

Atomic SS1 Octo Customer reviews

Scuba Lab Testers Choice!

 

And the reviews are in:
"No doubt about it. Atomic has raised the bar with the SS1, creating the first safe second that really could be compared to a high-performance primary. And the best news - it will fit on most any brand of BC, thanks to a unique adapter device." - Sport Diver magazine

"The SS1 breathes better than many primary use regulators and generated the best overall simulator performance among the integrated inflator/regs...and earned the highest ergonomic scores of all the units we tested" - Scubalab
