Ramesh Singh –
I like how the mouthpiece feels and the airflow is really smooth. Only thing is, the swivel feels a bit stiff out of the box—does it get looser over time?
Imran Hanafiah –
Thank you for the feedback, Ramesh! The swivel hose may feel a little firm initially but typically loosens up with use. If you continue to experience stiffness after several dives, please contact us for further assistance.
Khalid Mohamed –
I just took the Atomic B2 Swivel Octo – Yellow 36 for its first few dives and it worked flawlessly. Super easy to locate and use, even in slightly murky water, and my jaw felt much less tired after the dive.

Vivian Chan –
Is the yellow hose UV-resistant? I want to be sure it won’t fade too quickly if I dive in sunny locations.

Hi Vivian, yes, the yellow hose on the Atomic B2 Swivel Octo is UV-resistant and designed to retain its high-visibility color even with regular exposure to sunlight. Proper care and rinsing after each dive will also help maintain its appearance.
