Wei Ming Tan –
I really like how compact the Sherwood Gemini Octopus is compared to my previous setup. It makes my BCD a lot less bulky and feels easier to move around underwater. The mouthpiece is comfortable enough, but I still get a bit of jaw fatigue after really long dives.

Does the Gemini Octopus fit all BCD inflator hoses, or do I need a special adapter to install it?

Used the Gemini on three dives so far and it worked flawlessly, even when my buddy needed to use it as an alternate. The bright color really helps make it visible in low light. Happy with the performance and reliability.
