While many dive Octo’s are feature-lite shadows of the real deal, Apeks know that if you ever need your Octopus in the extreme technical environments their MTX-R regulators are designed to handle your gear can’t be compromised.

The MTX-R Octopus features the same unparalleled specifications as the MTX-R 2nd stage allowing it to function flawlessly in brutally cold, or deep water.

It’s pneumatically balanced design allows you to enjoy consistent and effortless breathing even when your air reserves are at minimum. Based on the Military Apex MTX regulator, the MTX-R Octopus has been tested to NEDU (Navy Experimental Dive Unit) Standards. It can handle near zero degree temperatures down to 60m, easily.


With bright yellow highlights on the tough, reinforced body, it’s easily visible. The long braided hose is also clear yellow, so you can always see it, even in murky water.


As with all Apex Octo’s the MTX-R Octopus features a comfo-bite mouthpiece. These mouthpieces feature a bridge that sits across your plate. This prevents the dry, cool air from your regulator drying out your palate while also providing support for you Octopus reducing jaw fatigue.
