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.
