Go warm, go cold, go deep, go anywhere. Enjoy control in the extreme with the MTX-RC scuba diving regulator. Combining rugged, military grade engineering with the super-smooth breathing experience that Apeks regulators are renowned for, the MTX-RC is the regulator that lets you explore more.   Featuring the same freeze-resistant technology enjoyed by the whole MTX-R range, the MTX-RC resists free-flows in even the coldest temperatures, while offering the user the additional flexibility to adjust the settings for a more comfortable breathe in less extreme environments. All this is achieved using an innovative first stage design that protects the regulator from freezing and a full set of user controls on the second stage to adjust the breathing performance based on the divers individual needs. Includes a tactical style messenger bag to keep your regulators safe on your travels. Perfectly sized for a laptop, its also your new work bag! What's in the box: 1st stage, 2nd stage, Octo and 2
