Apeks once again takes the lead in the game as we enter 2020, with an upgraded version of their range-topper MTX-R high performance regulator. The new MTX-RC adds a Venturi lever and a cracking resistance control to the MTX-R, allowing divers to fine tune the performance of the regulator to conditions they are diving in.

Let’s not forget, fine tuning doesn’t just mean tuning up of a regulator already tuned to perfection for extreme cold water diving, but also tuning down when such performance isn’t required.

Just like its sibling the “R”, this regulator performs fabulously and looks great with its grey and satin finish colour scheme with or without an ‘octopus’. More over the regulator second and first stage are nitrox compatible up to 40%.

Users can purchase the MTX-RC as a recrational set consisting of 1st and 2nd stage as well as yellow octopus or purchase the MTX-RC 1st Stage and/or MTX-RC 2nd Stage separately to use with any single or double tank setup. Checkout our Apeks MTX-RC regulator sets online.


“In use, the MTX-RC provides a sublime breathe. With the cracking resistance dialled fully open and the venturi set to ?dive?, inhalation is effortless and silky smooth, regardless of orientation, but in situations where you need to temper this performance ? in extreme cold water, for instance, or if you were using a powerful scooter, you can increase the cracking resistance, which in its highest setting is more akin to the original MTX-R.”
