AT20, a fully balanced regulator at an entry level price.  This regulator really is such great value.

1 x 1st stage 2 x 2nd stages (Primary and Octi)

This high-performance regulator boasts a balanced first stage coupled with a pneumatically balanced second stage.  A balanced first stage and second stage makes for much easier breathing.  In an unbalanced regulator as your tank empties or you go deeper the air becomes harder to breathe.  You really have to 'suck' the air out of the tank.  With a balanced regulator, it doesn't matter how deep you are diving or how empty your tank is you will have the same easy breathing experience.  

With this set up you get 1 High Pressure Port (for your SPG or transmitter) and 4 Low Pressure Ports (for your Octis, BCD Inflator hose, Drysuit hose for example).  

The second stage also has a Venturi Lever which enables you to switch the regulator into a 'pre-dive' and 'dive' mode.  This makes it less likely to free-flow on the surface (pre-dive) and easier to breath underwater (dive mode).

The regulator also boasts smooth quiet breathing and is designed for water temps above 50°F / 10°C (this is known as a warm water regulator ... if you can class 10°C as warm ... brrrr)

When you order simply choose between YOKE (screw on over the tank valve) or DIN (screw into the tank valve) configurations.  We have also included an option to upgrade to add an SPG onto the regulator set.

The Comfo-bite™ mouthpiece, with its patented bridge virtually eliminates jaw-fatigue while Scuba Diving.

Compatible with EAN40 out of the box.

Comes with full manufacturer's warranty and free shipping anywhere in New Zealand.  As we back all of our products, if you are not satisfied, for ANY reason, then simply return the regulator for a full refund.

We'll assemble and test the regulator onsite so it's ready for you to use straight out of the box.
