The AT20 is the predecessor to the XTX20. We brought it back to the Apeks line up because it represents an excellent value. This is an ideal entry-level regulator that can spoil divers in a hurry.

Features & Benefits

This high-performance regulator boasts an balanced first stage coupled with a pneumatically balanced second stage.

The smooth, quiet breath is sure to enhance your diving enjoyment.

Designed for water temps above 50°F / 10°C 

The Comfo-bite™ mouthpiece, with its patented bridge virtually eliminates jaw-fatigue

Compatible with EAN40 out of the box. 

First Stage:

  • The first stage is a balanced diaphragm type that offers consistent performance from start of dive until end of dive, regardless of depth.

  • 1 HP port and 4 MP ports are available

  • Available in yoke only

Second Stage:

  • Pneumatically-balanced second stage results in smooth, easy breathing

  • The large purge button on the AT20 is easy to operate even with thick gloves.

  • The integrated venturi control provides a performance boost at depth while preventing unwanted freeflow at the surface.

  • An extremely efficient exhaust valve improves the breathing performance of the regulator

  • The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue

  • Offers a compact, integrated exhaust tee

XL4 Octopus

The AT20 Octopus is a great match for the AT20 regulator. It provides the same features and performance as the AT20 second stage but comes with a high visibility yellow front cover and a 36” yellow hose. It is designed for water temperatures above 50º F (10º C)

Features & Benefits

  • Pneumatically-balanced second stage results in smooth, easy breathing.

  • The diver has full control of the venturi by means of a lever so as to prevent accidental freeflow when the octopus is not being used.

  • The Comfo-bite™ mouthpiece virtually eliminates jaw-fatigue.

  • It is designed for water temperatures above 50º F (10º C).

  • Compatible with EAN40 out of the box.
