Questions and Answers for Apeks AT20 Regulator:

  • adam:

    I was wondering how many high pressure attachment points are on the first stage. Will this regulator have an attachment point for both an spg gauge and a transmitter?

    Bill  (Certified Scuba Instructor at Scuba.com):

    2 HP ports.

  • Jonny:

    is the AT20 usable for tech and side mount diving?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Jonny, yes you can use this as a tech regulator or as a side mount regulator.

Regulator - the 'heart' of your diving equipment and the most important choice when assembling your diving system. As regulator specialists we are dedicated to designing and manufacturing breathing equipment that gives reliable high performance in the most demanding situations - perfect for professional and 'tech' divers and the only choice for serious recreational divers. The performance of your regulator is of the utmost importance as this reflects the ease of breathing in all diving conditions and increases the enjoyment and safety of your dive. Our equipment has evolved through many years of research and development. Independent tests prove their superiority, comfortably exceeding the tough US Navy group A test and the CEN European Standard CE (the first regulators to achieve this mark of distinction).

While our performance figures are impressive, even more important are the comments we receive from our customers. Divers choose our regulators because their friends, family, colleagues, and instructors, have wholeheartedly recommended Apeks. The most experienced divers from all disciplines have put their faith in our equipment. John Bennett - the first man ever to dive to a depth of over 300 meters or 1,000 feet used Apeks for his record breaking dives. As John said at the time, 'Apeks regulators breathe superbly. They're simply the best'. We have achieved our original goal - to make the best diving equipment in the world - and we will continue to strive for excellence.

The AT20 regulator is no longer available with the Unsealed Swivel Turret (UST) 1st stage. This is now supplied with the US4 1st stage. The AT20/US4 regulator has been designed for warm water diving. Just because it is warm water equipment does not mean it is of low quality. The AT20/US4 is a very good breathing regulator featuring our venturi control and it is also balanced.

The first stage has 4 medium pressure ports but now without the swivel turret which is shown in the UST picture across. The medium pressure ports on the US4 first stage are on the body of the 1st stage itself. It now has only one high pressure port as opposed to two on the UST version. This regulator has been finished with as much care and attention to detail as any of our regulators, but is most suitable for warm water resort diving. A good quality, warm water regulator at a very good price.
If you require our improved version of the AT20 regulator which featured the UST 1st stage then please see the XTX20 regulator.
