The AT20 is the predecessor of the XTX20.  We brough it back to the Apeks line-up because it preresents an excellent value.  this is an ideal entry-level regulator that can spoil sport divers in a hurry.

The first stage is a balanced diaphragm design.

The first stage has one high pressure port and four medium pressure ports

The 2nd stage uses a pneumatically balanced valve system for excellent breathing

It is designed for water temperatures above 50°F (10°C)

The AT20 has an ergonomically designed control for the venturi that enables you to
control the airflow within the second stage at the turn of a lever

Comes standard with the Comfo-bite mouthpiece for increased comfort

Compatible to EAN 40, new, out of the box
