The Apeks AT Octopus is a more affordable way to get high performance out of an Octopus. It provides the same features and performance as the XTX20 second stage and includes left/right-hand reversibility. It comes with a high visibility yellow front cover and a 36" (91.44cm) yellow hose. It is designed for water temperatures above 50 Degrees F (10 Degrees C). The AT purge buttons are large and easy to operate. A 2-stage progressive purge is used. Press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags, etc., then press in the center for the full effect of the purge, i.e., when regulator clearing, etc. Can be converted from a right-handed hose configuration to a left-handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must only be performed by an Apeks Authorized Service Technician. Braided flexi-hoses are now standard on all models. These hoses are lighter weight, more flexible, and more durable. Compatible with EAN40 out of the box. The pneumatically balanced second stage results in smooth, easy breathing. Manufactured with active protection against infection as all molded parts are produced with an additive that kills MRSA, protects against E. coli, bacteria, and fungi, and is also very effective against viruses, mold, yeast, and algae. A silicone exhaust valve improves the breathing performance of the regulator. The Comfo-bite mouthpiece virtually eliminates jaw fatigue.
