Aeris' 400 Pro DVT regulator's patented dry valve design means you won't have to sacrifice performance and durability in order to have a regulator that won't flood. This pneumatically-balanced second stage will be the work horse of your dive gear; it will keep you breathing easily dive after dive. The diver-adjustable breathing valve allows you to control the airflow to match your breathing rate and body's air needs.

The 400 Pro DVT's lightweight design and patented orthodontic mouthpiece mean you'll be comfortable and breathing easily throughout your dive and won't face post-dive jaw discomfort once you've returned to the surface.
