The Hollis DT line of wings are another brand-new series designed for double cylinders. The DT50 features a 360 Degree tapered profile for heavier cylinders, to increase lift towards the hips, promoting better horizontal trim in dive position while still allowing perfect surface floatation. Target audience for the DT50 is focused on the dedicated dry suit diver, with heavier cylinders in cold water. Tank slots on this model, allows the occasional single tank dive without the need for a single tank adapter plate. This reduces weight and unnecessary accessories while traveling. The bladder is a two-piece design, with a rugged 1680 Cordura nylon outer shell to prevent abrasion and punctures, and a 420-denier nylon internally urethane laminated with radio frequency (RF) welded seam inner bladder to maintain the buoyancy.

It features improved ergonomics for a more comfortable fit, but is still short enough to fit smaller frame divers. The Stainless-Steel version weighs in at 6.5 lbs. (2.85 kg), it is laser cut and CNC bent, which give this awesome new appearance.

- Hollis DC7 500SE Regulator with Maxflex Hose -
Introducing the Hollis Gear DC7 Regulator, a high-performance system that combines an over-balanced diaphragm first stage with a servo-controlled second stage for exceptional airflow and precision. This regulator is designed to meet the strict CE standard for cold-water performance, and its environmentally sealed first stage ensures the delicate internal parts remain protected from contaminants like salt, sand, and chlorine.

The DC7 First Stage Regulator features a secondary diaphragm that completely seals the main spring cavity, providing excellent resistance to freezing or corrosion in icy or contaminated waters. Crafted from marine-grade brass with a black anodized finish, this DIN 300 bar (4350 psi) first stage offers four low-pressure (LP) and two high-pressure (HP) ports for optimal hose routing in both back-mount and side-mount configurations. Nitrox compatible up to 40%, this regulator requires less maintenance than models that expose internal mechanisms to contaminants.

The 500SE Second Stage utilizes a servo-controlled valve in a side exhaust configuration to deliver unparalleled performance for both air and tri-mix divers. Its innovative design ensures a gentle inhale activates the valve, providing increased airflow through multiple ports. This pneumatically balanced regulator features a large soft purge cover for easy clearing, a patented orthodontic mouthpiece for comfort, and can be configured for left or right positioning without any upside-down issues.

Designed with recreational divers and underwater photographers in mind, the side exhaust configuration keeps bubbles away from the face. Constructed from durable materials like Delrin plastics, rubber, stainless steel, and chrome-plated brass, the DC7 500SE Regulator comes standard with a 30-inch Maxflex hose for enhanced flexibility and reduced jaw fatigue. The package also includes a bolt snap tie point and an owner's manual for your convenience.
