Product Overview

The Hydros X is the world's first front-adjustable BCD to offer a fully injection molded Monprene thermoplastic harness. This unique feature allows you to tailor the harness shape to perfectly fit your torso and creating superior comfort. Add the full-sized backpack and stainless-steel Super Cinch tank band and you also get excellent stability both on the surface and at depth. The air cell and harness are modular and detachable. The bladder, made out of EndurTex high-tenacity nylon fabric, is extremely lightweight and durable while offering generous lift capacity, aided by lower back bellows. In the event of damage, every component on the Hydros X is detachable and easily replaceable.

Its flat-buckled quick-release integrated weight system and rear trim weight pockets work together to offer a more comfortable and balanced ride when cruising the depths. The two big zippered cargo pockets offer great gear-carrying capacity and are easily accessible even when the weight pouches are fully loaded. Two stainless-steel D-rings provide clip-on points for additional gear. In addition, the Hydros X features a Multi-Mount Accessory Matrix with multiple D-Rings and mounting points that easily attach various dive accessories.

Hydros X is based on the same modular Monprene harness and backpack design popularized by the Hydros Pro back-inflation BCD. EndurTex high-tenacity 420 nylon fabric bladder is lightweight yet extremely durable. Monprene thermoplastic harness is extremely resistant to UV, chemicals and abrasion, plus it doesn't absorb water to minimize drying time. Rotating squeeze-style quick-release shoulder buckles allow you to route your shoulder straps to optimize fit. Super Cinch tank buckle system locks the tank in solid for maximum stability at depth. Integrated front weight system is based on the same Monprene pockets found on the Hydros Pro. Weight integrated with a releasable weight capacity of 24 lbs. (11 kg) and 8 lbs. (3.6 kg) non-releasable capacity. The BCD's buoyant lift ranges is from 29.2 lbs. to 44.9 lbs. (13.25 kg to 20.4 kg) depending on the BC size.

Buoyancy control is facilitated with the Scubapro Balanced Inflator mechanism, right shoulder and left bottom overpressure relief/dump valves with pull cords. Scubapro's Balanced Power Inflator provides a high inflation speed, especially at depth. Inflator has different shaped inflation and purge buttons for easy use even in extremely low light or murky water conditions. Inflator is also equipped with a rapid pull dump mechanism with cable pull for easy deflation of the air bladder. Included with the inflator is a 3/8" threaded low-pressure hose for attachment to the first stage regulator. BCD comes with an owner's manual.

Combining the iconic design of the original D-Series regulators with the latest advances in breathing performance technology, Scubapro engineers have created a 21st century regulator in terms of quality, reliability, performance and style. The new D420 features a brand-new balanced valve inside a housing supported by a full metal structure. Called the Progressive Flow Control Valve, it is able to deliver abundant airflow for the best breathing performance, with a natural smoothness comparable to what you might experience breathing on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable and allows the LP hose to be connected on either the right or left side for maximum rigging flexibility. A new dive/pre-dive system includes a switch on the top of the casing with a thumb tab for adjusting the direction of airflow right out of the valve. The highly efficient purge button is a technical jewel based on a new concept that gives the D420 its unique face. Teamed with the new MK19 EVO balanced diaphragm first stage, this is a regulator system purpose-designed for today's avid divers and Scubapro brand enthusiasts everywhere.

Scubapro is pleased to introduce the all new MK19 EVO 1st stage. This regulator has been fully developed by Italy R&D based on the growing technical market needs. Designed to be the ultimate first stage for cold water or contaminated diving conditions. New design makes it substantially smaller and lighter than the original MK19 and then competitors. Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate. Higher performance than competitors in terms of airflow and max depth. Swivel and dry chamber together are a premium package that fits the tech diver needs. Environmentally sealed system prevents water and pollutants from fouling the inner mechanism. New dry chamber is equipped with a double spring, making it more compact and reliable. Swivel turret comes with four high-flow LP ports plus one axial super high-flow LP port to maximize hose routing options. All low-pressure ports are 3/8" threaded. Regulator has two opposing 7/16" threaded high-pressure ports. Compact size, light weight and superb breathing performance continue in the best Scubapro regulator tradition. Ideal for recreational, technical, professional and military divers.

The Scubapro D420 second stage regulators uniquely shaped fiberglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology. Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface. Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve. Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort. Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier. Reversible hose attachment allows for either left-or-right-side LP hose connections for maximum rigging flexibility. Large purge button is easy to reach and depress, with or without gloves. Exhaust tee is compact and efficiently deflects bubbles from the diver's view while enhancing ease of exhalation. Super-flow 3/8" threaded 29.5" (75cm) hose features an oversized bore that allows more air to flow on each inhalation. Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest. The regulator weights approximately 38.8 oz. (1,100 g) without hose or mouthpiece and comes with an owner's manual.
