Scubapro Hydros X Men's BCD Package w/Balanced Inflator and MK25/D420 Regulator

The Hydros X is the world's 1'st front-adjustable BCD to offer fully injection molded Monprene thermoplastic harness. This feature allows you to tailor the harness shape to perfectly fit your torso & creating superior comfort. Add the full-sized backpack & stainless-steel Super Cinch tank band & you also get excellent stability both on the surface & at depth. The air cell & harness are modular & detachable. The bladder, made out of EndurTex high-tenacity 420 nylon fabric, is extremely lightweight & durable while offering generous lift capacity, aided by lower back bellows. In the event of damage, every component on the Hydros X is detachable & easily replaceable.

Its flat-buckled quick-release integrated weight system & rear trim weight pockets work together to offer a more comfortable & balanced ride when cruising the depths. The big zippered cargo pockets offer great gear-carrying capacity & 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 w/multiple D-Rings & mounting points that easily attach various dive accessories.

Monprene thermoplastic harness is extremely resistant to UV, chemicals & 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. Weight integrated w/releasable weight capacity of 24lb (11kg) & 8 lbs. (3.6 kg) non-releasable capacity. The BCD's lift is 29.2 to 44.9lbs (13.25 to 20.4kg) depending on BC size. Buoyancy is controlled w/Scubapro Balanced Inflator mechanism, right shoulder & left bottom overpressure relief/dump valves w/pull cords. The Balanced Power Inflator provides high inflation speed, especially at depth. Inflator is equipped w/rapid pull dump mechanism w/cable pull for easy deflation. Inflator includes a 3/8" threaded low-pressure hose. BCD comes w/an owner's manual.

Scubapro engineers created a 21st century regulator in terms of quality, reliability, performance & style. The D420 has a balanced valve inside a housing supported by a full metal structure. This Progressive Flow Control Valve, is able to deliver abundant airflow for the best breathing performance, w/a natural smoothness like breathing on the surface. The uniquely shaped fiberglass-reinforced nylon casing is ultra-durable & allows LP hose to be connected on the right or left side for maximum rigging flexibility. A dive/pre-dive system switch on the top of the casing w/thumb tab is for adjusting the direction of airflow right out of the valve. The efficient purge button is a technical jewel based on a concept that gives the D420 its unique face. Teamed w/the MK25 EVO balanced piston 1'st stage, this is a regulator system purpose-designed for today's avid divers.

The MK25EVO is a balanced piston 1'st stage. It is a superior regulator thanks to its stable intermediate pressure resulting in a constantly high delivery of air. This means instant airflow at any tank pressure & water temperature for a real carefree dive. Air balanced, flow-thru-piston 1'st stages deliver significantly more air to the 2'nd stage than any other 1'st stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter & more sensitive components, resulting in ultra-fast breathing response, instant delivery of air on demand, & extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. A balanced piston performs equally in warm and cold-water environments.

The MK25 EVO has two 7/16" threaded high-pressure ports (HP). The arrangement of high & low-pressure hoses is crucial to diving comfort. 2 HP ports allow for individual positioning of the 1'st stage (pointing up or down). This allows the diver to position gauges on the right or left side & increases freedom of movement for head & neck. Multiple low-pressure ports (LP) - Ultimate freedom in arrangement of LP hoses, the MK25 EVO accommodates 5 HF (High Flow) 3/8" threaded ports on a swiveling turret, which allows for 360° swivel of hoses. HF ports deliver about 15% more air than conventional ports.

Cold Water Diving can be drastically different, including extreme cold water & outside temperatures, posing possibility of regulator freezing. The MK25 EVO uses Scubapro's Extended Thermal Insulating System (XTIS). The Scubapro MK25 EVO 1'st stage regulator meets EN250-2014 requirements for cold water diving, CE approved for 3360psi (230 bars). This model goes beyond this qualification & has been tested in extreme cold conditions at less than 36°F (2.2°C). The MK25 EVO has a thermal insulating coating on key internal components & an encapsulating main spring bushing that resist cooling effect in previous MK25 1'st stage regulators, also as a specific anti-freezing measure; Scubapro engineers designed a finned cap for the MK25 EVO 1'st stages for optimal-cold water diving. The fins of the XTIS act as a radiator to increase the surface area of heat transfer from the water to warm up internal parts that have been cooled by the gas pressure drop. The MK25 EVO's bigger body cap, body w/insulating bushing & ribs, antifreeze cap patented isolation system w/all internal parts fully insulated to improve cold water performance.

System gives the diver superior cold-water performance, equal to that of Scubapro's MK17-1'st stage. Now you have the option of a high-performance flow-thru piston design, w/a high level of performance in cold water. The MK25 is made from marine grade chrome plated brass & has a balanced composite/stainless steel piston. The D420 2'nd stage carries on the D-Series heritage w/the latest advances in breathing performance technology. Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow w/a natural smoothness comparable to breathing on the surface. 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 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. Large purge button is easy to reach & depress, w/or w/o gloves. Exhaust tee is compact & efficiently deflects bubbles from the diver's view while enhancing ease of exhalation. Super-flow 3/8" threaded 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. Regulator weighs 40.8oz (1,157g), is Nitrox compatible up to 40% oxygen & comes w/an owner's manual.
