MK25 EVO First Stage:

• Air balanced flow-through piston in chrome-plated brass body.
• Patented Extended Thermal Insulating System fully isolates the mechanical elements from the cold.
• spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread improve cold-water performance.
• Anti-freeze protection increases breathing reliability when diving in extreme temperatures.
• Two opposing high pressure ports allow first stage to be positioned up or down.
• Five high-flow low pressure ports maximize hose routing options.
• External intermediate pressure adjustment enables fine-tune performance.
• Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
• Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/572.
• Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
• Intermediate pressure (psi/bar): 133-142/9.2-9.8.

A700 Second Stage:

• Rugged, durable full metal case and valve housing (barrel).
• Larger diaphragm inside a compact casing increases breathing sensitivity.
• Air-balanced valve smoothes inhalation effort at varying depths and supply pressures.
• User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
• Super-flow hose features oversized bore, allowing more air to flow.
• Ultra-comfortable orthodontic mouthpiece is easy to grip.
• Weight (without mouthpiece): 9.2oz/261g.
• Airflow at 2900psi: 2000 l/min – 71 SCFM.

Scubapro R195 Octopus:

• High vis yellow cover
• Includes 1m yellow hose
• Reversible hose attachment for easier routing
• An adjustable VIVA control redirects air flow to reduce chance of free flow
