Description

The high performance MK25/S600 reg system is known for its low work of breathing and tremendous reserve capacity. Year after year, in successive independent tests, it has consistently ranked as one of the top-performing regs on the market.

First Stage MK25 Evo:

• Air-balanced flow-through piston design provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• Patent-pending XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the current MK25 without compromising breathing performance.
• New spring insulating coating, body insulating bushing (non-metal cylindrical interface separating metal parts from water), anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance. (Key insulation system components are visible in blue.)
• Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
• Two high pressure and five high-flow low pressure ports on a swivel turret maximize hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• 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 (l/min/SCFM): >8500/301.
• Intermediate pressure (psi/bar): 130-142/9-9.8.Second Stage S600:
• Full metal valve housing is able to withstand years of aggressive diving.
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
• Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
• Weight: 6.8oz/193g.
• Airflow at 2900psi: 1850 l/min – 66 SCFM.
• Maximum low pressure: 203psi/14bar.
