ScubaPro MK17/G260 Tatical Balanced Regulator

Premium environmentally sealed system gets serious.

The go-to reg for tech divers and cave explorers now features a super-technical second stage upgrade. The MK17/G260 is a serious reg system purpose-built for diving deep, diving cold, diving on silty bottoms and in hazardous water conditions. If you need to get more serious than that, you might have to go tactical, as in the MK17/G260 TACTICAL.

With the G260 TACTICAL SCUBAPRO engineers have taken the most imitated air balanced second stage design of all time and offered it with a rugged, nylon fiberglass casing fitted with a dark anodized aluminum ring. Then they added a stealthy design to the inhalation effort control knob, and topped it off with a new hose swivel that increases range of motion, decreases jaw fatigue and enhances overall comfort and control. The G260 TACTICAL is built with metal components (inlet tube, orifice, inhalation control knob and hose connector) to ensure excellent cold-water performance. It also offers a left-right hose attachment option, making it a great choice for tech diving configurations.

Teamed with the G260 TACTICAL is the MK17, a high performance, balanced diaphragm first stage engineered specifically for cold water and harsh environments. Completely sealed off from the elements, neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the inner mechanism. This total sealing system also allows for a dry ambient pressure chamber which works to prevent freezing, so you can be assured of trouble-free operation even in the coldest conditions. The MK17 delivers fast and reliable airflow with every breath, plus it's user-friendly, offering two high pressure and four low pressure ports, two of which are high-flow (high-flow ports deliver about 15 percent more air than conventional LP ports).

The MK17/G260 TACTICAL is a serious breathing system that's as tough as it looks. Built for demanding divers and demanding dive conditions, it is ideally suited to technical diving as well as cave diving, where it's critical that every breath taken results in top-of-the-line performance.


  • Air balanced diaphragm design delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Environmentally sealed system prevents water and pollutants from fouling the inner mechanism.
  • Dry ambient pressure chamber increases freezing resistance, ensuring trouble-free operation in the coldest conditions.
  • Two high pressure, two low pressure and two high-flow ports maximize air delivery and hose routing options.
  • External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily without the need for disassembly.
  • Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
  • Weight: INT 232 - 30oz/850g; /DIN 300 - 22oz/625g.
  • Airflow at 2900psi: 6500 l/min - 230 SCFM.
  • Intermediate pressure (psi/bar): 130-142/9.0-9.8.


  • Casing is built from rugged nylon fiberglass and fitted with a dark anodized aluminum ring to stand up to aggressive diving.
  • New second stage hose swivel with flexible cover enhances range of motion, comfort and control.
  • Metal components provide increased resistance to freezing when diving in extreme water conditions.
  • Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
  • High-flow exhaust valve reduces exhalation for better overall breathing comfort.
  • A stealth-designed diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes.
  • Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
  • Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
  • 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
