Questions and Answers for ScubaPro MK17 / G260 Regulator System:

  • howard:

    Why would you choose a MK 17 over the MK 21? Same price it appears that both have pretty much the "same stuff". Thanks.

    Bob  (Certified Scuba Instructor at

    The MK17 was designed as a sealed system mainly for colder conditions and ice diving.

  • howard:

    Regarding the ScubaPro MK17 w/G260. What do you consider cold water? Monterey Bay usually has a surface temp of 52-54 year round with cold thermoclines as you go deeper. As an older diver I plan on a few dives locally but a lot more in tropical areas such as Cozumel and Lighthouse Reef in Belize. So my upgrade from XS Scuba SeaAir might be the MK17 or the MK21 for both myself and my wife.

    Bob  (Certified Scuba Instructor at

    Monterey Bay is considered temperate water. Cold water is considered waster temps in the mid to high 40''''s and lower. Basically ice diving.

G250 Second Stage
G250V has improved the breathing performance by 50%. Working inhalation & exhalation are easier and stress free. Comparing the G250HP which required 1,29 Joules/Ltr with the new G250V requiring 0,68 J/Ltr means you spend less energy to breathe the same volume of air.

·G250V is a full metal system- composed of a full metal inlet tube, metal orifice, metal knob plus a metal hose connector/heat exchanger. Serious construction for serious divers plus high cold-water resistance.

·New self contained cover concept- reminiscent of the classic G250, but much stronger for years of trouble-free diving. Also easily dismountable even underwater, thanks to the new no-locking pin system. Keeps you in control, no matter what type of diving you enjoy.

·New VIVA knob - for easy Venturi Adjustment, even with thick gloves.
