Questions and Answers for ScubaPro MK17 / A700 Regulator System:

  • George:

    Sirs: For many years I dove with a "piston-style" regulator, which was great for several reasons, including the fact that it breathed the same in any position. As a result, I mounted it at an offset angle, and it worked just fine. However, I recently purchased this ScubaPro MK17 / A700 Regulator combination from Love it. But I am wondering - as a "diaphram-based" regulator, can I mount the first stage with the main lobe (where the "fins" and black cap are located) in the "down" position, or does a diaphram regulator need to be mounted on the tank with the "lobe" positioned in the "up" position to obtain maximum performance. I just used this unit in Palau, and loved it. However, I did bang the back of my head against the lobe when craning my neck to see mantas playing in the water above us. I am thinking if I mount it "lobe down," I may be able to minimize this problem. Any comments from you guys out there (and thanks in advance for any feedback!) Ged Smith

    As far as the average diver/user is concerned there is no difference in the operation between a piston and diaphragm 1st stage. They both do the same thing in the same way for you.

Cold water divers or those frequenting harsh environments will appreciate this perfectly matched pair. The A700 is a complete complement to the MK17, a high performing balanced diaphragm first stage engineered exactly for such conditions.
Balanced technology provides consistent performance at all tank pressures, at any depth and optimizes the second stage performance.
Dry ambient pressure chamber provides better protection and performance in cold water, prevents water entry, enhancing trouble-free operation.
Balanced diaphragm design, with ultra-fast flow to the second stage to obtain the lowest possible work of breathing at depth.
Available in either 232bar INT or 300bar DIN configurations
Compact dimensions for light weight comfort.
Diver adjustable inhalation effort with micrometric adjustment knob enables personalised breathing effort control.
Newly aligned VIVA system for more precise control and comfort.
Super high flow exhaust valve allows air to exit more freely and lowers the exhalation effort; also keeps bubbles away from face and mask.
