Scubapro's cold water 1st stage has now been upgraded to the new MK17 Evo! The environmentally sealed diaphragm regulator is air balanced and delivers under all circumstances in all climates!

As the first stage is environmentally sealed, no sand, salt or silt can enter your first stage, so no unwanted free flows!  In fact it is so good that it is our Servicing Technicians favorite and he has serviced thousands of regs in the past 40 years.

The MK17 Evo has increased air flow on all LP ports and an incredible air flow of 6900L per minute (at 200 bar).

The MK17 is also very versatile with 4 LP (2 High-Flow-Port) and Dual HP Ports.

We've been using the MK17 in our school regs for some time so can highly rate this first stage.
