Built to deliver a solid flow of air in tough diving conditions, the Scubapro MK17 EVO and A700 are a success, they keep on working. The MK17 EVO 1st stage is designed to be completely sealed from the environment around it ensuring a problem free supply of air at all times and regardless of the conditions. It is more compact but delivers better flow than its predecessor. The improved internal design allows more air through the LP ports which have also been moved to allow better tubing configuration. The A700 2nd stage offers extraordinary air flow and performance which means you can pull weather without difficulty no matter what. A piece of handmade precision equipment in a full metal package.
Specifications
