• Dry Ambient Pressure Chamber
  Increases freeze resistance and ensures consistent performance in icy environments.

• Air-Balanced for Smooth Delivery
  Maintains steady airflow at all depths and tank pressures, thanks to the air-balanced diaphragm system.

• Improved Port Layout
  Two HP and four high-flow LP ports enhance scuba hose routing flexibility and airflow to second stages and accessories.

• External Intermediate Pressure Adjustment
  Allows technicians to fine-tune performance without disassembly.

• DIN and Yoke Options Available
  Choose between 3364 psi / 232 bar Yoke or DIN 300 bar fittings to match your tank and diving style.

Detailed Description

The Scubapro MK17 EVO is a compact and robust 1st stage regulator designed to perform flawlessly in environments where other systems can fail. Built around a balanced diaphragm design, it delivers a stable supply of air regardless of depth or remaining tank pressure. This makes it a trusted choice for divers who operate in extreme conditions - cold lakes, silt-heavy caves, or contaminated water.

Unlike unsealed designs that allow water to contact internal components, the MK17 EVO features a fully dry ambient pressure chamber that isolates the mechanism and prevents freezing or corrosion. The result is dependable operation in temperatures that push other regulators to their limits.

With its redesigned body, the MK17 EVO is more compact than the original MK17, yet offers improved breathing performance and a smarter port configuration. Two high-pressure ports and four high-flow low-pressure ports provide optimal hose routing for any configuration - backmount, sidemount, or stage bottle setups.

Whether you're looking to pair it with Scubapro’s premium second stages or build a dedicated cold water setup, this dive regulator stands out as a versatile, durable, and field-proven solution.
