Ultimate Scuba Regulator for Cold‑Water Dives

MK19 EVO BT/G260 Regulator System

The MK19 EVO BT/G260 marries the best of SCUBAPRO’s MK17 and MK25 lines, offering a lightweight, high‑performance regulator that excels in cold and contaminated water.

First Stage

Featuring an environmentally sealed diaphragm and a swiveling low‑pressure turret, the first stage’s double‑spring design delivers a compact yet responsive feel. Two high‑pressure ports and four low‑pressure ports around the turret give divers flexible hose routing, while an axial super‑high‑flow port maximizes breathing efficiency.

Second Stage

The G260 second stage is built for professional use. Its pneumatically balanced valve and metal valve barrel, coupled with a heat exchanger, ensure smooth breathing even in frigid water. A large air‑balanced diaphragm delivers consistent airflow across depths and tank pressures, while a self‑adjustable breathing knob allows fine‑tuning of air paths. SCUBAPRO’s Black Tech DLC coating protects both stages from corrosion and wear, and the system’s environmental seal keeps contaminants out.

Technical Features Summary

• Air‑balanced flow‑through piston in a Black Tech‑coated brass body.
• Air‑balanced second‑stage valve levels inhalation effort at varying depths and pressures.
• Venturi‑Initiated Vacuum Assist (VIVA) pre‑dive switch blocks free flows in cold or contaminated water.
• External pressure adjustment enables quick performance tweaks.
• Patented XTIS (Extended Thermal Insulating System) protects internal components, reduces ice build‑up, and extends cold‑water endurance.
• Anti‑freeze protection with metal components (valve inlet tube, air barrel) enhances reliability in freezing conditions.
• Axial super‑high‑flow low‑pressure port and four high‑flow ports offer optimal hose routing for technical configurations.
• Super‑flow hose delivers extra air per breath.
• High‑flow exhaust valve reduces exhalation, improving overall comfort.
• Dual high‑pressure ports allow first‑stage placement either up or down.
• Large diaphragm and nylon‑fiberglass casing provide responsive breathing at all depths.
• Comfort‑oriented orthodontic mouthpiece ensures a secure grip without compromising airflow.
• BlackTech coating includes FDA‑approved nickel and a durable Diamond‑Like Carbon surface.

Carbon‑Fiber Advantage

Carbon fiber’s hallmark is its resilience. It withstands impacts, knocks, and harsh environmental conditions without compromising structural integrity. The carbon coating also guards against saltwater corrosion and minor scratches, preserving the regulator’s appearance over time. Replacing the traditional thermoplastic front cover with carbon fiber cuts 24 g from the system’s weight—an advantage that feels especially noticeable when the regulator rests on the jaw during extended dives.

Final Thoughts

SCUBAPRO’s MK19 EVO BT/G260 is engineered for reliability in the toughest conditions—cold, contaminated, or high‑pressure environments. Its carbon‑fiber construction, advanced airflow control, and robust sealing combine to deliver a breathing experience that is both effortless and dependable. Dive confidently, knowing your regulator can keep up with the demands of every expedition.
