The Scubapro MK11 EVO R105 Dive Regulator is a simple, rugged air delivery system for scuba divers. It pairs a compact first stage with a dependable second stage to perform reliably in a range of diving conditions. The MK11 EVO first stage features a chrome-plated brass body and an air-balanced diaphragm design for stable performance across water temperatures.

Designed for practical underwater use, the chrome-plated brass first stage includes forged brass construction with metal fins to improve thermal exchange and plastic bumpers to resist scratches. A double spring layout enhances performance while keeping the assembly compact. Two high-pressure ports are positioned at a 15-degree angle for clean hose routing, while four high-flow low-pressure ports expand airflow and routing options. CE Certification under EN250A confirms cold-water performance.

The R105 second stage employs a classic downstream valve for smooth, dependable airflow. It features a durable metal valve housing and an anti-scratch front cover to withstand rugged diving environments. The system is suitable for Nitrox up to 40% and is designed for warm, cold, and temperate waters with an INT connector.
