Description
The MK11 EVO/S270 regulator combines a balanced diaphragm first stage with a compact S270 second stage to deliver consistent air flow for scuba diving. It maintains smooth inhalation and reliable performance across depths, tank pressure, and varying breathing rates, making it a dependable choice for diving in a range of underwater environments.
Designed for versatile gear setups, this regulator is compatible with Yoke or DIN connectors, supports Nitrox mixes up to 40%, and balances performance with comfort across warm, cold, and temperate waters. Built to endure diverse scuba conditions, it integrates durable materials and precise engineering for reliable operation in the field.
