What is the depth limit for the UBA MK 20 Mod 0 and 1 when used in SCUBA mode?

The UBA MK 20 Mod 0 and Mod 1 have a designed operational depth limit in SCUBA mode of 190 feet of seawater (FSW). This depth limit is determined by several factors, including the specifications of the breathing gas system, the structural integrity of the equipment, and the physiological considerations for the diver.

When diving beyond this depth, the diver may experience increased risks related to narcosis and oxygen toxicity, as well as potential equipment failure due to pressures beyond the manufacturer's specifications. The 190 FSW limit reflects a combination of safety standards and performance criteria established by diving operations, ensuring that divers can perform their tasks effectively while minimizing risks associated with deeper dives. Thus, understanding and adhering to this depth limit is crucial for the safety and success of diving operations using the UBA MK 20 Mod 0 and Mod 1 in SCUBA mode.
