What is used for dry suit inflation on the KM37?

The use of the low pressure port for dry suit inflation on the KM37 is essential for maintaining the divers' comfort and buoyancy control while underwater. This port allows for the introduction of gas into the dry suit, keeping it inflated and providing thermal protection to the diver in cold water environments.

Using the low pressure port is necessary because it operates at a lower pressure, making it suitable for the task of inflating a dry suit. This enables divers to easily manage their thermal protection and control buoyancy without the risk of over-inflation, which could cause complications or discomfort.

The other options do not serve this function. The high pressure port, for example, is designed for providing the primary breathing gas to the diver, not for suit inflation. The inflation valve is a component that allows gas to flow into the suit but does not specify the pressure being used. Similarly, an emergency gas supply is intended for providing additional breathing gas in case of a situation where the primary supply fails, rather than for dry suit inflation. Therefore, choosing the low pressure port is appropriate for dry suit inflation in the KM37 system.
