The Scubapro MK11/C300 had excellent scores in all but the most demanding simulator tests, and very good results in real-world diving. Benefiting from a balanced-diaphragm first stage, two of the MK 11’s four low-pressure ports are high-flow design, increasing airflow 15 percent more than conventional LP ports, which might have contributed to the excellent ANSTI scores. The new C300 second stage is light- weight, and features an Optimal Flow Design valve for increased and reliable airflow and improved breathing effort. Our testers liked the venturi and cracking pressure adjustments, and found both had a solid feel and were easy to use.
With some excellent test scores and a great price, the MK11/C300 is a sweet-breathing reg.
