Thank you for reaching out to us about this, Kai. The Scubapro MK21 / C350 Bundle Set includes both the MK21 and C350 regulators, but unfortunately, it does not come with a regulator pressure gauge. However, the gauge is a very useful tool and we highly recommend considering it as an additional accessory to ensure safe and enjoyable diving experiences.

Can the Scubapro MK21 / C350 Bundle Set handle high water pressure and cold water efficiently?
Imran Hanafiah –
Dear Ling Soo, thank you for reaching out about the performance of your Scubapro MK21 / C350 Bundle Set. The Scubapro MK21 / C350 is designed to deliver reliable airflow under various diving conditions, including high water pressure and cold water. The first stage features a high-flow demand valve and a chrome-plated bar valving system, which provides consistent performance in even the most challenging conditions. Additionally, the MK21’s piston-style first stage and the C350’s high-performance second stage are well-suited to handle the increased density of colder water. Many divers have successfully used the Scubapro MK21 / C350 in cold water, so it’s likely to perform well for you as well. For optimal performance, we recommend following the manufacturer’s guidelines for maintenance and usage. If you have any further questions or concerns, please don’t hesitate to contact us. Best regards, Scubapro Support.
