SCUBAPRO regulator set - Brand: SCUBAPRO - Model: S620 - Color: Black/Yellow - Accessories: With gauge - Features: Ergonomic design - Highlights: Pink grip Thank you for viewing. Last used: August 2025. Functionality confirmed. Overhaul not performed for several years. The regulator mouthpiece is a generic product. Replacement is recommended if you are concerned. The compass on the gauge has some sand in it, but it works. I think it just needs to be cleaned better. It works normally underwater. It shows signs of use, but it's still a usable regulator. I do not know the specifics of the equipment, so please check the manufacturer's website. Everything shown in the photos is included.
