This is a Reyson regulator for scuba diving. I purchased it about 10 years ago and have used it for about 100 dives. I've had it serviced several times during that period, but haven't used it for about 2 years and haven't had it serviced recently. Overall, there is a feeling of use and aging. The name of the dive shop where I purchased it is written on the 2nd stage and octopus. The items to be sent are those shown in the photos. A medium pressure hose is also included. Please have it serviced before use. Please understand that this is a used item and that the inspection is done by an amateur before purchasing.
