SAS Diving Regulator Due to long-term storage, it has not been used for 20 years since its last overhaul after use. Please be sure to have it overhauled before use. The regulator and the back of the case have names written in Roman letters with a fine black marker. Used approximately 100 times overseas only. Overhauled in Japan. I am also selling other diving equipment. The price is set considering shipping costs, but if you wish to purchase multiple items, I will offer a discount, so please leave a comment. Thank you for your understanding of the above, and for your purchase of a used item with no claims or returns. Thank you for looking.
