A legendary diving computer. Production and after-sales service by the manufacturer have already been discontinued. I've used it for many years, but it was left with a dead battery for several years. I replaced the battery in 2022/12, so depending on the number of dives, I thought it would last for nearly 5 years. However, the battery died again after about six months. I think it's probably reached the end of its life. I'm offering it to someone who is okay with that. Operation has been confirmed. The body is made of titanium. There is no case or instruction manual. Please find them online. Nitrox compatible.
