I received this as a thank you for helping out my diving instructor. ...However, I haven't used it even once, and about two years have passed. Since I already have another dive computer, I don't think I'll ever use this one. The battery was replaced, but it's about time for another replacement if we consider a 2-year cycle, so I've lowered the price from the original listing. The instructor used it about 3 times, so I'm listing it as "like new." The box is dented, but the contents are clean. It's very expensive when new, so if you were looking for one, or wanted one, please buy it for the upcoming season!! I'm not considering selling individual items at the moment. It comes with a warranty, so it's a genuine product. I can add more photos if you message me!
