[Junk Item] The SCUBAPRO Xtender Quali-o is a high-performance dive computer specifically designed for diving. - Brand: SCUBAPRO - Model Name: Xtender Quali-o - Color: White - Functions: Dive Computer Thank you for viewing. I used this for a long time, but I've stopped using it since I bought a new one. The battery is dead and I can't confirm its operation, so I'm selling it as a junk item. I don't know if there are any usable parts, but I hope it can be of use to someone who understands.
