Thank you for viewing. This is a TUSA dive computer, IQ1204. It is currently working, so I believe it can be used as is. I received it from someone, but I don't have many opportunities to use it, so I am selling it. There is some wear and tear. Please check the product images. When shipping, I plan to pack it with bubble wrap, etc. Also, please refrain from purchasing if you are sensitive to items handled by individuals.
