Wetwork for Hire
That reminds me of something: when we started diving my wife got a Mares Puck dive computer. It was supposedly brand new, in a sealed original box etc, but came with a few dives already logged (!). It was cheap and at the time where I was living it would not be economical to ship it back, so we ended up keeping it.
I don't know if this is considered normal with other brands, but since then I took the decision to discard Mares for life.
It came with logged dives because it was factory tested to guarantee you didn't receive a non functioning computer. Not because it was used.
