First stage

I haven't got an underwater housing for my camera yet so I'll have to blip a photo of some diving gear instead.

Here's the first stage of my (borrowed) diving regulator. It reduces the air pressure from the cylinder to around 10 bar above the ambient pressure.

Our PADI OWD course fee included two free gear rentals so we rented the gear for the weekend and thought of going for the second dive of the weekend today.
