What's pin depth?

What's the term "pin depth" mean? I've seen a few places state the pin depth of a dive.

I hadn't heard (or noticed) that term until reading your question.

Googling it, I see that it appears to be used to describe the depth at which permanent mooring balls have been "pinned" to the reef. In other words, if you follow the mooring line down to the reef, you'll be at the "pin depth," though the reef may get deeper elsewhere around the pin.

I've never heard it called that before. Sounds like it refers to mooring depth, which I would think is a more common term referring to the same thing. You can be moored in 90' of water and have a 3000' wall next to the "pin" depth.

I believe the term comes from England/Scotland. When a boat ties off to a buoy the Scottish call it a mooring pin.
The first time I heard it was on Grand Cayman. Our DM was from Scotland and as we went into the water from the boat he said "meet you at the mooring pin". We all gathered at the bottom of the buoy that the boat was tied too.

interesting to say the least.

I can see where bottom depth would be pretty irrelivant on a 3000' wall

Ditto for the oil rigs, in most cases. They don't tie up, though, so there's no mooring line (or pin).

Damn! I always thought they were saying "Gin Depth"... so I'd take my flask with me....

I saw the term myself while researching dive sites on Grand Cayman

Thanks for the help everybody
