Bluewater quarry in B'ham has some nice equipment racks. I don't have any pics of them but maybe somebody does.
They are I'm guessing a 6' by 6' platform with decking on top of them. That way 4 people can gear up, one on each side. They are I'm guessing about waist high. In the center of them is a circle hole so you can stick a large umbrella in the hole for shade. They are pretty nice as you can use them as a picnic table between dives, sit on them, shove stuff under them to get it out of the way (like spare tanks, etc).
anyone got pics of these?
