NAS Excavation Course
Not a very complete set of pictures as I normally had my hands full.

These first pictures are the Water Dredge. THis is driven from the little water pump and is a whole lot less fuss but not really as much fun as the Air Lift.

A bunch of general shots of people doing diving things. This is Zone 1 at Horsea Island. Perhaps not the most exciting place to go and with no current what so ever you get to keep any silt you kick up (or the guys adjcent to you kick up).

...and finish with the surging waters of the AIr Lift.

The pictures can be accessed by clicking the thumbnail but they tend to be 900K+ files
