Hi guys,
Can't say a lot.... but I can show some photos... shot with my new camera from a depth between 300 and 350ft. We use CCR (Close Circuit Rebreather) with constant PP0² and Trimix. We try to remain "light" (carry less tanks with us) so we prefer to use a high Partial Oxygen Pressure (PP0²) in this scenario during peak depth (about 1.5 bar = 21PSI ) to avoid a higher pourcentage of Helium in our gas mix, which will result in a longer deco time. Our narcosis equivalence is around 170/180ft down with air (we are well trained and used to dive with air down 200ft every week)
These are poteries called "Amphora" used Before Christ for wine and olive oil transportation. Certainly grec for sure.
Those pictures shows the complete poteries, one of my banner finds was only a part of it : http://www.treasurenet.com/forums/beach-shallow-water/490097-unusual-find-morning-120ft-depth-30-bc-find-during-scuba-detection.html#post4842937
Without metal detector due to state regulations..and depth! We can't stay that much time down there... each minute spent at this depth = x10 minute of deco time (28' on site = almost 5h of deco time) .... and there is so many eyeballs to enjoy before feeling the need to use MD! ....
... this are only for the Thinnest US Treasure Hunters... and I know you are a lot ;-)
Hope you will enjoy ;-)

A little movie shot between christmas and new year ...
