Capespearo - I notice the wording under you post "You guys are going spearfishing ? But where are are your tanks ?
". I had a fisherman ask me (on Saturday, on my way across the rocks to the water) how much air / airtime I had in my float and how long can I stay under with the air in the float - so I stupidly start to say it is a 5litre (I think it is) float, then I said a minute or two. I just left it - some people (without being nasty) just have no idea how it all works.
