| Imported post <font color='#000080'>If it's good for long deep cave diving, couldn't it do for long deep wreck diving too? How deep do you mean? I was thinking about a gas extension tool for 40-50m dives, where twins is all well and good, but I'd rather be on smaller tanks on my back, and with much less restriction on dive time. I suppose by the time I've put twin 7s either side of it it's the same size as twin 12s. Anyway, I was just thinking about different options, as I'd not seen this one before I fancied canvassing a bit of opinion. |
