Good day to all. I've carefully readed your article on CAMNE and, compared with the pictures at the beginning of this thread and your article in the subdrivers forum, a question arises:It seems to me that the exhaust tube is different in the articles mentioned:Here it lloks like there's only one tube with a capilar atop the bag and, on the other, the capilar is in a by - pass with a one way valve. Anyway both seems to end at the tower to let air be caught when the subs reaches surface. Is it correct?Thank you for your info and detailed articles and apologies for my lack understanding.

Kindest regards from Madrid
