I was afraid to post this on the diving board....there is only 2 posts on it...i'd be waiting forever.<br /><br />Does anyone know how to build a thrid lung setup for shallow diving.<br /><br />It would be nice for scallops and spearing some snappers (hog)?<br /><br />Heck....it would just be fun to use.<br /><br />Lots of stuff to see in the gulf round here.<br /><br />Shadywood.
