Hi sandchip ; You are right ; good eye I have dove for many years and ben with people who come back and say something like where did you find that nice crock or in this case pipe , i would remark i was following you and you exposed iy with your fin kick . This pipe i found while tinkering around with a friend's under water camera (i am no photographer ) i was diving with my son and he swam right over it , I was following him and saw the pipe took a snapshot and put it in my goodie bag and here it is among others ..
