My wife and I have been talking about using an AL 40 as a redundant air supply on some of our deeper dives. Not as stage bottles only for emergency. Have dove doubles and have a set but some boats just too small or not welcome for doubles. We dont want the bracket or anything like that on our tank but to sling it on the side seems the way we want to go. Any do's or donts? when getting tanks or rigging the bottles.
Thanks
