Most of the time do you think the buddy you dive with is oblivious of you? Do you find yourself finning hard to keep an oblivious buddy in sight? Is your buddy a bottom groveling shit kicker? If you dive solo with or near strings, ropes and shot lines etc., you better know how to remove your kit and refasten it. You may eventually find out that you would rather dive without danglies as underwater entanglement solo is an alarming experience which you must be able to cope with. The only problem I find with being a totally solo diver is back zips; no problem to undo, but they tend to catch in the undersuit when your trying to zip them up.
