I recently bit the bullet and purchased a Spare Air 6cfm bottle by submersable systems inc. and was wondering if anyone had any problems with theirs or what their opinions on them are. I have done over 15,000 shallow freshwater dives in the Tennessee River as a commercial diver and would never use it there, but it seems like every time I go to Florida or in the ocean for that matter and dive with "UNFAMILIAR DIVE BUDDIES" on dive charters, they wander off while I am looking at something or taking a picture even though I stress the importance of staying together during predive planning. I have had several dreams where I have been at depth (80+ feet) and had an out of air emergency and my dive buddy is nowhere to be found. I am very, VERY comfortable in the water but have a great deal of respect for its abilities to harm me. Am I over reacting or just being a responsible diver?
