Yeah, As I watched the spool unwind I started thinking. Something does not quite feel right here... Lets see, 110 feet deep... 100 foot spool.... that means 100 feet of line... lets see, 100 feet of line minus 110 feet of depth... that comes to -10. Oh crap!! Spool empty and ziiippp! It's kinda like...

Another lesson learned from a different dive: Don't shoot a 30 lb weigh belt to the surface with a lift bag and a 100 foot spool from 110 feet in current. I can personally attest this is not a wise idea unless you want to fly up 10 feet REALLY fast and then argue with a heavy fast moving bag on the ...

And if there’s a current running, perhaps shooting a bag might not be such a good idea. It could just create more separation between you and your buddy as it will provide additional drag that might pull you along in the current faster than it is pulling your buddy … so only shoot the bag if the cir...

Also you need to evaluate if a blue water ascent is wise, or if you are better off going up the shore line. I have had my butt kicked more than one time by mid water up and down wellings that were not present on the bottom (ever exhale and see your bubbles go down?). Consider surface current that is...

An alternative if you loose your buddy and decide you need to do the stop would be to shoot a surface marker buoy so they know where you are...

I think Mr Bailey has a great story about NOT doing a safety stop in all separation situations... I'll let him tell that one. it's a good lesson. Basically, in my mind, the question of doing or not doing a safety stop/deco stop all depend on the situation. 80 feet for 20 min with no current, I would...

Don't think you fully read what I said.

"It was doing a deep dive w/o training, a sound dive plan, or proper equipment. "

At the risk of stirring the pot... I don't think the issue was doing a bounce dive. Or even going deep. Both can be done safely. It was doing a deep dive w/o training, a sound dive plan, or proper equipment. At least from my perspective. (I should probably caveat the bounce dive comment by saying th...

Food for thought, not that anyone needs this to understand an AL 80 is not the optimal choice for a bounce to 200 feet... but it is interesting AL 80 = 80 Cubic feet Typical working SAC rate of a newer diver is probably about .8 CF per min 200 feet = ~7 Atmospheres Average depth for a 200 foot bounc...
