Esom, your assertion that diving without a buddy is less safe if the diver has been warned of the danger is... absurd.
Why are you arguing this?
Similarly your repeated claim that the semantics of the term free-diving (e.g. whether it includes or excludes diving without proper safety) is a saftey issue.
Or have I misunderstood? Your posts seem wilfully obtuse and I struggle to understand or assign meaning to them.
I'm not picking a fight, just being honest. This is, after all, a matter of life and death.
I agree - Esom seems to be making the argument that to be conflicted about the activity somehow makes one accident prone. I can understand this kind of thinking - but I do not agree with it.
On the other hand - among the things I disagree with in this thread are some of the comments about 'making us all look bad'. My instinctive reply to this does not belong in this context. Freediving is something I DO. Your values and judgements alluding to my needing to conform to your expectations are something best kept to yourself - be they 'reasonable' expectations or not. I do this to relax, not to satisfy your criteria.
Personally I am normally much less relaxed when diving with a buddy. This is because I am usually the most experienced diver and feel responsible for them. However - when I am diving with very competent divers (like Connor) I feel very relaxed and have even more fun.
My first Ice dive was with scuba divers - I was the only free diver and was invited to join them on a wreck beneath several feet of ice and in about 15 meters of water. I did not get to stay in as long as I'd've liked to (small hole) but it sure was fun.
I train here almost daily in a community pool. I know the lifeguards and I have designed my workout to be easy for them to track and well within my limits. I've also tutored them all in SWB rescue, explained precisely what I am doing and I never stop moving. I don't do anything intense without a trained buddy and a very quiet pool. I frequently encounter people training to be SEALs, air force or Coast Guard rescue. Typically upon seeing them swimming underwater I immediately coral them and impart the basics. The lifeguards know they are not me and its not likely to reflect on me if they black out. (in fact, one did - coast guard rescue swimmer (hadn't spoken to him). I tell the lifeguards stuff like "don't let them do that"
The vast majority of freediving fatalities are spearos. The reason is obvious - they have an intense focus outside of their bodies. A good many of them have died while diving with others.
At the risk of contributing to your delinquency and making myself a social pariah - here are three suggestions:
Make a point of dividing your attention when you are spearfishing - so that part of your mind is ALWAYS monitoring your state. Make a rule to just let go of the situation, whatever it is, when it's time to go up. Let the fish go, or whatever. I do free dive photography and have bailed on innumerable perfect shots because I've made a rule.
Generally speaking neither I, nor anyone I've trained, dive into contractions - with or without a buddy in the immediate area. That said - some people just don't get contractions, or get them very late.
Don't compete with your last dive - or with the last day you dove.
Don't use ideas like 'I can go x amount of time more after contractions'. Such an idea is remotely applicable only in statics.
Freediving Solo is obviously more dangerous than diving with a competent buddy. But I'm not going to give you some righteous monologue about social responsibility to try and guilt you out of doing it. The only mitigation is to be thoroughly educated and experienced. There are no guarantees.
