Disclaimer: Reading the the following paragraphs please keep in mind that, I do not promote diving alone, I recommend nobody dive alone!
I dive alone 98% of the time, because of the buddy situation and the fact that most freedivers that I have come across do not spend much time enjoying the life that flourishes beneath. The most captivating aspect of freediving for myself is the experience of the underwater "world" and it's diversity under the craftmanship of nature. I discovered life under the sea alone and I suppose it will continue that way.
However, I really think there is a misunderstanding to the whole idea of alone/not alone. Most freedivers in these parts are competitive freedivers and that is how they were introduced to the activity. Therefore of course it is essentially required to be with a buddy if you look at it from the angle that you are participating in a competitive activity that you will push your limits in. They perceive diving alone as reckless. Diving is just training in general for these people, and training tends to have strict requirements in many ways, which puts most people into a flexible state of mind as far as when they will participate in the activity. So the reasoning keeps coming up that it is reckless since you could wait until you have a partner. What makes them think one can wait or that one can not dive? They have not found diving the same way as many others.
Now if we erase that perspective from our minds and approach it as an activity discovered out of passion for the experience of the environment below, you have no choice but to compare it to all other activities of the same nature. Under this perspective you would have to admit that almost every activity of outdoor passion/interest has a heightened possibility of injury/fatality when compared to inactivity. And by adding a partner to each of these activities we decrease the risk, although we do not rid ourself of the possibility. So do we stop going on scenic drives alone? Do we stop hiking alone? Do we stop going for a walk on the street? Do we stop riding a bicycle in the forest trails alone?
The answer I am certain is individual and dependent upon our own philosophies/beliefs/approaches to life. But it must be obvious that all of us partake in activities where we could choose to only take part when a partner is available, at the cost of something else, and yet we still do it alone. Generally most people are not even aware of the dangers involved in more than half of the activities they take part in daily. Sometimes we ascertain a concept of risk, we weigh this against our interest, we weigh it against our beliefs, and we decide whether this feels right for ourselves. Therefore, I personally think it is hypocritical to draw a sweeping conclusion for everybody of what is the correct/sane/best approach. It ends up being very personal. The cost to most of us who dive alone to change to a lifestyle of diving only with a partner, is a loss of experience for something that heightens our appreciation for life. And doing so would only be towards avoiding a possibility which is inevitable sometime anyhow. Not knowing when death shall greet us, but certain it will, is part of the nature of our existence.
Even the solution to safety presented is rather inconsistent. Buddy system slightly increases the chance of survival in the local waters of BC. Why? Waters can get murky here and are very dark looking down. So if you have a SWB and float to the surface and have not already drowned and your partner is close enough to respond in time and your partner keeps your airway free then you have a good chance of survival. Now what does this say to us about the adamant proclamation that diving alone is not ok, yet diving in these waters with a buddy is wonderful. It says that all the freedivers, alone or not alone, are taking part in a risky activity. They are all as sane or insane as each other. At what point does a slight safety enhancement make an activity ok to take part in? Whereas without that slight enhancement it is foolishly ridiculous and irresponsible? What are they going to say when a non-diver claims the same about them!? Because from the non-diver's perspective the "safe" freediver is not so safe and is taking unnecessary risks!
So when somebody informs me that they stay home all day waiting for life to end, but very safe in the meantime, then I will feel the challenge of a decisive, consistent approach. But until then, all I see is people who have drawn their conclusions very rigidly for one activity, while not applying the same concept to every other activity and decisions in their lives, maybe unaware of the relations in other aspects of their lives.
My point being that so many of us are posting here that we are "guilty", which implies in general that it is prevalent that we are doing something we are not supposed to. I think it is the complete opposite. We should not feel guilty for living and exploring why we are doing so. We should feel guilty when we let our fear and other's dictate what should and should not be done. I say be proud that you believe in life and make sure to explore your true reasons and understandings for your participations in life's possibilities.
Please do not mistake me for trying to promote diving alone. I would say to everybody "do not dive alone", but if you do, know why you are doing so and what is involved. Just as I would recommend to think about why you jump into a car and drive around so confidently, alone or not. Doing so for myself has led me to lessen the amount I drive, recognize when I am responsible for my passenger, and make sure I know what it means for me to take part in driving.
As usual an expected 2 paragraphs grew... :head
PS. Actually I often wonder if I have not already drowned while freediving and I just think I am alive. Would I know when I had left the world? Would it matter?
