Ok... this has me puzzled...
1: Could you explain "hiding" behind a bunch of gear?
2: Couldy you explain how your "skills" have improved? ... and why you
couldn't have "improved" your skills with a... ummm... *conventional* rig?
This is an easy one.
Todays standard gear in 99% of the dive shops is gear designed to make up for a shortfall in strength and skills including mental skills; the industry want's to include a very wide cross section of people in diving so they design gear that makes up for a general lack of skills and comfort level. More people in diving = more sales. Big overstuffed jacket bc's with huge amounts of lift buoy divers out of the water on the surface so their nice and high up and feel safe. When in reality these contraptions mask the issues of weighting and surface comfort and actually reguire way more weight than is necessary just to make them work. Not to mention trying to move one of those things through the water. This is why they came up with split fins. Split fins make it easier to fin kick but in my opinion to the detriment of top speed, power, and manueverability. But people generally are to lazy to develop the leg power to effortlessly use an old school tried and trued rubber fin.
With weight integrated BC's it's worse. The air cells are way to big and the reason for that is because the rig has to be able to float not only a potentially very large steel tank but also all the integrated weights. The result is a huge bag of air that restricts the slipstream so bad that divers typically trudge through the water not glide. And in the bouyancy critical zone (10 to 30 feet) the air cell is so big that the diver constantly struggles to hold a position because of the expanding and contracting gas in the cell.
These dry snorkels now days don't let a diver suck a little water and prevent the diver from ever learning to relax and to clear and use a simple J tube. Using a J tube is more difficult at first but with this learning curve comes skill and confidence, as with all other minimalist gear.
I don't see a way to fully refine skills and reach ones maximum skill potential using contraptions that don't expose a diver to his/her weaknesses.
My skills have improved because shedding much of this fluff has increased my agility and speed. With this new gained speed and agility different finning techniques can be used that would be difficult or impossible using conventional gear such as smooth porpoise finning - very sleek and very efficient. Body positioning changes because of the added speed and you learn to use your whole body as rudder like a pinniped.
The skill level is largely mental, but also because the gear is so minimal the diver must learn a whole new set of skills like perfect weighting, lung control, body positioning and slipstreaming.
It's like driving a car that will only go 50 miles and hour around a track, you will not need to know the skills of how to drive 150 miles an hour because the car you're driving can't go that fast. But when you get into a car that can go 150 MPH a whole new set of skills needs to be learned. Is it less safe to go 150, yeah probably, but with the learned skills the risk is minimized and it's a hell of a lot more fun!
Minimalism isn't for everybody that's for sure. I wouldn't recommend it for someone who has difficulty getting comfortable in the water, but wants to dive for peer or spousal pressure reasons or part time vacation divers, etc. For them I would say just stick with the regular stuff and have fun.
Personally I find minimalism a challenge both mentally and physically and this is what turns me on, this is my kool-aid, and ultimately my bliss.
I freedove for years before doing scuba, and from this stand point I can see how scuba developed and later got buried in a sand storm of crap.
Skin diving was the original ocean diving activity. Skin diving is 100% skill. weighting is perfect, strength is there, stamina is there, mental fitness and relaxation skill absolutely has to be there.
They simply added a tank and a breathing aperatus and continued on with the same set of impecable skills. This is minimalism in a nutshell.
I should also mention that diving minimalist I am able to use my long blade freediving fins. This not practical with the big poofy contraption gitups.
You talk about speed! holy man!
