Precision Buoyancy Workshop
Next to breathing, the most important skill in scuba diving is buoyancy
control. It is also the most neglected. The major point is, entry level
divers in general do not have the ability to execute the precise
buoyancy control that is necessary to execute ascent procedures
prescribed in dive tables and computers. It is apparent that entry level
divers need more instruction and training in buoyancy control.
Butch Hendricks speaking in 1989 at the American Academy of Underwater
Sciences Biomechanics of Safe Ascents Workshop

Hi Steve,
First of all, a very big "thank you" for a most interesting and helpful
clinic yesterday.
To be honest, when we arrived we were not sure what we had let ourselves
in for, but by the end of the day we were delighted that we had!
...
We would thoroughly recommend the course to anyone who is thinking about
it. Money very well worth spent!
Look forward to seeing you again soon.
Regards
Nicky & Barry
Outline
Good buoyancy control is indivisible from safe, comfortable and easy
diving. And it is because good buoyancy skills are so fundamental, but
seemingly poorly taught, that so many qualified scuba divers feel that
they don't really have it together in the water. On every dive they're a
little more nervous than they should be, a bit more worried about losing
control on a wall and dropping, or about not being able to hover at the safety
stop in front of their buddies. They are heavy on their air, so they're
dives are short. They are simply not as comfortable diving as they would
like to be. A well run buoyancy workshop addresses these concerns,
improves your watermanship and makes diving much more enjoyable - which
is how it's supposed to be.
Shooting pictures succesfully inside this tunnel requires excellent buoyancy skills of Mavericks'
Andrew Pugsley. Without them it's easy to bang your head, get caught up in lines and destroy the visibility.
The Precision Buoyancy Workshop is a must for every diver at any level.
I have never before experienced such individual and personal tuition on
a diving course.
The pool facilities are second to none, the depth being a huge advantage
over other venues!
During the day Steve watches and reviews your performance and offers
advise and support that will improve your diving ability.
I have definitely come away with skills that will make me a better and
safer diver.
Many thanks again to Steve and co for an excellent day.

The Diamond Reef Program
The Key To Relaxed Diving
A Mavericks Diving Precision Buoyancy Workshop is a thorough course
that's designed to develop crucial buoyancy skills and explain the
concepts behind them. We've put the Diamond Reef System at the heart
of our precision buoyancy control course. The Diamond Reef is a purpose-designed program for training divers in precision buoyancy control and
pre-dates the specialty buoyancy courses introduced by
major training agencies. Created in the late eighties, it was ahead of
its time then and we believe it still provides, in the hands of a good
instructor, the best learning system available for helping divers
develop consummate buoyancy skills. It's a cross between an underwater
obstacle course and an artificial reef. And it's going to help you learn
a great deal, attain superb buoyancy skills, and have lots of fun doing so.
A review of The Diamond Reef Precision Buoyancy Control workshop appeared in The Independent [link]. The course was taught by Matt Crowther. Matt has been heavily involved with Mavericks Diving from the
beginning. He is the former technical editor of "Dive Magazine".
As with other Mavericks Diving courses, we mix theory with practice. We
believe it is important to understand the reasons you are learning and
applying a skill. Our highly experienced instructors have lots of
background information to share. Steve Warren is quoted in the book The
Art of Diving on precision buoyancy control using the Diamond Reef and
Matt Crowther's teaching of it featured in The Independent. Andrew
Pugsley (AJ) is an expert diver and multi-agency qualified instructor
who presents The Underwater Channel. Each of them is committed to
ensuring you leave this one day course feeling that you've had a really
good time and that you've really improved your personal diving skills.
A neutrally weighted and trimmed diver lazily circles a bommie. Being neutrally buoyant means you don't have to swim hard to generate lift. Neutral trim aids streamlining, reducing the energy needed to swim. Both practices save air and prolong dives.
Safety First
Because Poor Buoyancy Control Can Hurt You
The HSE has noted an increase in diving incidents in British waters.
Lessons learned from the investigation of some of these incidents are
described as 'key elements'. Many of the incidents include loss of
buoyancy control and pressure-related problems
Frank Murray, HM Inspector Diving, Scotland
We'll go over the reasons that poor buoyancy skills and lack of
awareness contribute and cause diving accidents. You'll look at how
incidents develop and get out of control and how to stop them in their
tracks before they can endanger you. By examining in detail real diving
incidents, including fatalities, which involved lack of proper buoyancy
control, you'll begin to understand how to recognise the signs of a
developing buoyancy problem. Most serious diving incidents are not the
result of a single event. Instead, a number of seemingly small problems
that can normally be handled comparatively easily in isolation build
upon one another and combine to become insurmountable. The British Sub-Aqua Club describes this as the incident pit. At Mavericks Diving we
believe that recreational diving is an adventure sport with inherent
risks. They can usually be managed, but never eliminated. We think it is
wrong and misleading to gloss over the risks and this is why we discuss
safety in detail during your precision buoyancy workshop.

Getting Back to First Principles
Because Some Courses Miss These Out
During this workshop we'll challenge some myths and misinformation
commonly held by divers. You'll learn the principles of buoyancy. A
basic understanding of how your buoyancy changes during descents and
ascents will help you calculate how to properly weight yourself and let
you work out need-to-know information such as does your BCD provide
adequate lift for the dives you make, for example.
You'll work on lots of practical skills all designed to help you
thoroughly master buoyancy control. We'll begin by showing you how by
weighting yourself properly you can actually dive without any air
in your BCD. In entry level classes it's common to overweight students
to help them stay in one place (on the pool bottom) and not drift
around. Unfortunately, this is often not explained and divers leave the
course thinking that it's okay and normal to be overweighted in open
water. It really isn't. Many experienced divers still get it wrong.
Steve and Andrew (AJ ) will show you how to get this basic
requirement absolutely right.
A relaxed and competent diver doesn't depend upon arm waving to keep their position in the water column.
It's Not Just About Neutral Buoyancy
You Need Trim Control Too
Water is 800 times more dense than air - that's why you can float on it. It's
also why it creates such resistance to moving through it. Our Mavericks
Diving Precision Buoyancy Course will teach you how to achieve neutral
trim to make you streamlined and help you move through the water with
minimum effort. You'll practice distributing your weight to achieve
exactly the trim you want in the water. By moving your weights around
your body, you'll find out how you can easily change your attitude in
the water. You'll work with integrated weights, conventional weight
belts, BCD trim weights, weight harnesses, ankle weights and learn how
to use your tank as a balance weight. Being properly trimmed makes you
much more streamlined and will significantly decrease your air
consumption leading to longer dives. In the pool you'll discover how
vital proper trim is to being a good diver.
Ascents and descents need to be something you can precisely control. Mavericks Diamond Reef buoyancy clinics focus on these and many other key buoyancy control techniques.
Ascents, Descents and Hovering
Essential Skills On Every Dive You Make
The average diver today cannot control his rate of ascent. We have
confirmed this from several sources here today. The average diver cannot
learn how to control his rate of ascent because there is no mechanism or
method within the field for them to acquire this training or education
or to practice this skill. It simply isn't there.
Dick Long, American Academy of Underwater Sciences Biomechanics of Safe Ascents
Workshop, 1989.
Ascents and descents are part of any dive - and also prone to problems.
In open water you could be on a wall or in the blue with thousands of
metres between you and the seafloor and you really want to stay in the
top bit. When ascending without a line, you'll also want to be able to
precisely control your ascent speed. You'll practice using breath
control and your BCD to achieve safe ascent rates and descent rates
without kicking.
You'll also work on your hovering skills, vital to making safety and
decompression stops. You'll learn to pause and hover at any point to
halt a descent or ascent. These skills are valuable for protecting your
ears if they stick on the way down and for reducing the risk of
decompression illness and lung expansion injuries on the way up. We'll
throw in mid-water delayed marker buoy deployment as well - if you
haven't learned how to do this previously, it's a very useful added
value of the Mavericks Diving Precision Buoyancy Control workshop.
Divers are often taught to vent air through their BCD oral inflator. This usually lets water back into your jacket. Dump valves largely prevent this.
Spatial Awareness
Learning To Be a Friend of the Reef and Not a Reef Wrecker
Good buoyancy control is a combination of knowledge, attitude, skills
and equipment. All of these are taught during a Mavericks Diving
Precision Buoyancy Workshop. Another essential part of your course is
developing spatial awareness. Your fin tips have no nerve endings, so if
you kick a one hundred year old hard coral, you're likely to kill it in
an instant and you won't even know you've done it. A careless fin kick
inside a wreck or cavern can turn good visibility to absolute zero in
seconds. A stray pressure gauge or alternative air source can drag along the reef
like a wrecking ball damaging both it and the coral. So we'll put a lot
of time into developing your awareness of your own profile, your
surroundings and your possible impact on them. Good spatial awareness
and perfected buoyancy skills mean that you can safely get very close to
your subject with a camera, for instance, yet exit the water with super
images and leave the marine environment undamaged.
Trim weights can be fitted to many BCDs. They help keep a diver horizontal, improving stramlining and reducing drag. One result is you'll use less breathing gas and so can enjoy longer dives.
Manoeuvrability
Putting You In Complete Control
Dolphins can't swim backwards.vScuba divers can. Sometimes. Being able
to move backwards is a great skill to have. It can let you back out of a
hole you shouldn't have entered or move safely away from a delicate fan
coral while holding your camera and framing the shot. Some fins are
better for this than others, so we'll have a few types available for you
to try. You'll also practice hand sculling techniques that let you
subtly change your position in the water column with minimal effort and
little thrust. These skills are less disturbing to fish and you are more
likely to be accepted by them and allowed closer for observation using them.
Wall diving requires precise buoyancy control if unplanned, and potentiually dangerous, descents into deep water are to be avoided.
Self Rescue
Buoyant Ascents Can Save Your Life
Many divers are concerned that a buoyant ascent, achieved by dropping
weights or inflating BCDs is highly dangerous. At Mavericks Diving
we'll explain some of the issues surrounding this self rescue technique
and why fast, buoyant ascents are a proven way to reach the safety of
the surface. And we'll demonstrate them in the pool before letting you
take a turn.
A good diver can easily hang effortlessly in mid water. This avoids unplanned contact with the seabed---or animals that can fight back.
Diver Rescue
Controlled Buoyant Lifts Can Save Your Buddy
You'll practice making a rescue lift on a Simulaid manikin using,
alternatively, your own BCD and the casualty's to bring you both to the
surface. This exercise will demonstrate some of the problems of
overweighting by either diver in a rescue situation.
divers (the program Andrew and Steve teach at Mavericks) require
students to learn this technique and in-water resuscitation methods (
). If you haven't learned these skills, Andrew and Steve
will be happy to teach you during your Mavericks Diving Precision
Buoyancy Workshop.
Wings type BCDs are preferred by some divers because they leave their front unecumbered. Wings are often preferred for technical diving but may be less suited to single tank sport diving.
Once you've cracked the basics, it's on to practice more advanced
skills. We want you to fully appreciate how seemingly subtle changes to
your weighting can have a huge impact on your buoyancy. So we'll get you
mask clearing while hovering, picking up items of different mass and
swimming them through the diamonds as well as playing pass the weight
around..... Every game is intended to refine your abilities.
You'll try some different finning techniques, learn finger walking, use
a reef hook and deploy reels and lines through a tunnel of diamonds.
You'll even fly a high speed diver propulsion vehicle through them too.
Learning's best when it's fun!
You'll play our underwater version of The Gun Run: moving an
outboard engine through the Diamond Reef Assault course using lifting
bags without ever touching the bottom or breaking the surface.....
A Mavericks Diving Precision Buoyancy Workshop is much more
comprehensive than many other similar sounding programs. We include many
more extras - they might sound small but on your next dive they'll make
a big - and positive - difference.
