Do you want to improve your buoyancy skills?
In this video, Eva and me demonstrate 2 common buoyancy mistakes and how to fix them. You
will first learn to keep your buoyancy under control when you descend. Then, you will see
how to sort out emergencies in case you lose control of your buoyancy on your way up. Especially
at the safety stop. If we never met before, my name is Patrick, I’m a diving instructor
and co-founder of Air Consumption Scuba. My goal is to help you refresh and upgrade your
diving skills. On this channel, I give you tips and tricks to improve your air consumption,
get ready for your next diving holiday, and take your diving skills to the next level.
I want you feel comfortable for the first minute you hit the water again. If you are

do underwater. Let’s start with your wetsuit. Most wetsuits are made of neoprene. Neoprene
is a flexible material that contains tiny bubbles. The deeper you go the less buoyant
your wetsuit is because these bubbles get squashed. So if you were neutrally buoyant
at the surface in your wetsuit, you will most likely be negatively buoyant when you reach
the deepest level of your dive. If you don’t put air in your BCD, you will continuously
hit the bottom, maybe even hurt yourself and the aquatic life, or struggle to maintain
your depth if there is no bottom. If you don’t pay attention it’s easy to fall far deeper
than you should. Then you have to kick up. Your breathing rate starts to speed up because
of the physical effort, stress and maybe even anxiety. This will empty your tank faster.
As you are at the deepest level of your dive profile, you can easily waste ⅓ of your
air supply in a couple of minutes… How can you avoid this? Simple … and easy too…
Press on the magic button gradually while you descend to maintain neutral buoyancy.
Towards the end of the dive, when you start changing depth and slowly make your way shallower,
divers with less experience often forget to vent air out of their BCD. When you descended
to the deepest depth at the beginning of your dive, you added some air to your BCD because
your wetsuit lost buoyancy, right? If you put air in your BCD at 30 m, remember this
air will expand on the way up. Back at 10 m the air in your BCD will have doubled. This
is when you sometimes see divers rising slowly up towards the surface like hot-air balloons,
or like magnets slowly attracted to the surface. They just lost control of their buoyancy.
When this happens, they usually try one of two things: They either press the deflate
button on the inflator but surprise surprise … No air comes out. In this situation, the
air is trapped at waist level in the BCD. Air always heads upwards, vertically towards the
surface. Or they start to kick and swim downwards with their hands, head first. Neither of these
2 options will fix the problem. If you forget to vent your BCD gradually on your way up
and you lose control of your buoyancy, don’t waste time:
Either move your body so it’s nice and vertical. Slightly leaning backward is even better.
Grab your inflator, extend it and hold it slightly backward as well. Press the deflate
button and empty your lungs all the way but don’t hold your breath.
Or do this: stay head down and kick downwards. Use the release valve on the right hand side
at the back of your BCD. This is why you should always get familiar with the equipment you
use and why you check it works well… Adjust the air in your BCD each time you change depth.
Remember, your lungs are your best Buoyancy Control Device. Use your BCD when your lungs
can’t do the job. Find the right balance. Use your BCD moderately. In this video, Eva
