Squad! At ease for your Scuba Diving Refresher Tips. Ok, here’s the deal: Do you ever find yourself unable to recall vital scuba diving knowledge?
Or perhaps you need a Dive Gear Checklist to remind yourself of what you need for Scuba Diving and how it all works!
Whatever scuba gap in your scuba knowledge has bought you here: Fear the scuba not.
We completely understand how daunting it can be to Dive – or Back Roll – back into to the World of Diving after an Extended Break.
It’s for exactly that reason that Diving Squad has compiled these Scuba Refresher Tips to help get you back up to speed and ready to join scuba missions in no time!
Ok Squad – Let’s Dive In!
Alright – here we go: The first of our Scuba Refresher Tips is a breakdown of the 5 step Scuba Buddy Check that you and…a buddy (shocker!), give eachother right before a dive.
The PADI dive check doesn’t condense down into an easy diving acronym, but there’s hope! Diving Squad folks like to think that Breathing Water Really Ain’t Fun.
Let’s see that Diving Acronym one more time:
Breathing (BCD/ Buoyancy)
Fun (Final Check)
Check to make sure the BCD is properly connected to the air supply, and practice inflating the vest to ensure adequate airflow.
Also, test deflating the vest to ensure the purge valves are in good working order.
Make sure any additional weights are fastened securely inside the weight pouches.
If you’re buddy is using a weight belt, make sure it’s secured and cinched properly to keep the weight from inadvertently detaching.
Check to make sure that you and your buddy can easily access and operate all the release catches for your vest, tank, and weights.
This will allow you to easily slip out of your BCD in case of entanglement or an emergency, and assist your partner if need be.
Check that the air valve is completely open, and all tubes and valves are secured in their respective places.
Take a few deep breaths from your regulator to verify proper airflow and taste. Repeat this process for the spare regulator.
5. Final Check
Strap on all your additional gear and complete a head to toe check to make sure absolutely everything is secured in place and not posing an entanglement risk.
And there you have your 5-step Scuba Buddy Check procedure: an integral part of our scuba diving refresher tips!
But before you go charging off into the ocean, reign in your seahorses and consider these next few points regarding in-water procedures…
Communication with the rest of your Diving Squad is crucial! Whether you see something interesting, are having difficulties or are running low on air; you must be able to make yourself understood to your diving companions. How?
Through the use of Diving Hand Signals. You were undoubtedly taught a few of the Scuba Hand Signals signals during your Open Water Course, so let’s take a couple of minutes to blast through them:
OK (Underwater): Touch your thumb and index finger together to form an O while keeping your other three fingers extended.
OK: (Surface): Touch the top of your head with your hand, either open or closed and form an O shape with your arm.
Ascend: Thumb up.
Descend: Thumb down.
Stop: Extend hand straight out in front of you (like a traffic cop stopping traffic).
Turn the Dive: Make a circular motion with your index finger.
Problem: Wiggle your hand in front of you. Similar to a so-so sign in standard conversation.
Equalizing Trouble: Point at your ear
Low on Air: Place a clenched fist across your chest
Out of Air: Make a slashing motion across your neck.
I’m cold: Cross arms as in the traditional ‘shivering’ motion.
How Much Air Left? – This signal means someone is asking you how much oxygen you have left. (Which you can find out by looking at the pressure gauge!)
100 Bar’s of Oxygen Left – Make a T with your two hands if you have at least 100 oxygen. For every additional 10 bars of air hold up one finger after this signal.
Look at Me – This is when someone, usually your instructor, wants you to pay attention to them so they can show you something.
As all of us at Diving Squad have learned, the trick to fully utilising these Diving Signals is making sure you have your buddy’s attention so that they can see what you’re doing!
It’s so easy to leisurely drift along, obliviously singing The Little Mermaid’s “Under the Sea” in your head, and be completely oblivious to your Squad Mate’s frantic attempts to communicate. Trust us…
…But we do have a crafty way to overcome this. If you can’t get your buddies’ attention, simply use a tank banger noise device to do so.
These devices consist of a hard object being secured to either your hand or tank; all you have to do is lightly bang it against the tank to make a very noticeable sound and attract attention to give the Scuba Signal Presentation of a lifetime. Bada bing Bada Spalsh.
One of the most memorable sensations of Scuba Diving is feeling the pressure start to build upon your ears and the satisfaction of being able to equalize that pressure in order to bring them back to normal.
Without the ability to do this, it’d be totally unfeasible to dive deeper than a few meters.
Scuba Diving Equalizing is therefore a pretty vital concept to include on our Scuba Refresher Checklist! Let’s recall why your ears start to hurt underwater in the first place:
You ear canal, or outer ear, is connected directly to the environment, but the space behind your eardrum – known as the middle ear – is not.
That’s why a pressure difference is created as the pressure in your outer ear increases with depth but the pressure in your middle ear remains unchanged.
It’s all because it creates an uncomfortable feeling that can easily lead to pain and ear damage if the pressure is not equalized.
We are given several tricks to help equalize this pressure as we descend and head off any discomfort before it materializes. So, let’s now review a few of those tricks:
This is the most common diving equalizing method and is probably what you were taught during your open water course.
Simply pinch your nose and try to blow. This will cause a pressure buildup in your mouth and nose that forces open the Eustachian tubes that run from the back of your throat to the middle ear, allowing the pressure to equalize.
However, the nose pinch method isn’t infallible and doesn’t utilize the muscles that are already present in that area to open up the eustachian tubes. Take a moment to familiarize yourself with these two additional methods so you have backups!
Swallowing engages the muscles at the back of the throat, opening the eustachian tubes, and can often work to equalize your ear pressure all on its own.
For an added boost, try pinching your nose and swallowing at the same time. The swallowing will open the tubes while pinching your nose will cause a pressure increase and force air into them.
Working your jaw also engages the muscles in the back of your throat to aid in Scuba Diving Equalizing.
One of the most effective methods we’ve found is to tense the muscles in the back of your throat while at the same time pushing your jaw forward. Like swallowing, this will open up your eustachian tubes and allow the pressure to equalize.
Diving Squad’s top advice for scuba diving equalizing? Equalize early and often. Begin trying to clear/equalize your ears before you even start putting on your gear, and equalize continually while descending.
Most importantly – and one of our most import scuba diving refresher tips – If you start to feel pain or discomfort, don’t try to simply power through it! Ascend slightly, equalize, and then continue your descent.
Equalizing problems didn’t get its own hand signal earlier for nothing! Let your partners know if you need to descend more slowly or take an equalization break!
Have you ever noticed how your more experienced Diving Squads mates posses the uncanny ability to control their air consumption and make their supply last much longer than yours? This inevitably leads to you being the one to turn the dives every time, which can be a little awkward…
That’s why next up on our Scuba Refresher Checklist are a few Diving Breathing Exercises; to put you on the fast lane to improved air efficiency! Let’s Dive in:
Diving Breathing Exercise Explained: The key to getting the most out of your air supply is improving your diaphragm muscle. This muscle stretches across the lower portion of your rib cage and separates your heart and lungs from the abdomen; it is absolutely pivotal to proper air exchange in the lungs.
Most of us are guilty of lazy breathing by only using our chest muscles to expand and contract our chest cavity and thus breath.
However, deploying your diaphragm will allow you to draw air deeper into your lungs, improve oxygen exchange and ultimately improve your air consumption. To achieve this, we need to strengthen the diaphragm and actually start using it effectively when breathing.
Diving Breathing Exercise #1: Lay down on your back with your legs bent. Place one hand on your chest, and the other on your abdomen, allowing you to feel all your muscles engaging while breathing. Now, practice breathing deeply and slowly from your nose, while focusing on engaging your diaphragm as much as possible.
You should feel your stomach rising and falling, while your chest should barely be moving. This takes practice, but keep at it and you will start to feel a difference.
Diving Breathing Exercise #2: Another one of the best Diving Breathing Exercises to improve air consumption is to simply work on your breathing rate:
You’ll notice in the previous exercise that we stressed breathing deeply and slowly. This will require some practice!
Focus on inhaling very slowly, while staying very calm and not elevating your heart rate. When it’s time to exhale, don’t simply breathe out all at once, but rather focus on very slowly exhaling a little at a time.
Diving Breathing Exercises Summary: Altogether, these Diving Breathing Exercises will improve your breathing control, decrease your respirations per minute, and ultimately make your air supply while diving last longer.
All those possible benefits make it sound like a pretty vital one of our scuba diving refresher tips, right?
Listen up. Of all our Scuba Diving Refresher Tips, the Scuba Weight Calculator aka Scuba Buoyancy Calculator, can be a finicky operation; so it requires the most explanation. Best get comfy!
Ready? Great! So: remember your early diving days where the instructor eyed you up and down, twiddled their thumbs, and magically produced a weight value that worked for your Scuba Buoyancy needs?
They were sizing you up, estimating your weight and calculating how many additional scuba weights you’d need to Remain Neutrally Buoyant.
Well, their ability to guesstimate weights and actually be close comes from years of experience in the water.
However, now is as good a time as any for you to start honing your own scuba weight calculator skills!
In essence, you must determine if your tank will be positively or negatively buoyant, and compensate with additional weight.
Given a choice, we recommend getting a steel tank as they tend to remain negatively buoyant whether full or empty. Add all these weights together and you have the ideal additional weight you need to wear for optimal buoyancy!
Remember, the goal is to slowly sink with an empty BCD and full tank at the beginning of your dive (at the surface). At the end, when you’ve lost some weight from using the compressed air, you should be perfectly neutrally buoyant.
We realise that this Scuba Weight Calculator process is a bit of a handful!
As well as this, you will undoubtedly tweak your weights as you continue diving.
If you don’t have the time to iteratively determine your required weight…fear not!
There is a ballpark estimate you can use to get close, and then adjust from there.
Simply carry 10% of your body weight in additional weights. This number will certainly not work for everyone, but it is at least a starting point.
Regardless of which Scuba Buoyancy Calculator method you’re using, you’ll need to complete a buoyancy test once you have your weight picked out.
Don’t worry, it’s very easy! Simply strap on all your gear as if you’re embarking on your dive, deflate your BCD completely, and get into the water. At the surface, you should be slightly negatively buoyant and sink slowly even when inhaling.
Plunging into the depths like a boulder is not the goal! You want to begin your descent nice and slowly; remember that as you go deeper and your gear is compressed, you’ll pick up some speed!
Just two more Diving Tips left on our Scuba Refresher Checklist! Great work. This one’s nice and easy:
Our obsession with scuba abbreviations leads us to yet another Scuba Acronym. Its long-winded name is the PADI 5-point scuba descent acronym, but all you need to remember is SORTED.
Signal your fellow squad member(s) that you’re ready to descend.
Take a look at your surroundings and get your bearings in relation to the shore, boat, or any other landmarks in the area. Ideally, glance at your compass at the same time to help cement your area awareness.
Unless you’re in the mood to swallow some seawater, put your regulator in your mouth and take a couple of breaths.
Take note of the time that you’re beginning your dive. Most dive computers do this anyway, but it is still beneficial for you to think about turnaround times and your total bottom time.
Be sure to equalize the pressure in your ears even before you start descending. Also remember the point that we discussed earlier: equalize early and often during your descent!
Now you’re ready to begin descending, slowly deflate your BCD and let the adventure begin. And there you have the last item on our scuba descent acronym!
This particular scuba acronym is thankfully short and very easy to remember. Simply run it through your mind a few times, put it to good practice in the field and you’ll always be…SORTED!
Now that you have the scuba diving acronym for descent cemented amongst your other scuba diving refresher tips, we’ve almost covered all of the essential elements of our entire scuba refresher checklist!
You’re just about ready to jump back in the saddle – or BCD, in this instance – and get back into the water! But there is one more item our squad members want to cover beforehand. Hint – what do you need to Scuba Dive?
It’s essential that you fully understand every last piece of scuba gear; after all it’s what you’ll need to dive! That’s why we’ve put together this handy Dive Gear Checklist. In addition to operating the gear properly, this will allow you to complete the Scuba Buddy Check that PADI recommends for all divers.
The following pieces of gear are essential items for you to review and include on your dive equipment checklist.
Scuba Regulator – Reduces pressurised breathing oxygen to ambient pressure and delivers it to the diver through a mouth piece.
Divers take two – one for them and a spare for a buddy in case of emergencies!
Two Scuba Regulators, a Dive Gauge and BCD attachment hose together form the Scuba Octopus
BCD – The jacket divers wear to maintain optimum buoyancy, which they can adjust by operating the inflate and deflate buttons.
This makes sure they neither sink to the bottom nor rise to the top of the water!
As well as this, the BCD keeps in place the divers regulator(s), dive gauge and air tank.
And there you have it Diving Squad members! We’ve fully covered our scuba refresher checklist from top to bottom and reintroduced all the points you should review when dipping a toe back into the big blue.
From your scuba weights calculator to your scuba buddy check, all your pre-diving bases should be covered – and then double checked with the standard dive check PADI recommends.
Once in the water, we covered your scuba acronym for descent, diving equalization during the descent, and a few of the best breathing exercises for diving.
Of course, we also reminded you of the most important scuba hand signals for communicating with your fellow squadmates as well as a. complete scuba gear checklist!
Now all you need is the perfect location to rinse off those diving skills with a refreshing plunge into some crystal-clear tropical waters!
