Skill 1, Demonstrate Scuba Equipment Assembly
- If your BCD is dry, submerge it in water before assembly
- Hang your BCD onto the air cylinder with the strap at the top of your BCD
- Using the tank strap secure the BCD to the air tank
- Make sure your BCD is facing you and that the “O Ring” face of the tank is also facing you.
- Check the O ring, make sure there is an O ring in place and that it is not damaged.
- Loosen the yoke screw to remove the dust cap from the first stage of your regulator (octopus) assembly.
- Attach the first stage to the cylinder and tighten the yoke screw (if you are using a DIN type valve this will screw into cylinder valve), make sure that the two second stage regulators are on your left. They will be on your right side when you are wearing the assembled BCD and tank
- Ensure the first stage has been secured and is seated correctly then tighten it into place.
- Connect the low-pressure inflator hose to the power inflator on your BCD
- Hold down your regulator purge button and open the cylinder valve slowly by turning it anticlockwise
- Take your finger off the purge button and continue opening the cylinder valve.
- Make sure there are no leaks at the hoses, connections, 1st stage valve and O Ring, both 2nd stage regulators and all air release valves.
- Turn the cylinder valve ¼-1/2 a turn back (clockwise)
- Test the low-pressure inflator
- Test the exhaust valve on the power inflator hose
- Test all other exhaust valves on the BCD and overinflate the BCD to test the over-pressure relief valves
- Check the reading on your pressure gauge
- Breath from both regulators, test the purge buttons and make sure the pressure does not drop when breathing
- If you smell or taste anything strange DO NOT use the cylinder if you suspect the are is contaminated.
- Your scuba unit is now ready, stow it by laying it down tank first or if on a boat by the tank securing device
Skill 2, Pre-dive Safety Check (BWRAF)
- Check the power inflator hose, check it works OK inflate your buddies BCD using the low pressure inflator and by orally inflating it.
- Deflate the BCD by pressing the deflate button on the power inflator hose and by checking all exhaust valves on the BCD
Weights- check your Buddy’s weight system:
- Make sure you know how to your buddies weights system is set up
- Check to see if they are integrated or a standard weight belt and you know how to release them.
- If using a weight belt make sure it is right hand release
Releases: Check and get familiar with your buddies Releases;
- Familiarise yourself with all the buckles and straps on your buddies BCD, including shoulder straps, chest strap, Velcro cummerbund/waistband and waist strap.
- Check the tank strap is secure and the tank is at the correct height, one hands width below the curve of the top of the cylinder.
- Check the Scuba Tanks’ strap. Make sure the tank is secured and located at the right height (the strap should be placed around a fist bellow the tanks markings
- Make sure that your buddy’s air tank valve is open
- Check the pressure, you should have 2500-3000PSI at the start of the dive
- Breath from both second stage regulators, if you smell or taste anything unfamiliar or if you think the air may be contaminated don’t us it. Look at the pressure gauge as you breath, if the pressure drops check that the cylinder valve is fully open, if the cylinder valve is open and the pressure continues to drop when breathing check/change the regulator
- If there’s still needle movement after turning the air on, there might be a problem with the regulator. Replace the regulator and check it again.
- Breath from your buddies Alternate Air Source, secure it in the correct position and make sure it is easily released in case of emergency
- Check that your buddy has his Fins, Scuba Mask and Dive Computer.
- Check that your buddy is streamlined, and everything is attached and secured.
- Check that you brought all accessories required.
Skill 3 – Deep Water Entry
Giant Stride Entry
The giant stride is used when entering the water from a boat, piers, or dock and where the surface of the water is no more than 6 ft from your starting position.
To perform a giant stride entry follow the steps below:
- Stand with your feet at the edge of the boat deck, or platform.
- Place the snorkel or regulator in your mouth.
- Place your right hand over your face so it secures both your mask and snorkel.
- Place left hand over your weight belt buckle. This helps prevent the water impact from opening the buckle on entry.
- Check the area below you for any hazards or other divers in the area.
- While standing straight up and looking straight ahead at the horizon, step forward with either foot.
- You will enter the water with your legs spread wide apart. Bring them together as soon as you enter the water to help propel you towards the surface.
- Display the OK signal as soon as you surface.
Skill 4, Buoyancy Check at The Surface
- Place your first stage regulator in your mouth
- As you breath from your regulator deflate your BCD completely
- Continue to breathe from the regulator
- When ready take a full breath of air and hold it until you remain in one position
- If weighted correctly you will float at eye level, if over weighted you will float below the water level, if under-weighted your eyes will be above the water surface
- Adjust your weights accordingly and repeat until you float at eye level.
- When your weight is set correctly exhale to submerge
Skill 5, Snorkel Regulator Exchange
- Exchange snorkel for regulator repeatedly without lifting face from the water
- Practice correct regulator clearing by expelling air from your lungs or by pressing the purge button
- Do not hold your breath
