SCUBA Dive Instructions

Save

Scuba diving requires a number of procedures in order to be carried out correctly and safely. In using scuba gear the diver is effectively putting herself on a life support unit, and techniques learned during initial training will be used on almost every dive from then on.

  • Assemble the scuba unit. Attach the BCD (buoyancy control device) to the tank first followed by the regulator set. Make sure that the low pressure inflator hose is connected to the BCD inflator and then turn on the unit. Check the pressure gauge to ensure the tank has been filled. (The pressure gauge reading should be around 200 bar or 3,000 PSI.)

  • Don the equipment making sure that all clips and fastenings are closed correctly, leaving no loose equipment. To check this, perform a buddy check with your dive buddy. First check your buddy and then let him check you.

    Elements of the B.W.R.A.F. check include:

    Buoyancy: Check the BCD functionality by inflating and deflating it using the inflator hose.
    Weights: Establish where the diver is wearing his weights and how to release them.
    Releases: Check where all of the diver's fastenings are and how to release them quickly.
    Air: Perform an air check by breathing off your second stage, and having your buddy breath from the alternate air source at the same time.
    Final: Check all equipment is in place and you are ready to enter the water.

  • Perform a deep water entry appropriate to the environment. This could be a back roll, a giant stride entry or a controlled seated entry. When in the water check all equipment is in place and signal that you are okay.

  • Begin your descent. Perform the five point descent method. Signal to your buddy, that you are ready to descend. Orientate yourself to where the boat is and where you are going to dive. Make sure that your regulator is in your mouth. Check the time for the start of the dive. Elevate your low pressure inflator hose. Make the final descent signal and deflate the BCD to begin your descent.

  • Adjust your buoyancy underwater. Do this by controlling your breathing and using your low pressure inflator on the BCD to add and remove small amounts of air, to keep yourself "weightless" in the water. Complete the dive making depth changes slowly and starting from the deepest point, gradually getting shallower.

  • Make your ascent at the end of the dive. Signal to your buddy you would like to end the dive and ascend. Check the time for the end of the dive. Elevate your low pressure inflator hose so you can adjust buoyancy during the ascent. Look up and listen for hazards, as you slowly fin towards the surface ,using your dive instruments to make sure that you ascend at a rate of no more than 18 meters per minute.

  • Inflate your BCD fully upon reaching the surface. Signal that you are okay and exit the water in a manner appropriate for the environment in which you are diving.

Tips & Warnings

  • Never hold your breath during scuba diving. Always breath to avoid any potential lung over expansion injuries.
  • Swim slowly and keep calm to avoid over exertion and air wastage.
  • Fin kick with straight legs for maximum efficiency.
  • To scuba dive safely it is essential that you obtain the proper training. The entry level Open Water course teaches the introductory skills to be able to dive safely with a buddy. Do not scuba dive unless you have been trained, or are under the supervision of a certified diving professional.
