In-depth research for proposal (level 2-hand signals)

Level 2
Hand signals are major part of scuba diving as the scuba divers unable to communicate verbally while diving underwater, therefore the hand signals are created and taught to allow the divers to give instructions and communicate.

It is part of essential element of scuba diving as all the instructor will be teaching the learning scuba divers to recognize the hand signals and the correct response to each hand signals. Below are some of the common hand signals for scuba diving.


There is a video teaching similar hand signals in an underwater situation, it is a good reference for the accurate hand signals as it is taught in a real life footage.


In-depth research for proposal (level 1-equipment)

Level 1
Level 1 mainly focus on the proper setup for scuba diving equipment and the essential items for each scuba divers, therefore here is the research of equipment and the accurate method to wear the scuba diving gear.
Here is the list of basic scuba diving gear which will be include within level 1:
  • Mask
  • Snorkel
  • Booties/ Wet socks
  • Fins
  • Wet suit/ Dry suit
  • Buoyancy Control Devices (BCD)/ Buoyancy Compensator (BC)
  • Regulator/Octopus
  • Accessories

Mask:
Dive mask creates a pocket of air in front of your eyes and nose so you can see clearly underwater and equalize the pressure on your ears and sinuses as you go deeper.

Snorkel:
Snorkels are breathing tubes that allow you to inhale and exhale when you're swimming facedown on the water's surface.

Booties/ Wet socks:
Booties offer warmth and better foot protection and are much safer than going barefoot, they come in a variety of styles but they should be comfortable to wear which are comparable to a good pair of running shoes.

Fins:
Scuba fins translate your kicks into smooth, efficient movement through a medium that's 800 times denser than air. Full-foot fins go on your bare feet; open-heel or adjustable fins require that you wear booties for a proper fit.

Wet suit/ Dry suit:
Even warm water conducts heat away from your body 20 times faster than air. Wetsuits provide insulation against this cooling effect. Common options include 3mm-thick suits in both full and shorty (bare arms and legs) styles for warm water; full-length 5mm or 7mm fullsuits with a hood and gloves for cold water.

Buoyancy Control Device (BCD)/Buoyancy Compensator (BC):
Buoyancy Compensator help you control your position in the water column. By adding air to an internal bladder, you rise toward the surface; by venting air from it, you sink toward the bottom.

Regulator/Octopus:
Regulator lets you breathe underwater. It connects to your tank, delivering air to your mouth when you inhale. An octopus is a backup regulator. It usually has a longer hose and a bright yellow body so it's easy to find and can be used by others in an emergency.

Accessories:
Dive lights:
Specially sealed flashlights that bring out colors on the reef, allow you to peer inside reef crevices and even dive at night.

A dive knife:
A tool, not a weapon. Used to cut lines, rope and monofilament.

Dive case:
Hard-shell cases protect valuable gear in transit and seal shut to keep their contents dry in wet environments.
