The following are examples from a popular 2021 Instruction manual. This is example of documenting what is taught and what not taught. There is difference between opinion, and syllubus. All have is syllubus. Opinion fine in many curcumstances, but still opinion is opinion. Have recived some "Private Messages," and many emails. Many indivuduals have pointed out from their recent courses, that hand signal's not being taught. Or if taught very small amount of time spent on all of them. Everyone agreed that "out of air" or low on air not an issue, <<<<< on surface, or when "instuctor" in front of face submerged. Everyone agree that student never taught what to do, if they have emergency underwater, or very minimal instruction. Emergency and how to "ask" for help underwater never covered. Point being students are NOT taught to ask for help or assistance underwater nor are they given opportunities or instruction on handeling emergincies underwater. From their personal perspective. all this talk is about instructors perspective, no one actually listining to students or getting feedback from students on what is effective way to handel emergencies. It if instructors talk, then Instuctor assumes student heard, when student's do NOT hear. But instuctor's keep speaking anyways.
IMO
"Train divers to minimize stress and anxiety and to avoid panic in
the water. Recognize outward signs of diver anxiety and panic
and stay focused so nothing distracts you from intervening with
a person who is stressed and anxious"
"7. Respond to air depletion by signaling “out of air”
and securing and breathing from an alternate air
source supplied by a buddy. Continue for at least
one minute while swimming, surface and inflate the
BCD orally."
"12. Recognize and demonstrate hand signals."
"Dive 1 Performance Requirements
At the surface:
1. During briefing, recognize the hand signals for “okay,”
“something is wrong,” “ear problem,” “low air,”
“up/end the dive,” “stay with your buddy,” and the
audible (or tactile) and visual signal for “look at me.”
"Exercise 4 — Distressed Diver Underwater
1. Correctly identify and respond to a diver simulating
overexertion underwater.
2. Correctly identify and respond to a panicked diver
making an uncontrolled ascent.
3. Correctly identify and provide air to, via an
alternate air source, a diver simulating an out of air
emergency, and make a controlled air-sharing ascent."
"Exercise 2: 15-minute Tread
Tread water, drown-proof, bob or float using no aids and
wearing only a swimsuit for 15 minutes, with hands (not
arms) out of the water during the last two minutes." (Other popular certifying agencies require 30 Min.)
"Supervision
Do not leave participants unattended, either at the
surface or underwater.
• Position yourself so that you or a certified assistant
can make immediate physical contact with, adjust
buoyancy for, and render assistance to, participants.
• Continually observe participants with only the brief,
periodic interruptions needed to lead the dive and to
provide assistance to individual divers.
• Do not engage in any other activities, such as
taking photographs or video, while supervising
participants."
"14. Communicate using hand signals at the surface and
underwater."
