Let me see if I can turn this back to diver education for a moment.
I read on here all the time where people say that todays training has been "dumbed down" or something to that effect. So here is a question for some of you folks who have been in this business/sport/hobby for many years.
Can anyone specifically give examples of what use to be taught in an Basic OW course that is no longer being taught that without that knowledge, you have put the new diver in some type of jepordy? (He/she is less safe) For example, what has NAUI/PADI or whomever dropped from their course that they taught maybe 20 years ago and no longer include in todays course?
I'm not really talking about how the course material is taught (online vs class at a shop etc.) so much as what is being taught.
Growing up, I remember having fire drills in schools, stickers on the bedroom windows to help firefighters identify the rooms where a child might be, and a family action plan in case of a fire. We didn't have smoke detectors until I was in high school. We had a fire extinguisher located at the top of the basement stairs. The school never caught fire. Our house never caught on fire. None of my friend's or family's homes ever caught on fire. My grandparent's home had an electrical fire after they died when my sister and her husband were having the house renovated. No one was home at the time. A neighbor spotted smoke and called the fire department. They put it out quickly and did more damage making sure they got it all - which was covered by insurance.
Since most people's homes and schools rarely catch fire, is it safe to say we no longer need family action plans, tot saver stickers on kid's windows, or fire drills? After all, smoke detectors and home security systems provide early warning in the event of smoke or fire and should give a family ample time to get out, right? Or, are fire drills, tot rescue stickers, and the practice of family emergency plans still valid?
In diving, equipment has made us safer much like smoke detectors and home security systems, but we never know what might go wrong or where the "fire" will be located. I remember being taught to have a primary way out of the house, a back up way out, and a third way in case I was cut off from my secondary escape in the event of a fire.
PDIC skills usually teach 3 ways of doing something using the same philosophy. For example, 3 ways of regulator clearing: 1) Hum into the regulator to clear it. 2) Push the purge button to clear it. 3) Swish, by using the tongue as a piston to pump water out in case you've exhaled all your air and the purge button is covered by a diver's hand. In case you are out of air: 1) Share air with an additional second stage. 2) If the additional second stage is damaged, filled with debris, or not working switch to buddy-breathing with the donor's primary regulator. 3) If the donor cannot buddy-breathe or the divers lose control of the buddy-breathing situation, then an emergency ascent is warranted.
Of course, skills like tank valve breathing and breathing from the BCD auto/oral inflators have been left out. If a donor with a non-working additional second stage (octo) cannot buddy breathe, it would be easy to use the oral/auto inflators as a third regulator.
For some, this might be overkill. For others, it is a third way out of a fire.
The question is should I tell my students not to dive with divers who lack the skill to buddy-breathe?
I don't know. Would I want my kid, if I had one, to know 3 ways out of a neighbor's house in case of a fire if he were sleeping over at a friend's house? Would I feel comfortable letting him stay with a family who told me that they only know how to escape through the front door, but that I shouldn't worry - they have smoke detectors and a home security system?
Even people living in apartments often have a fire escape outside a window.
This tells me, as a diver, we should have 2 if not 3 ways out of a jam.
With the elimination of a skill such as buddy-breathing, in the event of a problem with an additional second stage, a diver's secondary resort is an emergency ascent which would be like jumping from the roof.
Think about each skill that you learned as a diver. You should be proficient in 2 ways of accomplishing the purpose of any task if not 3 ways.
You never know when you'll need it. It's nice to be prepared when fire does strike so you don't get burned.
