Dive Training – Jan 24th 2009

Update:

Class went very well.   We had lots of students and three of those were refreshing skills.   We had three DivCons in the class, two helped with the open water pool session one.  I had the opportunity to work with the refreshers.   Boy, I will tell you, this is fun.  The three students were pretty much perfect.   I went over all the update skills with them without any issue.     I do want to point one thing out, though this not the first time I have seen this it is very important.   While acending do not put air into your BC!  If you do you are looking trouble.    The purpose of putting air into the BC is to keep you afloat on the surface and trim out your buoyancy while you are below.    Anyway, just wanted to share.   Enjoy the read!!!

It is time again to start reviewing some of the skills I learned while going through the SSI DiveCon course.     This coming up weekend, I will be assisting one of the Adventure Sports SSI instructors with dive class.   From what I understand, we will have several newbies and a few updates.      I will be reviewing the DivCon Scuba Skills update documentation in particular to make sure I do not miss anything.   We as DivCons generally perform the Skills Update solo.  Periodically reviewing the documentation keeps my mind sharp so that both the students and myself benefit from the training update.    I will go ahead and post an update when the class is complete and let everyone know how it went.

Shannon will not be joining me for dive class as she has to work.   We typically work as a team which allows some our classes to be a bit larger.

So if you are in the Kansas City area and with to get some dive training, do visit Adventure Sports.   Depending on the instructor teaching your class, you may be working both Shannon and myself.

-Thanks,

Enjoy Scuba Diving

By Dean Novosat

Scuba diving can be a life-long adventure involving travel to foreign lands, continuing education and interaction with a bunch of like-minded individuals who share a passion for the undersea world and it's exploration. Our planet is 85% covered with water and at this point we know relatively little about our great oceans and seas. Only a small fraction of the Earth's waters have been explored. Diving can be done anywhere there's water including oceans, seas, lakes, ponds, and rivers. And we can technically include swimming pools since this is where most divers learn to obtain their certification. Learning to scuba dive can become the beginning of a lifelong adventure.

Many people dive both as a fun and recreational activity but there are professional scuba divers too. There are the most famous divers, the Navy SEALS. But most cities and towns have water rescue teams that include divers. So if you love diving, you can always make it a career. There are also professional treasure hunters who scour the ocean's bottom for shipwrecks laden with gold! Even though they may use high-tech devices like satellite photos and sonar, a diver is always needed to go to the bottom to recover the bounty.

Since diving can be viewed as an extreme sport, it is always recommended that the rules of diving are learned and followed accordingly while engaging in this adventure sport. You can earn your PADI certification and hundreds of locations. And if you arrive at a tropical resort somewhere and suddenly decide you want to learn to dive, most resorts offer lessons right in their pool. You can get certified quickly and then head right out into the ocean to explore the undersea world.

Many people erroneously assume that since you are underwater, the weather doesn't play a factor on when you can dive. This is not true!

Scuba diving can be limited by weather conditions just like any other activity. Since you usually take a boat to a dive site, winds and rough seas may make this unsafe. And inclement weather can greatly affect the undersea currents making diving unsafe.

Diver Panic

By James Costello

What is the most serious condition a diver can experience underwater?

DCS (bends), narcosis...?

It's probably panic, for the simply reason that once a diver starts to panic he/she looses all rational thought processes. In most cases the irrational thinking renders the diver giving self-help almost impossible. The diver is not able to 'think there way out of a problem'; below is an example:

You are diving a famous wreck in local waters, the depth of the wreck is at 40m and the visibility is around 10m. The pre-dive excitement and anticipation are high as you enter the water, once you and your buddy reach the wreck you are overwhelmed by its size... You both spend the next few minutes swimming around the wreck until suddenly you look around and can't see your buddy. Then your dive computer starts to beep as you run out of bottom time, you realize your some distance from the ascent line; so you make a made swim for it. In your haste to get to the ascent line, you don't see the mass of fishing line and it gets entangled around one of your feet/fins. The more you struggle the more you get entangled, with no one to help, you start to panic. No bottom time, limited air supply (at that depth on a single tank)...

It's easy to say, but not so easy to practice; BUT if you stop for just a few seconds try to calm yourself before you hit the panic stage. You can think about your predicament more logically... Relax and slow your breathing (to conserve your air and reduce CO2 build-up), which will make you feel more relaxed and less stressed. Look down identify the problem, maybe removing your fin will make it easier to untangle! If you have a knife or EMT shear (which are highly recommended), take them out and start cutting.

Even if you exceed your bottom time by a minute or two, your diving computer will still prompt you as to what to do (safety stop, ceiling etc); and obviously in this kind of situation it would be advisable to stop diving for a 24hr period if your no decompression limits are been exceeded.

A simple trip to break the circle of panic in a diver is to get them to perform a very simple task for themselves. This shows them that they are in control, and help clam and reduce the level of panic.
