A buoyancy test is supposed to be conducted. My experience though with multiple instructors is that the test is kinda subjective and based on the instructors own training. My test is much different than the one I was taught in OW. Takes a lot more time and is more precise. That also goes for the Intro, Discover, etc. sessions. I have seen them conducted with weight integrated BC's that are loaded with 14-18 lbs., depending on size, and the student has no idea of how it is supposed to be done. This, by the way, was in a pool with the participants - let's make it clear these are not students- in swim suits.
Based on testimony the test that was done was put a weight belt on with 30 lbs. of lead, take them into the water roughly shoulder deep, and have them try to kneel down to see if they had enough lead to sink. Then they went up and got their scuba units. Then they got back in the water and went through some skills and were led on a tour to an approximate depth of 35 - 40 feet. There they played with bowling balls and looked around a boat that was sunk there. When they started to get low on air they began their ascent and that's when everything went to hell.
What I have just seen in the last 24 hours is quite disturbing. Regardless of what errors and standards the instructor broke, did not break, what shortcuts may or may not have been taken, and other information such as the improper medical; my take on it is this.
The incident that occurred would not have if standards had not allowed it to be set up this way. The location, the participants, the conditions, equipment, and ratios all played a part in this tragedy. My own feelings on this are that several things have to change in order to prevent this from happening again. Now we can't prevent people from lying on medicals. We can't prevent instructors using bad judgment 100% of the time. Stuff happens and we all have seen it one way or another. We can't even guarantee the gear will not fail or have a problem. Again, stuff happens.
What we can do is this.
1. Reduce ratios. This was recently brought up again in an RSTC meeting. There was resistance. Conscientious instructors who already realize the limits that us having only two hands to deal with UNTRAINED participants know what we need to do. We need to press our agencies to make it a standard and an RSTC guideline.
2. More clearly define confined water conditions and not leave it up to the judgment of what could be an inexperienced or highly experienced but cowboy instructor. Minimum vis (ie swimming pool vis and not one that's been neglected for a year), non silty bottoms, no possible places for entanglement or entrapment, temperatures that don't require putting a child or adult in a freaking five mil farmer john, and restricted or no access to depths greater than 15 feet or some other number that is less than 1/2 an atmosphere. My buddy in OW got taken on a 90 ft dive when she did a discover in Hawaii. She said discover, I suspect resort course but still. 90 ft? WTF?
3. Fill out the same paperwork for an intro as for a full class.
4. Intro's from shore only. No boat dives.
5. This one will never get any traction but it is my policy- pool only. No pool? Then you need to do a full course.
6. Only instructors conduct them and DM's and AI's assist. This will piss off some DM's and AI's who may have more experience than many puppy mill instructors but hey, my own feeling.
I am going to push for SEI/PDIC to support a change in ratios if nothing else. SDI/TDI is already on board with it. I know my other desires will not come to fruition but I think they are reasonable given that, again, these are not students. They are participants in an experience.
