Surely your not suggesting that after four open water dives your students are so well trained they would never do anything dumb?
This is exactly what I'm suggesting... as would any top notch Instructor.
I have yet to see my students do anything dumb... nor the students of my other Instructors... nor for that matter the students of any of the quality Instructors from other dive shops in our general area.
I have seen plenty of piss poor trained students doing dumb things.. then when we point out that what they're doing is 1. dangerous, 2. illegal or 3.plain incorrect... I hear a very common response... something like "I didn't know," or "my Instructor never told/taught me about that."
In fact, I will unequivocally state on the record I've seen more piss poor Scuba Instructors, Tech Divers and Advanced Divers doing more dumb things than I can count... but have never seen a newbie do anything dumb on their own.
I have seen new divers doing dumb things they were taught by dumb Instructors, dumb dive masters and dumb techie and advanced diver know-it-alls.
Now just remember - I'm not calling everyone dumb. The majority of Instructors, DM's, Techies and advanced divers are damn good divers... but there are exceptions... and it is unfortunate that new divers have no way of knowing the difference.
How many examples would you like me to give regarding what I'm talking about?
How about the newbie diver with his brand new camera on his very first dive losing it in the ocean... Why? because neither his Open Water Instructor nor Photography Instructor ever taught him what a coil lanyard or retractor was... and that these could be used to attach the camera to your BCD... so that even if you dropped it, it would still be attached to you...
How about the newbie diver I saw struggling in the quarry to keep his head above water because he was wearing almost 40lbs of lead. Why you might ask? He told me his Instructor (who was nowhere around and didn't know he was struggling on the surface) told him that was how much weight he needed. I assisted him in removing 14lbs and he was able to descend. I can only envision the poor guy wearing 40lbs of weight on his first ocean dive because his moron Instructor told him that was what he needed.
Shall we continue...
