Crossover Training

richie

i treid that several times but even when the opv was full open i would not dump the gass quick enough to not effect bouyancy , unless i was pinned to the bottom or holding on to something , is mine not working right? i am wieghted correctly with the unit so i can not compinsate for the extra gass in the loop needed to activate opv buy dummping extra gas from say drysuit/wing??????

Actually, Tom and I were talking about this the other day... we've both had an experience where we certified a student who could show us all the skills just fine. They show up some time later for a follow on course and you find yourself asking 'Is this the person I certified? Was I delusional?'... and suddenly instead of teaching the material/skills you had expected, you find yourself doing 'remediation'....

The problem with setting a price for instruction on the front end is the enourmous variation between individuals... I remember an experience a few years ago where four guys approached me about 'learning to dive'.... they were some kind of special forces military... I felt ashamed to take their money... I just had to show or tell them something once and they completely 'got it' we ripped through the material so fast I kept thinking they were ringers just on a lark or something.... then there is the guy that took me all morning to teach him how to do a dil flush...

These issues still apply to someone crossing over... I can not make the assumption they know the material the c-card says they should.... and that's not necessarily the fault of their previous instructor....

If I could only say.... Learn to dive on a CCR just 10 cents per minute!

Not really...

The Insp divers are spoiled from having the electronic doing the work on sensor calibration, but majority of the rest of the units, it is all manual work.

However, it shouldn't take more than a few minutes of explanation. You could do either method:

1. Flush loop with O2 (same skill as O2-flush in any MOD-1 course)
2. Use an injector to simulate what the Insp electronic is doing when calibrating - form an O2 "bubble" around the sensors.

And you honest think all that's worth $600 ?

Don't get me wrong, I am a CCR instructor as well, and would love to spend your money. But I do have to sleep at night too...

All fair points, and I understand exactly what you are saying.

However... those examples are not what a cross-over course should encompass. Is it ?

Thats the kind of attitude that will get my business. And if he discovers that I'm a retard, then I'm sure the course will adapt accordingly and he will suggest soem skill development. But thats coz of the person delivering the material, not a syllabus.



I am a retard by the way.

I think it is exactly the issue. If I'm certifying them as a crossover then they have to be at the same point as a new student upon completion. Their previous instructor and their background is irrelevant in the process of showing me pre, in water and post dive skills. I'm certifying them and they need to show they are up to muster.

Is this a perfect system? Hell no, I'm human after all. I too have had repeat students and have wondered 'why did I ever certify this person'. I have also helped friends out. Should I have done either? Probably not.

Why have I said this? Well I'm just trying to say that we have to make decisions based on the events happening in front of us. There isn't going to be a rule that works and the Agencies know this.

I was trained quite differently on the inspo than the meg. The strategies and skills were quite different and I feel the skills taught to me by Leon are much better suited to the unit. Sure I could survive with the skill set my inspo instructor taught me but the megs skills were hammered into my brain during training to a point where I don't have to think about the situation,just react.
My inspiration instuctor didn't have a DSV so open loop breathing was not taught. Leon does not support SCR mode bailout so we did that differently. Calibration differences were mentioned as was assembly. I sure there are plenty of subtle but basic differences in application.

That's not specific to any unit skill set, and up to the instructor teaching idealogy. If Leon was teaching an Insp course, I am sure he would do the same (as in his MK-15 courses).

Huh ? You lost me.

... to your standard.

For example, students don't pass my MOD-1 course unless they they could do them in (almost) perfect buoyancy and mid-water. But some instructors will accept completing it once kneeling on sandy bottom (as mentioned).

So if the student doing a cross-over with me from the aforementioned instructor, they will have to do as you mentioned. And not the other way around.

Really?

Does he not teach SCR at all, or just teach it in a special way?
