pengwe:
I'm going to take the DIR-F class in about 6 weeks, or else in 10. What kinds of things can I do to prepare so that I will get the most out of the class?
I don't have any of the gear, but the shop said they could provide it. I'm thinking it might be a good idea to at least try a dive with BP/W before the course. I normally dive with jacket BC, short hoses, average PADI OW set-up. I have access to a back-inflate BC - would that be similar to BP/W?
Any other suggestions, for anything?
Oh boy, does this sound familiar. I took GUE DIR F two weekends ago and, ahem, um, to understate it, didnt fair so well. Like you, the BP/W - DIR gear configuration was new and that contributed to my demise; although, it certainly wasnt the sole reason for my discord.
First, and this is firsthand experience typing here, get ALL your gear ASAP, again ASAP. Secondly, get in at least 15-20 hours underwater time practicing basic skills.
What are the basic skills you ask? Oh boy, we are alike. You MUST, that is MUST practice buoyancy and trim. Without the ability to be stable in the water column, you simply will not be able to do the other skills.
IF you think you have your buoyancy and trim skills down (you wont but if you 'think' you do) go back and practice buoyancy and trim again. I cannot emphasize enough how important it is to master that one skill.
Again, if you 'think' you have buoyancy and trim down pat, then try doing some multitasking. While maintaining your horizontal pose of stability, try removing and replacing your mask without going up or down more than a couple of feet.
Ah heck, I could go on, but the main thing is, get used to your gear, practice buoyancy and trim (have I said that before?). Get used to the new rig.
Lastly, just before class, get some rest because the course is 3 intense demanding days requiring full concentration.
Have fun, this will be a great experience.
