Congrats on completing course!
I too took the course. One night (3-4 hours) of lecture. One FULL day at quarry. We made 3 or 4 dives? We were never alone, in that we performed many skills. Many equip. removals/replacements. Switching from primary to alt. air sources during practice problems.
The most meaningful drills were probably the Swimming emergency ascent from about 35' (I guess I did it in OW course from 20" BUT was a LONG time ago!
Also confidence building was the entanglement simulation where instructor actually tie- wrap tied my regualtor to a padeye on a 30' submerged metal platform. switch to alt air source, remove BC/Tank, cut loose entanglement, and redon BC/Tank. Granted we knew it was coming but was a little unnerving, just the thought of it, but was no big deal afterwards!
A GREAT, Confidence building course!
I have no strong desire to dive SOLO every dive BUT believe the courses objective of making you self-sufficient, naturally makes one a better buddy!
I have taken to pretty much solo diving when using a scooter as a scooterless buddy is a real DRAG! (sometimes literally!)
Oh yeah, we kept our ALT Air Supply ON all the time!!!
I did it before, during and after the course!
Leaving it off, makes as much sense as leaving your Spare Tire home in your garage!
