OK... so I might sound a little snarky or superior when answering this, but I really don't mean it that way. Please read it as intended with a pleasant tone:
NavigationCounting kicks for 100 feet - Yea, OK, nice to know I kick 25 times for 100 feet. So?
Compass out-and-back, and square - In poor visibility or at night, this might be helpful. But, I found this shockingly rudimentary. I was a boy scout and am pilot and engineer, so maybe my skills are above average. I could have done this without training, half asleep, and missing one eye. In fact, skills that I would have thought useful to help compensate for drift were not even discussed.
Deep
Wow, look at this crushed water bottle - Yea, so.
Hey, look his red shorts are not red! - Yea, so.
Boat
Giant Stride with rope loose in hand - Yes, I'd never done this before, but mastered it on the 1st try.
Look up, there's the boat, don't hit it - Done this before and knew not to surface under the boat.
Fins off and ladder exit - Done this many times before, and learned nothing new.
Night
Giant Stride with flashlight on and in hand - I always fumble with this a little, since I am also securing other gear and mask/reg during the entry.
Underwater signals in the dark - easy to forget sometimes, but obvious once you've done it.
Don't blind me bro - always happens anyway
Drift
Here, hold this rope - I'd never done this before, but it was simple.
Deploy DSMB - I asked to do this, since I had never done it before. It would not have happened otherwise. I wish I could do it several more times with an instructor's help.
