You guys are killing me! I can almost hear Doris Day singing "Gonna Take a Sentimental Journey"!
Actually in this case, Doris Day would be singing "Que Sera, Sera".
Here are some facts:
- Understanding Deco theory is not dependent on learning tables.
- PDCs (Personal Dive Computers) are not derived from tables. Both are derived from algorithms.
- Instructors should be teaching students to use the equipment they will be diving with. For most divers this is a PDC and not tables.
- PDCs don't get narced.
- PDCs provide an accurate record of your dives and safety stops.
- PDCs represent N2 buildup with an easy to understand (intuitive) bar graph rather than confusing "letter groups".
- PDCs don't forget when you submerged or when you surfaced.
- PDCs don't forget to reset the witness mark on your depth gauge.
- PDCs sound an alarm when you exceed your NDL, MOD or ascent rate.
- Learning PDCs can be less intimidating to a novice diver.
I don't teach tables to my OW students unless they specifically ask me to. No one has asked so far.
Very poignant.
