A post in a recent thread in this forum suggested that rec diving has changed in the last 15 years. This made me wonder, and I replied:
I learned to dive 27 years ago (which makes me, I'm afraid, old enough to be the father of most of my students)
Some things really have changed. I'll try not to make a big story about it but here are the top 10
- dive computers. We didn't have them but they're pretty much standard gear now. I still dive without a computer sometimes and not unexpectedly it raises some eyebrows...LOL (noobs)
- dry suits. I think the first trilam drysuits started hitting the market in about 1985. I recall getting one of the first pototype trilam suits from "Fitzgerald" (now Bare) because I was willing to "test" it for them. Back in the day drysuits had "cuff dumps" that needed to be activated manually and many still had inflator hoses attached to the chest so they could be orally inflated. Diving in a dry suit has become much more straight forward and much more common since then.
- BCD's; We actually had BCD's but where I learned normally people in drysuits used the older horse collar thingamabobs and back packs. Until the Hog config hit the main-stream, it was still the most streamlined way to dive.
- Regulators. My first reg was a single hose Aqualung that was manufactured in 1972. It performed pretty well for an unbalanced piston but frankly, today's regs are in every way superior. IIRC my reg had 1 HP and 2 LP ports, which meant that I needed to add a "T" coupling to it in order to attach the drysuit, the reg, AND the inflator. Obviously, I needed an air-2 type inflator because adding two "T" couplings for an octopus would have been a pain
- oh yeah.. the octopus. Everyone has one now.
- Cave diving has become *much* less suicidal than it was in 1984.
- Light "technical" diving has become much more common and much less of a coin-toss than it was in 1984
- We now have DIR which despite all of it's failings is a reasonably adequate statment of best practices. Unfortunately it's given rise to huge "egos" and smack talk that we never used to have either.
- We now have internet, which means that information actually gets diseminated beyond the 10 people you know personally
- People are universally more careful then they used to be. Diving to 40m on your 5th ever dive isn't something that most people do these days and making 60m bounce dives with a single AL80 and no way to plan deco stops has become a bit of a taboo.
- we do safety stops now
- and understand how to make ascents
- buddies are no longer primarily useful for sharing gas money
- and we now have deco chambers available to sport divers
I"m sure there's more but that's more than 10 and I'm sure it's not the whole list either.
