View Poll Results: Are RDP chart and basic gauge divers the minority, or majority?
minority but the basics are where we learnt the skills to advance and develop us as divers to where we are today . i do at least 5 dives a year like this . just to keep intouch with the cave man diver .
I believe that the majority of divers are using basic instruments. The poll will be flawed because ScubaBoard represents a community of more active and enlightened divers than the population as a whole.
Speaking to your current dives how often were you ending your dives for your NDL? If you were not then the computer was just a trivia collector.

Actually, it is quite likely that one is ending dives due to gas limitations, yet at the same time the computer is a useful tool. The further away the dive is from a perfect square profile to a multiple of 10' max depth, the more likely it is that the computer is extending the dive, even if the diver is ending the dive due to gas limitations.
I have lots of dives using 80 cu ft single tank that always stay within NDL limits, but which have max depth >100' and dive time >1 hour.
Even an airhog will probably be limited by table NDL, but not computer NDL if he does a dive where he dips to 81' for a few minutes, and then spends most of the dive shallower.

I stand corrected, I was thinking in terms of a square profile plan. You are correct in calling me on the fact that he was able to ride his computer and was enjoying computer extended NDL values.
I voted for majority because that's how I dive- I rarely use a computer since I'm either diving shallow (air limits the dive before NDL) or deep (deco diving on tables).
Every once in a while I will use the computer, but it rarely governs my dive plan.
I did my first 30 dives or so with a watch and a depth gauge (and SPG). Occasionally, I still dive that way. Like two weekends ago when I did a cavern dive without even my depth gauge. I forgot it to be honest, but it was a familiar site and I knew the depths.
Don't worry about the fancy stuff. Stick to the basics and have fun.

I don't think I have ever seen an RDP or table outside of a class here, diving most weekends and every holiday I get is spent underwater.
Not rarely seen, never seen! Most dives are on computer or "trust me" basis of the DM/guide.
Not recommending either, just saying I don't agree that most divers are using tables.
