Dive Computer or Underwater Camera???

[EricJ]

When I first began taking UW pictures, I noticed right away that I'd become a much worse dive buddy, and I also seemed to be less aware of my overall surroundings. :11:

I now know that getting that great shot isn't worth becoming separated from your buddy or group and that the camera can be a huge distraction while diving if you're not careful. (BTW, I am once again a great buddy...even when I take my camera along.)

I heard an instructor recommend that you have quite a bit of experience diving before you start taking pictures. I, personally, think that's good advice.

Just another point to think about.

Man, I can't wait for the thread sequel:

Computer vs Camera Part 2 : This time it's personal!

LOL!

You don't believe in redundancy? I believe in calculating my profile both in my brain and tracking it with the computer. Redundant.

If either one goes haywire or has a lapse of attention the discrepancy between what my brain and the computer says tells me there's a problem.

Similarly, I'm surprised at how many people, including you, will turn off the deco calculations of a Suunto when doing NDL or mild deco dives. Are you so easily confused that displaying the calculated NDL time confuses you?

My buddies brain is my redundant piece of gear.

The answer to turning off the computer functions is because the calculations the dive computer gives me are useless to me. Run the profiles I posted earlier on your dive computer's simulator and see what happens. I would bend most dive computers on a repetitive no-deco dive and pretty much all of them, even multi-gas capable ones, on a deco dive. Even if I was diving within the limits of these computers, I don't consider what they are actually telling me about the NDLs or deco limits relevant information.

FreeDiver...

I have to agree w/ you on this one. The sequel:

Computer vs Camera Part 2 : This time it's personal!

is going to be a definite hit. Better than the ""Spare Air Series""...

I think when a diver is new that this is when they should not use a computer and become proficient at diving without one.

Once you are really good at not using one, you can make the decision whether or not you want one. I don't think you ever really need one.

I don't consider it life support equipment and have really never been able to justify buying one. There are other things that I'd rather spend the money on.

Go for the camera.

Just my opinion.

ok, so where do you get your NDL's from?

NDL does not really exist ~ NDL is a construct.

Every dive is a decompression dive.

Gas in... ... ... gas out.

Gas in... ... gas out.

Gas in... gas out.

Gas in gas out.

Get camera.

Take pics.

Illustrating that you can't understand what you don't know and you don't know what you can't conceive.

It has nothing to do with NDL. NDL does not exist... neither in the singular nor in the plural. NDL is a construct.

I ignore the construct and deal with reality. Every dive is a deco dive.

Gas in... gas out. Gas in... gas out.

Get the camera.

Thanks for joining us this week on "In Touch With Your Mantra" where we answered the burning question "The NDL: Does it really exist?" Hope you'll tune in next week when we attempt to answer "Could my camera strobe really be the AntiChrist"? Until then...........

Please educate me. You said that you developed your personal tables from Decoplanner. Decoplanner is a straight Buhlmann model, with calculations very similar to the ZHL16-based Uwatec computers, and very close to the DSAT-based Oceanic hockey puck computers (unless you add extra conservatism to Decoplanner with gradient factors).

Are you saying that when you surface, these sort of computers will show you with omitted decompression obligation?

Are you saying that your dives routinely would "bend" Decoplanner?

Or is it merely that you have decided that the Suunto RGBM model is too conservative?

Learn more about the models before you try to argue this. Dive computers use 16C, most people using the table generation software choose to use 16B. And, while they may start with the a very similar buhlman base models, the Uwatec computers do have some conservatism built into them. In general, all computers add extra conservatism for repetitive dives.

Yes, the dive computers would show omitted decompression.
