Is this a Dangerous Dive Profile?

[Jez]

i don't think it was dangerous it was very shallow and you weren't yo-yoing any depths that would really get you in trouble(my opinion anyway). like the others said i would change the sampling rate.

Hi Jarret....In my opinion no this isn't. You might want to try changing the sample rate of your computer. It looks like your computer is sampling every 30 seconds. this makes your profile look more choppy than it really is.

What sort of spin doctoring is that? The computer did not generate the excursions. A lower sampling rate will render it useless for reviewing things like ascent rates.

To make the chart have increasing depth in a downward direction, right-click the numbers along the vertical axis, choose "Format Axis...", go to the "Scale" tab, and check the "Values in reverse order" checkbox. You can alse change the maximum, minimum, etc.

Thanks for the input to this point. This was the second dive of the day. The first dive was about 45 minutes with a max depth of 31 feet. What are pros/cons of increasing the sampling rate?

Thanks, I updated the file:

Were you diving the Cessna at Travis Lake?

A lower sampling rate will allow you to store more dives on your computer. The default will usually accomodate any vacation you can dream of and then some so there is no real value in lowering the setting. IMO more data is always better than less in something like this. You can filter data but you cannot recreate it.

Sampling rate does not modify your real time display.

That was a modest first dive I wouldn't be concerned.

The nitrogen loading on the two dives is minimal, so I don't think it was "dangerous". But after a dive like that, I wouldn't be on speaking terms with my ears for a week

Nothing really wrong with your profile.

Your depth was very shallow, nitrogen load negligible, your yo-yoing at this scale was minimal (probably had much to do with your hands moving up or down), the ascent seems to be slow enough to make it safe.

And I agree with TSandM - your ears might have suffered from this dive, but if you had no problems equalizing, you're completely safe.

No this was at Clear Springs Scuba Park (www.clearspringsscubapark.com) in Terrell, Texas. The water level is like 10 feet down at the moment, so everything is a bit shallower than normal.

I guess I am lucky with my ears. I had a lot of ear problems early as a child, and between swim team and just normal swimming I learned how to equalize my ears early on. So since I started diving last year, my ears have been a non issue.
