Help with vPlanner

[Daylonious]

Hey guys - not sure where to post this -

I'm using vPlanner for the first time, and am trying to figure it out. Is there a way to configure it to "combine" deco stops? For example, the output I get is:

Dec to 130ft (2) Air 50ft/min descent.
Level 130ft 22:24 (25) Air 1.01 ppO2, 130ft ead
Asc to 100ft (26) Air -30ft/min ascent.
Asc to 70ft (27) Air -30ft/min ascent.
Asc to 60ft (27) Nitrox 50 -30ft/min ascent.
Stop at 60ft 0:40 (28) Nitrox 50 1.38 ppO2, 26ft ead
Stop at 50ft 1:00 (29) Nitrox 50 1.24 ppO2, 19ft ead
Stop at 40ft 2:00 (31) Nitrox 50 1.09 ppO2, 13ft ead
Stop at 30ft 2:00 (33) Nitrox 50 0.94 ppO2, 7ft ead
Stop at 20ft 4:00 (37) Nitrox 50 0.79 ppO2, 0ft ead
Stop at 10ft 8:00 (45) Nitrox 50 0.65 ppO2, 0ft ead
Surface (45) Nitrox 50 -30ft/min ascent.


Is there a way to configure it to do say, 4 min at 40, and 14 min at 20? rather than doing 1/2 dozen little stops?

Or set it to have 15-20ft be my last stop depth?

I guess the other obvious question to ask is "Is it safe to do this?"

Thanks for helping out!

There is a way to make 20ft your last stop depth, its under "config" at the top center. As far as combining your other stops, I dont think there would be a way to do that, I certainly dont think that would be a great idea either. You can also extend you stop at gas switches BTW.

Um, I think the whole point of the profile is that that's the "best" way to de-compress. Changing the stops kind of defeats the point, right?

What is the problem with doing the stops the way the s/w tells you to? It's a better way to decompress than simply ascending to 20 feet, letting the bubbles grow and then hoping to fix them later.

In fact, in this profile I'd be lookin at switching to the 50% at 70 feet and staying longer at 70 and 60, and take some time out of the 50 foot stop (make it 1 min)

Also would help to take a decompression class so you can better understand the impace of the deco schedule and how you might want to change it.

Learning it from the internet is probably not the best way.

Limeyx, I've taken a deco class and they never went into any of this stuff. I think you expect too much of our training agencies...

Anyway, yes, its just a config parameter (called "stop size"). Persoanlly I like 10' stop increment though as it gives me a smoother and closer to ideal profile (the ideal profile wouldn't have any stops but just a changing ascent rate). And as the stops are shorter than a 20' interval profile, you don't get too bored waiting to go to your next stop.

If you compare 20 and 10' increment profiles for the same bottom time, I bet you the 10' one will get you out of the water faster.

That's what I was looking for... thanks. I'll keep the stops the same and make my last one at 20.

Thanks Loosebits - It gets me out of the water exactly 1 min faster. How do you use the "accelerate deco" option? Is that only when using 100% o2?

And Limeyx - I'm certified deco and adv nitrox as well - the class never covered how to configure and use different deco software which is why I was asking...

I wasn't trying to criticize with my comments (honestly) but if it were me, I'd find someone I trust who knows this stuff rather than asking Joe anyone on the internet.
Maybe you could discuss it with your deco instructor

I'm sure your instructor would be happy to to go over it with you and explain what the different options mean, and the implications of chahging things around.

Either that, or a lot of people have been conditioned to expect too little.

I don't know what the acclerated deco option does but I prefer to hang longer and not get bent. I generally run at +3 conservatisim. Remeber, even if you follow the plan you can still get bent and making the plan as liberal as possible increases the chances of that happening.

I agree with Limeyx, I'd talk to your deco instructor (if he uses v-planner) or Ross Hemmingway (the guy who wrote the thing).
