What deco software?

[Ari]

Yes, I know this was discussed before but what is your favorite Deco Software?

I downloaded GAP, which looks and works very nice and is free. What is YOUR favorite?

Ari :)

Im using the abbyss dive planner 2.17
works fine aldough there is a newer version with RDBMS

Currently, I am using DPlan (GUE) on a Handspring Prism. I like it a lot. For the majority of the dives I do (and probably will ever do) it is great! It is easy to use (especially on a boat) and displays a table that I copy onto my wrist slate. It does not compute travel gasses, but if I really want that, I use DecoPlanner (GUE).

I stick with GAP, used Migplan before that. For the trip I take Decoweenie for those special "oops, we're going here instead" occasions.

I have posted this before but can not get an answer from anyone
Is anyone using Voyager???

I am trying the trial of the Voyager program and have a question on repetitive Dives

I think I am doing it correct for a repetitive dive in that I am entering the first dive and then saving it. I then plan the second dive ,enter the surface interval and then click on the browse button and add the saved file from the first dive. It then shows in red as a repetitive dive.

Assuming that the above is correct how do i do a third dive
Do I just plan the third dive and add the saved file from Dive #2(which is already repetitive) and enter the surface interval between Dive 2 and 3 or do I have to enter both Dive 1 and 2

Thanks Doug

I use Voyager and Pro Planner.

they both have advantages and disadvantages, but i use them together and it works out

anybody hear of people getting bent using V planner, I everybody I know who has had signs of DCS have been using V Planner

[MikeFerrara]

From what I gather reading the V-planner site, the ones getting bent are using nominal conservatism and maybe doing some things wrong. If you haven't yet check out the site (in yahoo groups).

I am currently using Dplan. I also have gap, V-planner and Voyager. Voyager is a great piece of software but it doesn't use deep stops. I prabably like V-planner the best but carrying a pal pilot seemed to meke more sense than a lap top.

Doug Mathieson, At lunch I'll take a look at yoyager or bring the book back to work with me. I don't remember the exact key strokes but I don't remember it being hard either. But...I read the book before messing with it. If you are using the free trial version I realize that you don't have the book.

I use 4 packages, Deco Planner (PC), V-Planner (PC), D-Plan (Palm), and Decoweenie (Palm). Each has advantages but I think the most versatile is Decoweenie as it has selectable algorythm.

Since most of my buddies are GUE trained we usually end up diving Deco Planner or D-Plan.

As far as getting out of the water fastest, generally V-Planner (VPM) will do it. I've done a few fairly aggressive dives with it and haven't had any problems.

I've never tried Voyager or Abyss. I think my VR3 uses a version of ProPlanner though (it's my backup). I don't like GAP as its interface is tricky for me.

V-Planner has treated me very well for a couple years now. I use it to get an idea of what to do, then add in my own conservative factors into my plan. It's easy to use, it's profiles "look right", and it's cheap. Even on air dives, I come out feeling good. I recommend it.

I have been using v-planner with a conservatism set to +2.

I haven't had any problems and feel great after a dive.. This type of model requires close attention to ascent rates and run times.. A slower ascent is not necessarily better.. Don't add in extra deep stops.. If don't like the output manually add in a few way points and let it calculate the rest.... If I use V-planner for OC I ensure I stay at least 3 minutes at the gas switch point to maximize the effect of high PO2.

[WreckWriter]

I set conservatism to either nominal or +1, depending on how strenuous I expect the dive to be. I also set the 70' stop to 3 minutes minimum for gas switch.

If using a GF model program I use 10-90

Is anybody out there running Jplan? It seems to be very similar to Dplan.

[Lost Yooper]

All of my standard dive profiles were cut using +2 conservation with 5mins minimum at gas changes (normally 70' using 50%). I use a 30FPM max ascent rate from depth, and a 10FPM max final ascent rate from 20' to the surface. V-Planner starts it's deep stops at about the right depth every time.

Safety factors that I put in are that I never stay at the max depth for the entire time, and I always hang longer at the 20', 15', 10', and 5' stops than is required. It's a recipe that works very well for me.

What do you do for the five minutes durring this gas change.
it seems that your deco stop at a gas changes are probably one minute, or if there is no deco stop then why the five minutes.

[Lost Yooper]

I guess I phrased that kinda strangely. If V-Planner tells me that deep stops start at 70'+ or so, I'll stop at 70' with 50% for five minutes so I can start offgassing at a deeper depth. I prefer offgassing as soon as possible which is why I opt for 50% rather than 02 most of the time. Switching to 50% at 70' for only a minute or two isn't going to do much in the way of offgassing, IMO.

Mike

[AquaTec]

that makes more since. a deco stop is different than a gas switch
even though you may be doing a gas switch at a deco stop.

and i agree the higher the PO2 the better for off gassing.

I use 36% to get off my bottom gas faster though.

On most dives my gas switch point is 70' (50/50 mix), the stop by default is usually 1 minute. I know this, so I usually manually add in a 3 minute waypoint at 70 feet this maximizes the off gassing.. of course this only applies to OC.

Even if its not a mandatory stop, switching to 50/50 will acclerate ofgassing.. If I carry a travel gas its usually a something like 32/25 trimix and I'll switch at 130 then go onto 50/50 @70. I don't like comming off a very hight helium mix right onto a mix with no helium if I can avoid it.. also in this case, without the helium in the mix the profile created by v-planner is very aggressive and gets you out of the water very fast, the helium adds just a few minutes to the dive and I have felt great after the dives..

This is an advantage to a rb you can gradually reduce your helium/nitrogen content without 1 big change(until you decide to have one).. on my RB I will frequent dump my loop at 70 ft and us my 50/50 bailout as a diluent.. This will drop my He content, but within a few minutes I'll have some He back in the loop.. @20 feet I run my RB as an O2 rebreather flushing the loop every 5 minutes or so to get the offgassed inert gasses out of the loop.. (at the earliest stages of a deco it takes about 5 minutes before the PO2 drops from 1.6 to around 1.3)

[MikeFerrara]

V-planner lets you configure it for a minimum stop time for gas switch stops. I has two ranges stops below 100 ft and stops 100 ft or above.

I usually use a 40% mix. It still gets me off my B/M at 100', then I switch to an 80% at 30'.


I've been using V-planner, GAP, and Pro Planner. Although I use V-Planner the most often.

I just finished cutting my profile for tomorrow's dive to the British Freedom in 200' using V-planner with +2 conservatism.
