It completely blows my mind that you guys would pay more than $1000 (sometimes as much as $2000!!) for something that is totally useless and not needed.
Learn how deco works and you won't need to rely on a computer and can spend that money on things you really DO need like more regs or stages or a trip to your favorite destination
What are you afraid of? You need a machine on your arm to tell you it's ok to get out of the water??
I was going to blast you for making the above offensive statements without intoducing the way you do deco, but i had to run out, and when i got back you had submitted the post below. Good for you.
everybody is entitled to their oppinion, it doesn't supprise me that yours is offensive, and demeaning considering your training.
you ar eright if computers were totaly useless and not needed then it would be a huge waste of money..you are correct in the fact that they are not needed at all, however they are usefull by making your dive more efficiant, felxible, and deco more reliable.
I do need..no ....like to have...yes.....a machine on that says it is safer for me to get out of the water, even providing a graph showing compartment loading, which is a benificial part of that deco process.
If you don't mind i would like to address some of your comments, not in order to convince you to change the way you do things, but to educate you in the way others might do it, so you will consider that prior to barking comments down from your high horse. since this thread is on the VR3 i will keep my comments associated to that
In all seriousness: No, I don't have a lot of Trimix experience but I do have a lot of deco experience and I haven't used a computer yet... and neither do the guys/gals who do have a lot of trimix experience that I dive with (including a trimix instructor).
As i stated before...anybody pushing the limits of decompression theories and procedures and using trimix will find to there advantage the use of the VR3, i described why in posts above.
as you stated you do not have much experience so you probably don't need a computer at all until you get more experience.
I think simpler is better and using a computer might seem simpler on the surface but it's not.... you still have to have tables in case the computer dies anyway right? So why even use it in the first place???[
Why use a dive computer on the surface, i carry two computers, with my dive buddies two computers as back up to my back up. who needs tables...
that is the most accurate point you have made so far
If the argument is against square profiles aren't most "trimix" dives pretty square? If not one can use an avg depth with tables too... I do that all the time in the caves. I know most technical wrecks are a square profile....[
once again you are displaying your lack of experience and the lack of experience of those you tell you what to think over a beer after their dive.
any table dive will be a square dive as far as planning goes, that is why computers offer such an advantage over tables. you can use average depth for planning deco. but you loose flexability and accuracy it is the good old George rule of thumb method.
with a VR3 depth and time are completly flexible, you can do saw tooth dives at any depth for any time, and take advantage of the offgassing [or i should say, less on gassing] at the shallower portions of the saw. it is calculated every couple of seconds.
say at 300 - 400 feet every minute will add exponesualy to your deco commitment. with the VR3 you monitor your deco commitment and dive were you want and for how long.
I'm not trying to hammer on the people who use computers I just don't understand it
another true statement, I couldn't have said it better myself
that I just don't see any benefit and for technical diving I just think they are useless.
As you gain more experience and expand your thinking and circle of divers you encounter, the benifits might become clearer
If one studies decompression theory and looks at all the
information out there and really gets a good feel for how it works it's easy
this is very true, see we think the same on many of your statements
Like I said it is interesting to read and good backup for your original statements that you have posted your methods below
You are basicly a table diver, table generated by a comnputer on the surface. nothing wrong with that, i do like how you indicate that you you don't really follow the tables you make anyways, you add this and take away that. this is a good display of not understanding decompression or how to generate proper tables.
maybe you should look at a different deco planner that works for you instead of guessing...oh i forgot you are only aloud to use that one..to bad..well keep guessing and hopefull it all works out for you.
What I do: Print out a set of tables with Decoplanner's "Table's" feature. I print out tables for all the standard mixes I'll be using both with and without deco gas and the range I'll be using them at. I cut them into strips that will fit in my wetnotes and then laminate them and put them in my wetnotes.
Also I'll say now that I don't follow the tables decoplanner puts out exactly. I add deep stops and take some time away from the 20ft stop and do a very slow ascent along with some other minor adjustments.
Once one does the same dive a couple of times this way one won't even need to look at the tables anymore
This is the advantage of not using or relying on a computer and using standard mixes. One gains a better feel for how things work and saves a lot of cashola in the process.
