VR3 issues

The software on the Shearwater has always worked very well dating back 2 years ago to the KISS-Shearwater prototypes.

Now Bruce put it in a different housing that is absolutely bomb-proof. Drysuit divers won't feel the size, but wetsuit divers might think that it is big eventhough the overall dimension is supposedly the same size as the VR-3.

Batteries last more than 1 dive

, or more like 1 year based on Bruce's estimate.

You will like the buttons much more than the VR-3. There is no on-screen prompts like the VR-3, but the sequence is laid-out very logical (i.e. similar to "normal" dive computers with one for "select" and the other for "next" etc.).

There is no nice color screen like the VR-3 color (which is one of the best screens on any dive computer I have ever used), but information is easy to read.

Did I mention that the GF deco actually work and match the tables to the exact minute when tested on a square dive profile ?

Now, if I could get one dive computer that has:

same color screen as VR-3
same strap as the VR-3
same battery acceptance as VR-3 (1.5 to 3 volt)
same GF algorithm as Shearwater
same size as Cochran EMC-20H (?) or smaller
same buttons as the Vision handset

then it would be the perfect computer IMHO

Let's add some more features:

dual batteries with proper switchover and indication of which battery in use
wetconnector for upload/download/connection to PPo2 controller
three buttons
not floodable
great customer support
free software upgrades
up-to-date PC package
easy OC bailout gas selection

He he - coming from you thats hysterical

Theres a difference between 'not working' and 'working but not liking how it works'

VR3-VPM is not same as VPM in the same way as Sunto-RGBM isnt same as RGBM or VR3-Buhlmann isnt the same as Buhlmann

See below differences between VR3 buhlmann, VR3 vpm and VPM for 80m for 30min 10/52 setpoint 1.2

ok a i missing something here.

those figures are excellent, however the deco obligations raise some concerns !! just simply adding up the deco minutes gives the following

vr3-0 - 132mins
vr3 vpm - 144mins
v-planner be-0 - 113.42mins
v-planner be+3 - 130mins
cochran - 148mins

in my mind there seems to be a huge difference !! from smallest to longest - there is 34mins difference.

Now you wouldn't get out of the water on purpose knowing you had missed 34mins of stops, so why would anyone dive on the v-planner be-0 tables ??

i dive a pair of vr3s (not vpm) so how do i know they are not either cutting deco short, or making it excessively long.

i guess you pays your money and just trusts the computer !!

I guess you can never know for sure what is enough. So it might be wise to do the longer one. If I plan with v-planner I use +4 conservatism... Or go with the VR bühlmann...

Yeah yeah rub it in

Thing is unless it becomes public knowledge that something has issues how are you supposed to know?

I currently lust after the sheerwater computer. Will I have to buy one my self before any "issues" are aired on the net? Its either that or getting a VPMB VR3 to try and get my bailout running closer to the HH or even my buddies on Visions.

Down side to this is that I have herd loads of negative feed back on the old VR3 yet my two have been perfect apart from dropping one line of the led display and a leaking crappy cover for the Fischer connector.

Go figure

Mark,

Sometimes things are public knowledge without having everything spelled out... It is all on how you read the information.

What you have learned first-hand is already available at least 2 years before...

Hi people. I am new diving rebreather. I have no VR3 computer but I have been thinking about buying one. But now, having read all the posts about this issue, I am not so sure about buying one.
From what i have read, models are models, they try to approach reality, and trying is never 100% accurate. I guess, I would by that computer that I thing has the more reliable algorithm. No my question is, because i am not an expert in all the algorithms that exists, how may i know which one of all is more accurate? The one that reports less decompresion accidents? The one that gives me more decompresion stops? I do not know if I would go for the one that gives me less decompresion stops, but is a choice, when i am thinking about diving OC with very limited gas reserves.
Is there anyone who has suffer from the bents using VR3 for an aggresive dive? is there anyone who has suffer from the bents while using the COCHRAN?
I really want to buy a technical computer, since I own an Aladin Z, but from what i have read it would be safer to stick to my tables and bottom timer.
Thanks.

Willibo,

The VR3 is hands down the most prevelent technical diving computer in the world. Is it perfect? - absolutely not, but there are more dives done daily on it, than the rest of the so called "technical computers" combined. I wouldn't let a little grumbling scare you into not buying it. I have 3. 1 monochrome and 2 color. The jury is still out on the VPM upgrade for me, but I have absolutley no qualms about the Buhlman versions. Just like every computer and model of decompression software out there, adjustments must be made for your personal preferences.

It works for 99% of the people who own them.

Just my $.02

MixAddict,
Which version do you prefer, colour or monochrom? I have heard that colour screen is dificult underwater, i.e. you may not identify everything as in the monochrom.
Do you Prefer VR3 over Cochran? Beside the OC reason, is there another one?

Thanks for your replying,

Willi
