Vision and VR3 settings

Stewart McMickan · 20th July 2007, 18:15

I have just got a new colour VR3 and i am using it CC on a 1.3 set point same as Vision. but i am finding that the VR3 is not giving me as much bottom time as the vision. is there a setting i can change on either unit in order to have the NST much the same on each unit.

What GF settings are you using on the Vision & what conservatism settings on the VR3 ? Also which deco software is the VR3 running ?
I am running 15/85 GF & 0 conservatism & I find the VR3 keeps me in water longer but that doesn't bother me .I follow the most conservative but in an emergency I can follow the quickest out the water .IIRC somebody told me 10/70 is closest to 0 on the VR3
If you do a search I think there was a thread somewere that gave rough equivalent settings between the Vision & VR3 .

I am using 90/95GF

I run mine the same as Colinicky (see previous post).
Vision GF set to 15/85 and VR3 set to zero conservatism has produced the closest results.
Mind you I'm comparing deco scenarios not no-stop limits.
With these Vision/VR3 settings when I leave the bottom the Vision shows slightly more time-to-surface (TTS) than the VR3 but the VR3 tells me to do deep stops which can add to (or slow counting down of) its TTS.
Usually by the time I reach the shallow stops the Vision and VR3 TTS are within a minute or two of each other.

I run Vision at 15/85, and VR3 (non-colour 2.1 version) at 10% conservatism.
I follow the same approach as the previous replyer: if all is well, I follow the slightly more conservative VR3 (typically no more than a few minutes difference with the Vision), but if sh*t hits the fan, my Vision will be my "quickest way out". Only disadvantage is that if you ignore the deep stops on the VR3 (which are mandatory, and typically deeper than the Vision ceiling), you get the (in)famous "use tables" message - but the VR3 continues working despite this message.

Just FYI: I run the VR3 independant, i.e. no 4th cell. Also colour or B/W version makes no difference: my wife has a colour VR3, and exactly same result as my older B/W version.

Ciao,

Tino.

That's right.
The last thing you want is them giving the same answers.
If everything is going great come out on the most conservative.
If the world is ending, your gas is nearly gone and your kit is breaking come out on the most radical.

I hate the way divers treat their computers as little plastic oracles that know all and tell all. They are just another opinion on which you base YOUR decision on when to ascend. You can always add extra conservatism by just not ascending when the computer clears. ...and don't get me started on some numbers they write on a slate that magically becomes the holy word as soon as they get wet.
