ARE THEY WORTH IT :?: :?: THE COST THAT IS :!: OR ARE THEY JUST LOOK I'VE GOT VR3
LET US NO WHAT YOU THINK

Convenient and user-friendly
User-changeable AA battery either 1.6V alkaline or 3.6V lithium

Easy-to-open battery cap with purpose-built key

External Switches mean the computers are fully programmable underwater

Variable light settings

Right / left wrist mountable,

Multi Gas Programmable
You can install up to 10 pre-set gases in the VR3’s gas list; air, oxygen or any nitrox, trimix or heliox mixture

The great thing with the VR computers is that no matter which gases are in the gas list, if you ever start a dive and realise on the way down that you have forgotten to set a gas you can always do this underwater and then carry on with your dive, making the appropriate deco adjustments.

Upgradeable
VR3s grow with you as your diving career progresses. Start off with the base Air and Nitrox model and if you eventually get into rebreather diving you do not need a new dive computer, you just upgrade your VR3. If you have a VR3 it will even grow with you when you get into trimix diving!

Unique Analyser function
With the optional analyzer mode enabled and cable fitted these are the only dive computers capable of operating also as an oxygen analyzer. Place the sensor on the end of the cable into the gas stream, measure the oxygen reading and set that into your gaslist. Very easy to use and saves you buying a separate analyzer.

Rebreather Interfaces
With the optional rebreather mode enabled and the cable fitted the VR3 are able to link up with both closed and semi-closed rebreathers to provide real time PO2 decompression monitoring and independent oxygen monitoring.

Integrated High Pressure Link
Optional high pressure link cable connected and the appropriate software enabled, you can monitor your air or gas supply, measure your breathing rate and see at a glance how much time you have remaining at depth before you reach your reserve pressure.


Reliable decompression algorithm.
Proplanner was one of the first desk top decompression software programmes and it forms the basis for the decompression algorithm in the VR3. It is based on the Buhlmann ZHL 16 algorithm and, in line with current thinking in decompression science, incorporates 2 minute deep stops on the ascent. These are designed to reduce the formation of microbubbles, which are thought to contribute to decompression illness.

So in short the computer will get you out if the water NOT bent.... This means that if you plan a dive and go over bottom time, deco gas loss etc the VR3 will give you the best deco profile to get you out the water. This is the big thing you can change gas lists etc underwater and have a uptodate deco plan, Is the VR3 worht the money...YES just ask any proper tec diver who understands what they are doing and they will saythe same.

i've got a VR2 and am currently getting used to it (when i remember to wear it) so i also use a suunto as well.
and guess what? ..... yep, i've bent my VR2 a couple of times 'cos i followed the suunto :o
bought on a whim last year but really a vytec would be more user-friendly for me as the VR2 only has 4 interchangeable gas switches: 21%, 32%, 80% and 100%, so it's a bit useless for a 50% switch. however the vytec doesn't do trimix but then again, i think my trimix days are now over as are my PPO2-monitoring days :(
nice toy to look at underwater and a good brain-teaser for me to fathom out what it's trying to tell me (when i remember to wear it) :?

The suunto's run a harsh deco profile to get you out the water quicker also they dont allow for deep stops.
:shock:

yep, quite correct. both a bit different in their approach to fizzing off. my suunto doesn't have the "deep stop" function either as it's an old model just to compound the issue!
i'll wear the VR2 on sat for yet another "which-computor-do-i-follow-dive" :)
all good fun!

Here's something a little bit interesting, about the VR3. It's neither positive or negative, it just see things from another point of view.

Quote:
Farewell to the VR3
The time to sell the VR3 has arrived. I always said I would keep it until DIR gave me a tool to enable me to dive without it, and Tech1 gave me those tools. To be honest, once you have learned all the shortcuts for calculating CNS, Minimum gas, and specifically Ratio Deco, and once you have plugged the numbers generated by ratio deco through a few pc programs to satisfy yourself it's sound, then the arguments for using computers do become a little weak.

That's not to say the VR3 is not a great tool. It has served me well for a couple of hundred dives, and without Ratio Deco, there is no way I would be selling it on. It has always worked flawlessly, and if truth be told, got me out of a few tricky spots, and I could never criticise the unit itself as it is a great piece of kit.

However, the simple truth is that the real strengths of the VR3 are somewhat undone by the DIR approach. The ability to program multiple gases, even whilst underwater, to cater for whatever mix you are diving becomes somewhat irrelevent if you dive using the same standard gas mixtures everytime. The facility for deep microbubble stops is not necessary if we start our deep stops at 80% of the average ATAS. Hell, there's even a fast calculation to work that out. The "time to surface" calculation that I loved with the VR3 is unecessary becuase at any point throughout the dive I can look at the dive time and know exactly how long it is to the surface anyway. If I choose to pad that out to make it more conservative, well there's no difference between padding out the VR3 and padding out Ratio deco, neither are going to do you any harm by making them more conservative.

What I never understood about Deco on the fly was that you only need to know your bottom time and the average depth, and away you go. There is no complicated calcuoations to perform in the water, and once you know how it all works it is a pretty appealing methodology, as there are three people in the water any one of whom is a complete backup for the deco, all of whom are checking to ensure nothing daft is being done. As long as you follow those protocols it's a great system.

So, the VR3 has gone on ebay. The sale was accelerated in the end by a need for some urgent cash after spending a ludicrous amount of money on Tech1, but it was definitely on the way out. There was nothing wrong with the VR3, I would never stand and critice one, or the owner of one, becuase they are a great piece of kit. The simple truth is that I simply cannot see a need for it anymore.


I found it here by the way. http://teamfoxturd.blogspot.com/2006/11 ... o-vr3.html
