Your not seriously the chap who wrote the article are you? I cant beleive for a second that LT who dives a CCR and plans dives to 100m+ cant program a VR3?? Yet she can maintain plan and run a YBOD.
If you arethe chap who wrote the artical then what exactly did you find dificult? I am no genius but I managed to suss out how to use it on my own in one evening. Having set it up in the comfort of my own home, I jumped in the water and it worked first time straight out of the box.
Lets see how to set a VR3
Press both buttons for on
Press left button to go to set gas list
Pres and hold left button to modify gas list
Pres and hold both buttons to select gas and use left button to reduce P02 and right button to increase P02
Quick press both buttons to move to another gas or alter PP02 MOD, Gas on or off, He content etc.
When concluded press both buttons and hold to save gas to gas list and tick gas with which you want to start the dive.
Errrrrr that’s it. What’s the big problem.?
To be sure you set it right pres and hold the right button for menu. Scroll down to gas list tic gas list and it will show all gas active and the MOD set for each gas.
In use during the dive when the deco mix PP02 depth is reached the computer flashes. Push and hold the left button and the gas list appears with the next gas at the top of the list.
Push the right button to confirm gas switch and continue the dive.
Gosh that was hard. About as hard as the Vytec multi gas computer.
In my immediate dive group there are many VR3’s in use and we have no problems to report on the Version 2.1 model. Earlier versions did have problems with the screen blanking during the dive but the 2.1 appears stable so far.
The bit that really annoyed me in the report was the comment that people buy the VR3 to dive the equipment not the dive. And this from a CCR diver
?
madness. The VR3 is a tool that frees up the diver to enjoy the dive and removes the constant worry of following a strict multi level profile. End of story. If it didn’t do that in spades I would just use a depth and bottom timer and run tables.
God forbid you are connected with Divermag. I issue a challenge. Give me any newly qualified Trimix diver or an old hand I don’t care and I will teach him how to set up and use a VR3 to do a Trimix dive with two deco gas and back gas in 1 hour.
