How DO you fit the VR3 strap? i cant find any pictures. I've had to guess...

I have just checked the no stop limits on the VR3 and a Suunto Vyper and the VR3 seems to be the more conservative. Both computers set without any additional conservatism.

Does this sound right ? I had thought, possibly mistakenly, that the Suunto's were one of the most conservative computers.

Any enlightenment gratefully received!!!!!

Using what gas and what deco gas?

VR3's dont like air (neither do I) and they hate decoing out on air.

In reel time diving you will find the VR3 wil credit you deco on the ascent and the Vytec will not. You will find that the Vytec will give a deco comitment at the bottom that will match or be slightly less than the VR3 but the comitment will INCREASE on your ascent unless you do exactly what the vytec wants.

The VR3 will start to clear. By the 6m stop you wil have a lot less on the VR3 than on the Vytec.

Here is an example:


Min 24 into an air dive on the Moldavia prepairing to leave the bottom



Min 31 (7mins later) my deco has increased to 46mins???




I did a dive on Elphenstone reef and racked up somthing like 30mins of deco. 50mins later after spending 30 at 10m and 25 at 6 I had 30mns deco?? Because i hadent stayed above 6m it wouldent deduct ANY deco. I had to bend it that day

Thanks Mark. The comparison was in relation to an air dive looking at the no deco limits (assuming no existing nitrogen loading).

The VR3 manual suggests that the i/o port remains covered when not in use but all that comes with the VR3 is a plastic cover which it would appear could be easily knocked off. Is there a more substantial blank that can be put in or am I worrying unduly ...

(Thanks again for all of the replies in relation to these VR3 queries)

I don't see how the cover could be "easily knocked off" mine is quite a tight fit and not at all easy to remove.

Hi Guys

Got a question related to using the VR3 CC mode with External O2 sensor fitted.

I want a good method of tracking & recording my PPO2 levels over a number of dives. Has anyone used the Prolog software to do this? I'm interested in any comments to see if it's worth my while paying for the upgrade.

Thanks Again

Andy

Has anyone used the

Thanks Iani. Perhaps I am worrying about issues that don't exist but would you say its watertight or does it not need to be watertight, just tight enoughto exclude sand etc ?

Mine has been watertight so far, if you do get water in there I believe you are supposed to rinse it with fresh water then dry it off.
