VR2 or VR3

kkcheo · 7th January 2006, 11:19

Hello all.

Can I please have your views on whether there are any advantages of the VR3 over VR2 if:

1. I have no intention of diving trimix
2. I have no intention of diving more than 4 gas mixes.
3. I will integrate either with an O2 sensor to monitor PPO2 in the breathing loop.

Thanks and have a great day!

Ali case over plastic

Pricing?

The VR2 is now normoxic trimix upgradeable down to 20% Oxygen and upto 40% Helium.

I guess the biggest thing is the price.

To be honest I've never seen a VR2 but do own 2 VR3s.

I don't think you are missing anything here; if you're certain about your points the VR3 doesn't offer you much extra that you'll use.

The only thing I'm not sure about is screen size; they look like they're the same....

Otherwise, Bean's point about price is spot on.

Machined metal case ($$$) vs. moulded plastics case.
Unless you drag you gear across sumps and such the VR2 should suit you fine.

With the qualifiers you'vs set the VR2 would be the way to go. And save you some MONEY.

Yep - assuming you will NEVER dive Trimix there's no reason to pop for the VR3. But - if you're wrong you're going to eat that decision......

Re sale on VR3s is good if you change your mind. If you shop around you can get some very good deals on VR3s. I think now the VR2 offers Normoxic it is a better computer. I wouldn't bother with the Nitrox only version because on a CCR its cheep to dive trimix below 30m so why not dive it and be safe.

Hypoxic trimix, normoxic seems to be available.
There's a .doc on DeltaP's website that I can't read, but it's about the new option.

Anyone have an idea of price and best place to buy a VR2 in the US? Same application - Dolphin SCR. Looking for P02 readout and real-time P02 based deco. No trimix, and if I upgrade RBs to CCR at some point, I will get a different brand of computer (don't care for the VR3 much).

Thanks,

Cam

I am diving the Draeger Dolphin SCR and purchased a new VR2 from http://www.divertec.net/ (Ireland EUR 630.- incl. VAT and shipping to Austria) and the ppO2 sensor/ p-connector from http://www.tecme.de/ (Germany EUR 190.- incl. VAT). For OC-diving I will buy the new HP-sensor from Delta P. Yes, the sensor is ready for sale

. But, you have to return the VR to Delta P for calibration.
And as Beanie mentioned above the VR2 has a new option for normoxic Trimix (SCR and CCR, min. 20% O2, max. 40% He) which is activated by factory reprogramming.
