Shearwater Pursuit versus VR3

Steve-M · 24th July 2008, 14:39

Hi All,

I have just purchased a Shearwater Pursuit to use as a backup decompression computer and oxygen cell monitor for an Evolution. Using the Narked at 90 conversion kit, it has all gone together very smoothly and very tidily. I must say that I am very impressed with the Shearwater Pursuit and the Narked at 90 conversion kit. Good job, guys!

In parallel with this, I have bought one of Jason's Subsea Systems DS-1 wrist display and HUD for a Sport KISS. Another very good product and another satisfied customer.

The DS-1 comes with the option of fitting a VR3 computer as a backup display...but this will only show one cell, not three cells. This made me think, why not connect the Shearwater Pursuit to the DS-1 instead of the VR3? I have decided to do this.

Has anyone carried out a comparison of the Shearwater Pursuit against the VR3 ?

Some things are obvious but quite trivial. You can see a profile of the dive on the display of the VR3... and you can play a simple videogame during the decompression stop ... if you really want to do this. Both allow you to download the dive profile and see it on a PC screen. Are there any significant differences? The method of inputting a decompression safety factor is different ... but will this really matter very much on a real dive?

Surely this thread has already been discussed ... but I could not see it in the archives.

Not being a VR3er, are you saying that when plugged into DS-1, the pursuit shows all 3 cells?

Good topic by the way

.

Both are good computers (had both systems) but in my humble opinion the Pursuit is better mainly because of user interface, the vr3 was a bloody nightmare, but the big plus is that it can monitor 3 cells without another box of electronics. For conservancy the Persuit uses GF, so dial in what you want, and for the VR3 I used 0, as I found that was conservative enough.

I didn't play games on the VR3 as I thought it was a minor miracle that it worked in the first place and didn't want to push my luck too much

I also feared that the buttons would pop off / break as well.

So in my opinion if the Persuit will work with your system then get that.

Decompression using Gradient factors.

Nuff said.

That is correct. Both 8 pin ports on the system can take either:
DS-1
Shearwater Pursuit (3 cells displayed)
VR3 (1 cell displayed)

Redundancy was the main driving factor in the whole design. You can plug in two DS-1's (as several users have), a DS-1 plus a Pursuit (as I and a number of others have), a DS-1 plus a VR3 (most popular option thus far), or even two Pursuits.
At the moment I think the DS-1 + HUD + Pursuit is the ultimate mCCR monitoring package.

Cheers,
Jason.

Wow -- why would one even consider a vr3 for a backup if it only gives you one cell? thats like spending the money on a six pack but only getting 2 beers!

great info

Yeah and with my experiences with the VR3 I'm sure if it had a leg it would kick me in the nuts as well!
The pursuit IMO is the only way to go, just the fact that the Bruce's customer service is second to none! Swayed me....

Its like buying a six pack and finding out its got 10 year old flat american beer in the two cans.

Anyone who would ever consider spending money on a VR3 that could be spent on a Pursuit is a snorkel wearing fool.

It's only funny until you've seen your button slowly dropping into the murk while hanging on deco. The first time it was 'funny', the second time... not funny. Both are somewhere near the U-853 if anyone really needs a spare...
