Suunto vs VR3

[marlas]

could someone explain something for me??

What algorithms do the Vytec DS and the VR3 use? The reason i ask is that having used the Vytec with the deepstops and having run similar dives on the planning mode on the VR3 (dives in the 50 range at least), they comeout with largely similar profiles i.e both incorportate short deeper stops with the vast bulk of the deco done at 6m (or thelast stop)

Despite this, there seems to be a general opinion that the VR3 is by far the optimal compouter for deco diving. Aside from its upgrade capabilities, more gases etc etc. I am not exactly sure why this is.

Anyone??

what software level are you running on the VR3 ??

You'd better hope its now Windoz XP The Vr3 only had two buttons...

Aditionally, search the Image bank in Google for Control Alt Delete. Why do I get naked ladies next to computers???? Weird..

you get similar results becuase both machines run falvours of the same decompression algorithm. Don't believe any nonsense you read adbout suuntos running RGBM, it's not true. Suunto licensed the name "RGBM" but not the algorithm, in a stunning piece of marketing bullshit. The upshot is that both machines run different variations of good old fashioned buhlmann, although the V3 is now also available in a flavour of VPMB if you prefer the more modern bubble models.

Both machines put in versions of deeper stops

The VR3 is definitely more flexible in terms of functionality. More gases, full function in terms of changing parameters whiilst underwater, games, ebooks, etc.

But it's not cheap...

All deco systems do the bulk at 6m (or 3m)?

Can you show me a profile for a 50m air dive for 40min bottom time using 32% and 80% for deco on the Vytec? I had the old Vytec and it was absolutly nothing like the VR3 profile


VR3 60min deco

1 @ 34
1 @ 25
2 @ 18
5 @ 15
8 @ 12
8 @ 9
5 @ 6
25 @ 3

Deco Planner 20/80 52mins deco

1 @ 39
2 @ 21
4 @ 18
5 @ 15
6 @ 12
7 @ 9
27@ 6

Aside from profiles the adavantages with the VR3 are:

TTS: it tells you what yout total time to surface is using all available gas

You cant bend it in a way to stop it working it will just flag the error and carry on.

It will credit you for deco even if you dont ascend to the recomended ceiling. (this is very important)

It handles Trimix & Heleox

You can reprogram it during the dive if you need to bail onto an unplanned gas

Obviously it also upgradable to CCR but that might not be an issue for you.

It will take back gas and more than three additional deco gases
