Info Scubapro Announces the availability of SP's newest high end technical dive computer with full GF support, G2 Tek, in the EMEA market

[Wibble]

It was mentioned in the Luna thread (I think) that the computer will increase GF up to 100/100 and recompute when stops are missed, so I think the lockout would occur when missing stops at 100/100.

This would imply that it's somewhat "intermittent" in doing a lockout for most people (using, say, 50/80 and who are doing moderate deco dives, say less than an hour's deco).

tl;dr I guess my only question is - Will the Perdix give you useful dive functionality if you surface after having missed a mandatory deco stop. Will you be able to safely dive, using that computer as a dive computer, and with it knowing your correct tissue loading, within 24 hours?

ALL computers still know your correct tissue loading, whether they lock you out or not. The computation of tissue loading is independent of computing desirable stops to decompress. Even the ones that lock out still correctly indicate residual tissue loading after the lockout is over ( and know the correct value during lockout). 24 hours is not long enough eliminate the excess inert gas from significant dives.

@jborg is correct that the algorithm for determining a correct deco assumes you followed the algorithm in previous dives. But the truth is that many (most?) dives aren't like the dives the model was based on (military divers doing square dive profiles in a highly controlled manner).

Shearwater position: "Here is what the model says for you dive history, use the info as you wish"

Lockout company position: "We don't want to be responsible given your dive history, no info for you"

Thus exceeding a stop by 1m/3ft should still mean you're within the 100/100 limits.

I think SOS may be based on 100/100, but haven't confirmed that. It will auto-increment your GF if you exceed a stop by 1.5 m.

EDIT: they don't define mandatory stop. It seems to me that having auto-incremented the GF, that stop may not be mandatory (more relevant to the first stop or two). GF is incremented by 5/10. No idea if it does it more than once.

EDIT2: on reading it again, it increments once and only if the deepest stop was missed. The dichotomy between your GFs (possibly increased) and 100/100 as it relates to SOS is still not clear. I would now guess it applies to the final GF (possibly 5/10 higher than your setting).

What dive computer companies out there would lock you out if you miss your deco stop and what companies that allow you to continue to dive like SW does? Is SW the only company that allows you to continue to dive or are there others?

Garmin has a lockout by default, but lets you turn it off. You have to say yes to a safety warning/liability window to turn it off.

I believe that Ratio is the same as Garmin but I can't remember for certain. Any others?

@scubadada should know the answer for Oceanic.

I guess I missed that the depth sensor is calibrated down to 130 meters, so having a depth "rating" of twice that seems odd to advertise.​

150m

Thanks.

That isn't "significantly" deeper. My Ratio iX3M Tech + goes to 300mt, that's "significant"

According to Shearwater, Perdix can be used down to 260 meters even though depth sensor will capable to operate down to 300 meters.

Suunto locks you out for 48h.

The Liquivision X1 and Xeo behaved like the Shearwaters when they were in production. The X1 was the first dive computer with the computing power to run VPM and later Buhlmann GF, as far as I recall.
