Looking to Buy a Rebreather

[tbone1004]

You need a better HUD. I have zero issue seeing my Fathom HUD, be it full daylight or pressed against the glass of my mask in a silt out. I was in a complete silt out in rocky horror and the only thing I COULD see was my HUD. If you want something jiggly on your wrist, great, but don't make it out to be the most MAJOR safety feature introduced to a CCR.

Fathom not compatible with my Meg and none of the cell splitters are terribly reliable. If you ever dive one with haptics you'll realize how good it really is. The Fathom HUD is very bright, but it's far from the only option for safety improvements.

I've hung out on anchor lines that were fluttering in the current. I would not feel a haptic over that vibrating line. No way would I trust a haptic as my first line of defense. Lights in eyeballs.

To refer back to your earlier comment:



(40/33+1)*0.21=?
(30/33+1)*0.21=?
(30/33+1)*0.32=?
(20/33+1)*0.32=?

Those are “Air/Nitrox in shallow water” PPO2 calculations, no?

You’re in the rebreather forum, advocating that limiting (or lowering) the minimum PO2 alert to trigger haptic feedback in an mCCR monitor when at shallow depths, would be a good idea. Please tell me you don’t run an 0.4 (and that’s ignoring your earlier comment about wanting to be able to run below a 0.4 when shallow, as your first post would indicate) at shallow depths in your mCCR.

You keep claiming that i am advocating something. I simply reporting what Shearwater set as a default warning level.

You are clearly more interested in diminishing others to prove your very insecure sense of superiority.

Grow up and think a little harder (i know it hurts) on this topic before you continue to embarrass yourself.

You seem like a prime candidate for adding to the Ignored user list. Keep it up!

The first line of defense should be looking at your monitor to know your ppo2. Huds and haptics are secondary indicators.

Your logical fallacy is ad hominem

You attacked your opponent's character or personal traits in an attempt to undermine their argument.

A nice feature upgrade would be to have a ppo2 warning for the 0-40ft range where 0.4 would be appropriate, and another for the 41+ range where maybe 0.9 might be a good trigger.

I worry such a sentiment will imbue those lacking any experience on a CCR, such as Marie, into thinking that your “feature upgrade” request, with the notion that a sub 0.4 PPO2 underwater on a rebreather is anything other than farm animal stupid.

You are ignored. Go polish your turd of a personality somewhere else.

If haptic is such a safety improvement, why weren’t instructors and CCR manufacturers clamoring for Shearwater to add it to the Petrel long before now? Didn’t TDI just update CCR full cave standards to mandate a second display? That seems to be more of a priority safety wise.

Before last month, it existed in only three fashions: the Hammerhead DIVA HUD (no longer made), Inspo (still available IIRC), and the Divesoft Freedom handsets. Most new units use Shearwater electronics. There are very few units that can't accomodate two monitors, albeit with the crappiness and unreliably of splitters.

how do you know we/they haven't been?
Shearwater is very hush hush about their developments and while I'm obviously not connected to Shearwater, doing an update to the Petrel was clearly very low on their priority list. It should have been the very bottom though, it worked and it was very small in terms of their growth potential compared to the Peregrine, Perdix, and Teric. They're running like a "real" company now and they have to with new ownership so no one will fault them on it. It's also been fairly low of a priority for the manufacturers because they've had the NERD and blinky HUD's as options. KISS is really the only significant manufacturer that isn't using DiveCAN or their own electronics *yes I am aware of guys like Fathom, Triton, etc. but they're insignificant in terms of size*, and they have always had the Freedom as an option which also brings the benefit of being able to manually vote out cells. I actually firmly believe that a single handset with haptics is MUCH more reliable and safer than using any of the cell splitters to have dual outputs. If you want to do that with a NERD then that's perfectly fine and arguably better than the wrist units since it puts it in your face, but either are still much more reliable than splitters and that makes them safer IMO.

The Teric has had it since that came out a couple years ago. Shearwater also now recommends only lithium energizer batteries, and the haptics wont work with alkaline cells. The motor is very strong and must require a relatively large amount of power. That may have limited the practically before.
