Hud for a Classic Inspo

Padowan · 2nd November 2006, 09:12

I've also just ordered a Shearwater HUD.

Firstly, the price makes it very competitive.
Secondly, after reading about the flash logic, I like the methodology it does make good sense.
Thirdly, I agree with Rich's sentiments about hanging electronics, and an actively flashing HUD will identify this issue.

From speaking to other people who have used Smithers Code flashing HUDs you get very in tune with the flashing and rather than counting the flashes which I expect everyone would do to start with, you develop a sense of monitoring the colour density, or the ratio of flash to not-flash periods. The intensity of the LEDs also increases when more than 0.5 above or below 1.0 so you really start to see an increase in colour when above 1.5 or below 0.5.

Looking forward to getting my hands on it and fitting it (with my Beanie cell adapter...)

I also vote for the revoDream.

Whenever HUDs come up the RevoDream get several mentions... correct me if I'm wrong but its a 2 cell monitor??

I don't see the logic behind this, why isn't it cheaper and a single cell monitor (for all they are worth) or more expensive and a full 3 cell monitor?

To me it seems 2/3rds finished... 1 cell monitors provide sanity check nothing else but they seem to be dying out, full 3 cell monitoring is obviously getting into the Primary HUD market (like Uri or Shearwater) so why not go the whole hog, why stop at two sensors? You can't dive on it, its now only a check like a single cell HUD.

Maybe I misunderstood but to me it seems like a waste of money.

This was my thought on the subject, which is why I did mention 3 cell monitoring.

I already have a single cell monitor with the VR£ as a backup.

If the cells show different readings you can verify the right one with a dill flush.

IMHO two is enough for PO2 display. Set point controll is a different story.

Hi Ben,

On an MCCR you can dive on it, 3 cells are only needed for Voting Logic to work.

Cheers,

Dave Cooper.

dave t · 2nd November 2006, 12:37

Yeah Dave but on a MCCR the votic logic is done by your computer (brain) instead of an ECCR computer!

In my opinion you need three cells wether its manual or electronic the princible is the same, if you only have two cells how do you know which one is telling the truth (please dont say "do a diluent flush"

Hi Dave,

I am not talking about using it as stand alone readout, but as a primary whereby you have a secondary, be it a VR3 or another rEvo.

A short glance from primary to secondary will give you an initial check and then for further clarification a dil flush will suffice.

This is no different than 2 cells wrongly being voted in on ECCR when they are wrong and the third is right.

Of course this is only suitable for MCCR.

Cheers,

Dave.

dave t · 2nd November 2006, 13:13

Ah ok, I was thinking in the primary sense, sorry. but having said that I personally would still want a three cell hud

hello ben, just back from croatia :-)

the first rule is have at least 2 independant systems...

then you can decide how many cells you want to run: 2, 3, 4...

so either using 2 rEvodreams, on each one 1 cell, or you put 2 cells one one rEvodream and one on the other (this is the way the rEvo breather is setup), and you can do overkill by mounting 2 cells on each rEvodream

in the setup you can choose to display one or two cells

concerning the flashes, the filosophy of the rEvodream is that when everything is ok, diving in the optimal zone, you get no flashes at all, just solid green, nothing that distracts you..
when you deviate from optimal zone, jou get extra flashes orange or red, and the more you deviate, the more distracting the flashes become: that is the purpose: to annoy the diver when he is not diving in the correct PPO2 zone
once out of the safe zone, the green dissapears, and you only get orange or red flashes..
conc hanging or dead, we use 2 rEvodreams, 2 huds, you immediately see if one hangs

regards
paul
