Hud for a Classic Inspo

Lord M · 1st November 2006, 22:23

Well, I am new, so I thought I'd ask the question here.

I have a Classic Inspo, with Beanie 4th cell adaptor & VR£. I have been contemplating HUD's. I've read the Shearwater and URI hud info and wondered what everyone's thoughts were. Is there any others out there worth looking at? (3 cell monitoring preferred)

I know Mark Chase had a Uri for sale, but someone beat me to it. So unless someones got one lying around I'll have to buy new.

Used the Sherewater used the URI HUD, if you can afford it get the Uri HUD

Why?

One red one green LED per cell. Solid green no flashing when everything is OK and it just seemed more intuitive when it wasn't OK. I felt I developed an understanding of each cells performance and i could confirm by cell swapping.

Down sides. I have had a few loose LED's in the display head and the cable needs some TLC

The Sherewater HUD is great value and Its good but I found the set point mode flashing light irritating. Others love it so its obviously a marmite issue. However it does the job just fine but I felt i had to put in more effort into noticing flakey cell performance.

At the moment i am diving the tricolor HH Hud with DIVA and it reminds me of the Sherewater. I have to say i just ignore it and only pay attention when it flashes red. I cant get a feel for cell performance and i find my self looking at the hand sets a lot more than i used to.

Beleive it or not i was considering putting the URI HUD on the HH. However in the end I had to sell it to cover my spending on the two HH units

. I may possibly get used to the HH Hud and start to like it more in the future.

You could also use the rEvodream HUD. There is an article about it on Rebreather World.

I like the Shearwater HUD and have no problem with the flashing led's. I found it very fast to spot when a cell is not tracking consistently as well as it should.
I have still to dive it in bright daylight, so I have no idea if the led's are bright enough to see them under these conditions

Here is how to connect it, I would suspect that it is more or less the same for all the other aftermarked HUD's

I have to vote shearwater having just ordered one, the flashing is good - you know its working and it tells you what PPO2 you have not just whether your on SP or not.

Of course I will be posting a review when I have it

This is the standard response abut PP02 HUDS. In my case (but obviously not in others) the flashing became white noise and i just ignored it. In the red sea or shallows of UK I couldent see it at all. If something does go odd I had to stop, look, concentrate and count all the flashes. This just drove me mad.

A minor cell error and it would drive me crazy doing all sorts of erratic flashing throughout the dive. It was too much information. Too distracting. The guys using just hand sets were having a far more relaxing dive. Do you really care if the cell is flicking between 1.24 and 1.3?

My hand set checks will tell me this and what I really want to know is am i dropping below 1.2 or above 1.4. The in line deco will sort out the rest and if i were on back up tables/computer they would be set at 1.2 anyway wouldn't they.

I switched off the PP02 flash setting on the HH and now run it on warning mode.

With the Uri HUD the three solid greens just sat there not interfering with your dive and then the slightest flicker or red flash stood out like a beacon and you acted immediately.

I don't buy into the "if it flashes you know its working" idea. Electrical lights that fail usual go out in my experience. If it stays fixed green its assuming set point so what difference does it make if the assumed set point results in a flash or a solid green?

Fo divers who haven't used a HUD before any HUD will be fantastic. I have not herd of any one taking them off. However i have tried a range of HUDS and have been diving them for a couple of years so its not quite the same for me. I started out with the URI HUD so that may be an influence on my preference but ever since then I find my self thinking, its OK but not as good as the Uri HUD with every one I have dived since.

I have to say bassed on price alone i would have got the Shearwater unit if i was making the choice today and didnt know any better.

There are really two failure modes for a HUD, dead or hung. Dead could either be a single LED or the entire HUD, it this case you're right it's really a matter of its on or it's off. If it's on it must be working. The problem with the hung state it that your LED's will be on and displaying it's last good value. In this case you would see a solid green and have no real way of knowing whether you're on/off setpoint.... until you check your handsets of course

I work in an IT related field and have a distrust of devices that can hang and not inform the user.

rEvodream is a very cost effective way of adding a HUD to your unit.

Also, I suppose it does both - there is a flash as the HUD shows you each cell's reading but you also get an indication of PO2 from which LEDs light. Anything other than green and you get another LED showing higher or lower and by how much, so no counting necessary.

Will fit Beanie's adapter.

Like the sound of the Shearwater but that needs a bit more saving up for.

So you really have to consider the rEVOdream code which is the exact response to your problem.
It is somewhere in the website or a least in my computer, really great thing

I also vote for the revoDream.

The flassing seccuence gives you the PPO2.
In case that the main electronics dead, you have an absolutly independient two sensors system, so you could dive manually without problems.
