Design faults on the CCR I dive:

Case in point about Manufacturer's response to issues..... RE: Hammerhead

Handset material issue refined over time. New Delrin Handsets, while not perfect, have fewer issues than the older ones.

Rebooting program resulting in O2 Spike was eliminated on the new handsets as well as with a free firmware upgrade on the Al handsets.

Loss of Deco info is addressed on the new handsets by having Deco on the secondary handset, as an option.

Not sure what you mean by isolating the Primary if it fails....

Point is Kevin has been very responsive to known issues on his handsets, continually improving them over time. Are they perfect yet? No. But some on the list would like he and other manufacturers to react to every issue immediately and correct issues that crop up as soon as they are found. Somethings can be dealt with like that but most require major capitol infusions, require major testing programs and just aren't practical in a quantity limited market.

That being said:

Displays can be hard to read in certain situations. I'd like to see a better display, say similar to the LiquidVision X-1.

More accurate time to surface times.

Longer battery life.

Adjustable last stop depth would be helpful.... 10' stop is too shallow for rough seas.

Common issue with all breathers:

Cells are not reliable enough. Seems to be way too many issues with this technology.

Accurate way to measure Scrubber life.


O2ptima specific:

More rugged frame, foot & backplate. It shouldn't be necessary to redesign or strengthen the original design like so many of us have done.

BOV's should be standard on this and every other unit.

Sturdier, maybe longer, hoses.... I don't like the way the short hoses connected to he canister can be over stretched.... Also a PITA to get the bottom hoses over one's head when donning the unit.

Classic Inspo:

Backlighting inevitably fails eventually without any means of repair other than a new controller module.

I've got the feeling that this thread will go nowhere if we only identify issues.

What about the following structure:

Issue: .....
Affected model/type:
Date/Period:
Impact/Risk:
Fix in same model:
Fix in later model:

I could start out by telling you you should not have to learn these skills because you shouldn't need them but I don't. I just ask you and everyone else to not take up a defensive position. Armed with nothing but Murphy's law ("If there's more than one possible outcome of a job or task, and one of those outcomes will result in disaster or an undesirable consequence, then somebody will do it that way.") I would invite everyone to take this as a guideline for deeming something a design flaw.

This warrants a thread by itself I guess. Can we please try and do our assigned homework before we start to do the things we like more?

Hi,


I'm not being defensive but informative that this has been stated by APD and should be considered as routine to be a SIMPLE step that should be done in order to avoid the descripted problem. Once again, this is the diver's responsibility to do things according to standards and manufacturers specifications other than not doing so and considering a potential problem.


Best Regards. Wael

People,

Mark started this thread by stating problems he found. Consider it "in his opinion" if you must and a few have followed suit.
This thread had real value if we;

1) Dont dilute the content by defending unit. Let the reader decide.
2) Stick to the format PCDiver suggested.
3) Only post problems you have personally encountered and try not to hypothesise with "potential" problems.

You may not agree with the findings of the individual, but for a change, hold your tongue and let this be content-rich.

This could be interesting or fall flat coz of the lemmings, arm chair experts and internet divers.

Excellent idea for a thread

On the Classic KISS - you can dil flush without breathing the gas, but it's not as easy as on other units, so I would perhaps change it to "hard to..."

You need to be careful when changing batteries in the displays as it's easy to pinch an o-ring.

On the rEvo I have niggles not problems;

1) with stages on, it's hard to find a place to put the dreams so you can get at them easily
2) the HUD is a bit wide and the outside one is not instantly obvious (mind you I have poor peripheral vision in my right eye and it could be me)
3) again on the dreams, it would be nice to have a loop of some sort so I could put a boltsnap on to clip it off somewhere.


That's it, yep, I love it!!! Can't wait for the electronics.

I'd agree with those.

Yes, Excellent thread. I suggested this on the complacency thread but got no takers.

Meg :

Solenoid pipe gets lose and leaks. Easy to tighten, probably caused by using it as a partial handle when removing lid

Handsets can dim when hot (30deg C)

Potential bypass through cells - I have not seen this but do check them each time.

Buckles on bottom of lungs can come undone. fix by replacing with p-clips.

Angle of o2 hose to solenoid causes strain on quick disconnect.
