Review of the Evolution by MAD

"What about sealing the battery compartment? Gas proof at 1ata or still (more or less) ambient pressure?"

I understand that all new units with Vision Electronics now have a sealed battery compartment. There is now an O ring in the lid of the battery compartment to make it a sealed unit. This is a change made in the last month or so and wasn't on the original Vision units. I have seen an Inspiration with this improvement a few weeks ago which had come straight to a student from the factory.

Thanks, the last unit I had a chance to take a closer look at was last October at DEMA.

Firstly... Dave, thanks for the feedback from Martin. Not suprised they have a fix already for the Buzzer... actually pretty much what I came up with.

I always find Martin very responsive... exellent service


Thanks for the feedback... appreciated... hopefully be following up soon with some underwater shots... once I don't look like a total gimp diving the bugger



Not sure of anything till I've actually tried it myself... but to quote the manual - "The second control module provides total redundancy in the life support functions and both modules will continue to operate without the wrist mounted display"

However you raise a good point regarding the effect of saltwater on the cable ends... One for the AP team, I'll ask.

Or alternatively I'll let you know why I've tried it myself... hopefully never...

I reality I suppose severing a cable is much less likely than a display flood... the same question still applies though.


Absolutely correct, both are options, costing £115 inc vat each. The basic unit comes with bottom timer software. The upgrades are via a simple key file upload.


On my unit, still at ambient and unsealed... but I hear that the new units coming out of the factory have an O-ring seal. (I've not verified this yet)... that's the problem with being an early adopter...


Ah well.. there goes a fortune in Cristo-lube... bugger...

Mark,

My understanding is that the handset is at ambient pressure and if the case is compromised or the cable cut, then flooding and a compromise of the electronics may occur.

I believe when they say:

"The second control module provides total redundancy in the life support functions and both modules will continue to operate without the wrist mounted display"

that they mean if it fails electronically.

I may be wrong but that is what we were told on the Instructors update.

Cheers,

Dave Cooper.

If you block off the inhale hose from the top of the scrubber and then blow down the exhale hose, the head should pop straight off no problems.

Don't forget to undo the latches though!!

Cheers

Thanks Dave...

Tried it... nearly gave myself a ruptured hernia in the process...

I've either got a particularly stiff one (oooh eeerrr ) or I ain't got enough puff... (Suspect it may be the former... OK I know I'm asking for trouble with this post)

The other thing I've tried is leaving the O2 MP hose connected and letting the solenoid inject and it pops off on the first injection cycle... not sure this is a good method though.

Cheers

Mark

p.s. You'll be getting the surgeons bill for the hernia operation...

Thanks for a grat article Mark, if I was a mature enough poster I'd give you my first green!

I have ordered my velcro buzzer straps from Nicky, and will get a sealed battery compartment when I get the units service for the first time.

I haven't been in the water for the last couple of weeks and am feeling the lack!

Nice write up. My Vision electronics for my Inspiration will be in my hands in about 10 days, gettign the trimix/C02 temp stik version.

I have to agree with the sentiment that it seems odd to have the HUD on the left side of the DSV AND teh handset being made for the left wrist.

Being a typical middle aged geezer, as it seems we're the only ones with the bank accounts who can spring for this stuff, I need gauge readers for the closeup small stuff.

The last thing I want is for the HUD to be in the way of my left eye trying to read through a gauge reader to my left wrist......

What's up with that?

Another question, I could have sworn that the original Evo HUD had a vibrating componant in it, and my first instantaneous reaction was, didn't Jeurgensen Marine patent that aka the DIVA?

Lastly, I have a Howell OC/DSV that came with a stripped female thread in the bottom 2nd stage body that holds the Dacor Viper purge cover....I don't know if he has spare bodies or if I need to put a stainless helicoil or brass knurled or splined boss in it.....but...I did notice that there is a metal one way spring impingement washer that slides down once and that is what holds the 2nd stage to the DSV square body.....seems like it would be next to impossible to remove to change the o-ring in between the´two bodies.....

decoweenie

Kevin is not going to spend lots of $$$ to apply and enforce an international patent on that...

caveseeker7

Well, what did you expect from people driving on the left side of the road?
