Hello Cedric,
Although I agree with you on many points, I disagree with others..

I also STRONGLY DISLIKE the fact that the handsets go to sleep on you if you don;t touch any buttons even while you are submerged.. The displays should be on at all times when being used.. If you hit the menu buttonto wake it up, it now immediately takes you into change setpoint, You have to remeber to hit the confirm button to wake up the handsets to see whats going on.

I got to build some Megs from the ground up so I appreciate all the work and testing that goes into them..

Hi Joe,

I agree with you about the setpoint control. It's not the perfect one but most of the time, I fly my unit manually so it doesn't bother me.

About the sleeping hanset, I mainly use the HUD and I just have to push on the Confirm buttonto wake the handset up. This feature increases the battery life, so quite a good idea.

By the way, please could you write a small report about your course. I plan to do it so any feedback is more than welcome.

Cheers

If you look at the movie archives you can see him using a hybrid Meg. with the Hammerhead. Pretty nice system, but I like my Shearwater for a variety of reasons some aspects highlighted by Stuart in his Meg. teardown. My particular Shearwater has been flawless.

It's interesting that most of the Meg issues that have been stated are around the electronics... Matching the Meg with the HH certainly does address those issues...

and while at the moment I do not have a Hammer Meg.... Stay tuned.....

Dive Safe...

Mark

Saving battery is good, but nothing beats being able to glance down and immediately see all 3 cells at the same time.. I frequently check my DC, so checking the controller at the same time is a natural..
Although the Hud works rather well, I really dont like counting blinks, that why I dont even use that mode on my HH, I just set it to diaplay alarm status... red, orange and green..

Right now I am a bit over whelmed with projects but I'll try and put a report together..

I would like to hear what has gone wrong too, on both units. People rave about build quality, but what's more important is what goes wrong and what happens when it goes wrong. ...and how well the manufacturer responded.

I agree as well. Have a green blob, Dave.

If we take a poll, I would entertain a guess that majority of the ECCR divers do not fly their unit manually. So the unit's ability to keep SP is quite important, I would think.

Wouldn't it be simple to make this feature optional ?

Let the diver decides if s/he want the handset to be able to go to sleep or not.

My biggest complaint about the Meg is the electronics.. Although I think they are better than something like the prism, I feel they are still very weak.

My biggest complaint is the set point control, I think its aweful... No adaptive control, just fixed injection on/off times that the DIVER must choose what suits him/her best.. Even the Inspiration Classic maintains a much tighter control.. But neither the classic or Meg is depth adaptive,but the Classic is error from SP adaptive..

Hi Joe, the Prism is known for how well it holds SP, better than the other units tested by the USN, including the Inspo. So considering that this is the main purpose of any unit's electronics, what about them could be so bad? Maybe you don't like them because you can't change the electronic SP underwater?
Also, while adaptive O2 injection sounds like a good idea, I can't help but wonder why it's necessary. The Prism does a very good job of holding SP at depth with a 1 second long injection. It takes depth and prior O2 consumption into account and anticipates the coming injection, before it dips. And when, other than a fast ascent(!), would a unit get so far off SP as to require a longer injection rate? Inquiring minds want to know... Thanks, -Andy

One thing I love about the vision, is that it is so easy to dive on, making video work a lot less task loading. It's almost as easy as diving on OC again (during the dive). Talking to one instructor in the red sea, he said he prefers to dive on the Kiss or a vision over the Meg. If Leon sorts out the electronics with APECS 3.0, then the meg will be the best unit out there, but at the moment I belive the Vision is the most compleate package.

I have not dived the Meg so I can't comment about it, but after years of diving the KISS units, I notice that I am starting to get a bit complacent when diving the Vision electronics because (as you said) it is so easy.

By far, I find the Vision electronic to be the best controller package I have ever used (other than the hand strap). Knock on wood, I have not experience any of the issues I have read from other users.

However, I am still interested in trying a Meg someday. May be when more units are out there to create a bigger second-hand Meg market...

Hi James
I am not not totally in accord with what you say:
Inspiration Classic or Vision are two really goos units but,
with the Meg you are free in the anterior part of you body and very hydrodynamic in water.
To work with video and other, I'm forced sometimes to alternate OC and CC and the integrated computer it doesn't help me in this.
Besides I find, that the deco program that is currently found on the Vision is not really the more adjourned among the algorithms and the profiles proposed not really ideal.
This is my opinion shure

All the best

Just curious... Can you not change the setting to OC-bail-out on the computer when going to OC, then back CC mode when back on the loop ?
