Defining specs of my Meg: Help !

Philippe GERIN · 17th May 2005, 15:29

Hi list,
Here is a decription of my standard dives: 4 to 5 dives a week-end in the 30-60m range [dil = air] about 50 to 90mn each. This is 2/3 of the time. Remaing 1/3 of the time
is 2 to 3 dives / week-end in the 60-80 m range [dil = Tx of course]. About twice a year is a week long dive trip to the Med (France).
Questions:
1) Scrubber canister: Would you advise a mini or full size Meg ? I'm not interested in the Extendair option. Cis-lunar seems to be over-kill for my needs. I'm pretty happy with the compact size of my Kiss w/ AL 13's tanks. I'd like to keep this compactness on the Meg.
2) Counter-lungs: only experience I had with over the shoulder CLs is an Inspiration "pool experience": I found them a bit obstuctive [this is one of the reason I chose the Kiss originally]. Would you advise the standard CLs or neoprene? What is the size increment? FYI, I have 4L inhale + 2L exhale on my Kiss. Together with other cavities, I estimate my total loop volume to be close to 8L. That's perfect for me. Need the ADV.
4) Electronics: APECS vs Sheartwater? I read that the Shearwater electronics is a popular option with automatic SP switch & deco. I'll take the HUD for sure. I like the one handset feature vs 2.
I dive with a VR3. How do the electronics deco algo compare? Is it possible to plug the VR3 into the loop? Is it really a plus to do it?
5) finally... Price?
Best

Considering your profile I would go with the standard scrubber, simply because I have no idea how the smaller MiniMeg will perform in cold water at depth. Even a small reduction in absorbant capacity can lead to a large decrease in duration under the right (or is it wrong) circumstances.

2) Counter-lungs: Would you advise the standard CLs or neoprene?

The counterlung materials have been discussed, and for size I would contact ISC directly.

4) Electronics: APECS vs Sheartwater?

Same with the Meg electronics . Which layout you prefer (single handset & deco vs. dual handsets with separate deco) is really a personal preference. The HUD is a must have in my opinion.

Stuart has mounted a cell inside the loop and will be testing it next weekend.
Feedback and pics will likely be here .

These prices are from October 2004.

Pah Stefan do you have to be so comprehensive - not a lot else to say.

One thing I woudl say is that even the full size CAN / Scrubber is still very small - it is certainly no larger than a standard KISS can...

So would definatly say go for the standard size.

As far as deco models goes the VR3 is totally different to the Meg and you can not get a similiar profile at all. However - when you upgrade your VR3 to VPM B like algo that kevin is working on you shoudl be able to tweak the GF to get a similiar profile (I have not actually tried this).

Oooops. Sorry Stuart. Wanted to get something done here today.

That article stuff has me

which gets me

Further to your scrubber size question. The standard size scrubber seems to be the one to go for.
But apparently if you dont want the option of going to the CIS scrubber, Leon does the Movie meg size case, with this the can is shorter than the standard can but it takes the standard meg scrubber.

Thanks for your comprehensive responses.
FYI, I've posted this same e-mail/question list yesterday to the Meg Hatchery yesterday but no response yet. I guess the team is busy assembling Megs.
Stuart, if I'm not mistaken you have the Shearwater electronics, which leaves a bulkhead connector available for VR3/HS Explo. That would not be true with the Apecs set as the 2nd bulkhead is used for the 2nd handset so one would need to drill a 3rd to use an VR3/HS Explo.
Is this correct?

***schford*** · 17th May 2005, 19:40

Thats right Phillipe - I use the second bulk head connector which is 1/4 inch NPT to integrate the HS Explorer 4th Cell....If you went with the Apecs you would need to drill a hole - but if it was me I would just get Leon to drill an extra hole when you order it if thats what you do go for...

I am trying it out tomorrow!

Are you flogging your KISS then Phillipe??

Stuart,

I'm surprised. I dive a VR3 as my backup computer and find the profiles are very close. They both clear within minutes.

The GF algorithm will never give stops as deep as the microbubble stops on the VR3, but GF will then give a couple of intermediate stops that the VR3 doesn't, then they will pretty much sync up.

I used to play around with the GF, but I usually just leave it on the 30/85 default now. It gives me deeper stops than pure Buhlmann and I think that's the right thing to do.

Let me know how the HSE compares and the conservatism setting.

As another potential scrubber option, does anyone know if there's a plan to offer a radial scrubber in mini-meg size? That would make for a hell of a tech-travel unit,

Thanks,
Robert
