What Changes Would You Make to A Meg?

Draeger FFM, bracket to mount my VR3 on the handset, prototype billet aluminum hose clamps, prototype 7.5 lb radial canister, experimental injection algorithm... (OK, i didnt design all that stuff, but I do get to play with it)

dude why are you bogarting!! all of the new inner space toys , i thought we were bro's?you are probably holding out on the apecs 3... when i painted your bike I encripted a chip that will make the paint all peal off !!! so don,t make me use it! inconceivable! i think not!

Net mage: thank you for clarifying.

Gilles: I think I understand what you are saying but say you only have 1 point calibration and check that they are linear... what do you do if they are not (linear)?? Isn't this where the 2 point calibration comes in, to correct for non-linearity? Obviously this is only "correcting" in the range between 0.21-1.0 (or whatever calibration range) and could still be "off" outside that range. I don't see how a 1 pt calibration at high PPO2 would be better since wouldn't your second point still be 0,0? This still wouldn't help you above 1.0 (or your max PPO2). Or are you saying since you will typically be operating at higher PPO2's that you would rather calibrate and be close in this range then at low PPO2?

Or is my understanding completely off? Sorry for the off topic rambling.

Actually, you touch upon a truth, albeit somewhat impractical. Yes, if the cell is becoming non-linear, the 2 point cal provides a small mitigation. The problem is that few undertand the need to check that the PO2=1 mV is 4.8x the PO2=Air mV. This is the only way you can check (on the bench, short of doing an water spike) with a 2-point cal system like the Apecs.

With a one point cal, all you need to do is check is if any cells do not fall back to 0.21. If they fall back to somewhere above, you have a good indication of a dying cell, well before plunking yourself in the water with it.

Hi Guys. This thread is now 5 pages long but sadly very few cool user mods listed. As a brand new Meg owner, I was hoping to pickup some useful tips/mods from you experienced guys. Surely ya'all must have made a host of interesting and useful changes to your Megs?

Cheers
Mike

The post is about factory changes to the stock Meg. It (the Meg) is designed to be altered almost any way you want and I know of at least a dozen ideas posted here in Rebreather World. Get off your

and search. (no offence intended

)

This is an important thread for ISC to use so changes that we cannot make, be made for future versions.

Some links for your convenience.

http://www.rebreatherworld.com/megal...on-my-meg.html
http://www.rebreatherworld.com/offic...effective.html

the list goes on...not to mention what's in the library.

Bottom line is the Meg is nearly perfect because it is very customize-able to suit anyones particular needs, and built sufficiently robust to endure my abuse. Out of this whole thread, what I would like to see become available is;

1) Depth gauge & bottom timer on primary handset
2) Above mentioned 1 point cal
3) Lighter canister (but I would probably break it)

Nothing else really.

Hey guys,

i cannot believe that this tread got to 3-4 pages and there no picture yet so others can see what exactly you are talking about? i do understand what bolt snaps are, but with a picture one get so see, "how big?, how long?" where to attach? etc.

Please send some pictures if you can. it would be really helpful. it doesn't cost a thing, and instead you can help your fellow megdivers to better prepare their unit, or to realise how it wouldbe before they start to adjust and maybe not being able to bring it back before to is original state... i.e counterlung velcro being cut etc...

Thanks.

Spyros

I also attach the counterlungs in this way. A while back I posted photos of my method here.

Aaron, dude, go look at the date of that post... you too can have what was then experimental, by upgrading to 2.06. Please dont murder my paint job, its really awesome!

As far as mods, I have also now re anodized my can in Pepsi Blue. Still waiting for the sponsorship check though.

Also recently went to the new ISC wing and the armadillo sidemount system for my bailout, just used it very sucessfully for a shed load of cave diving, dont think I will ever go back to straping cylinders to my chest.

so, you want pics, here are pics, one is prior to side mount,with the cylinder hanging down, one is after with the 80 tucked nicely up behind and alongside.

O K . I guess this was my first and last post. I will just go back to diving and keep my opinions to myself.

Ron hi,

thanks for the pics. do you have more detailed pics of how you attach the upper clip of the tank to the armadillo? i 've had it for a while now but could not quite manage to attach the top clip to the upper sidemount. maybe is because i attach a pony tank on one side of the backplate and a solus 2500 on the other.

so, some more pics which will clearly show this would be great.

Thanks.

On my COPIS 1.0

->Cut away velcro (who needs all that velcro?)
->Added Armadillo sidemount-stuff -very good, 3-4 stages out of the way, no problems.
->Added Shearwater triple-HUD (No hud on copis 1.0 from factory) -This also works excellently -handset is now backup.
->Added factory-kit for VR3 -no big success. cannot get it to read correctly, and yes I moved O2-addition to the other side.
->Switched to radial-scrubber from Golem (Not yet wet!) -No test-data yet...
->BOV will be bought soonish, probably Golem that too.

Not sure what you mean Spyros, I have one photo below of me with a bungee that was too long. Subsequently shortened, and I also like to wrap the bungee around the whole reg.

The sidemount is amongst the first recommendation I would make

(fantastic illustration by Micjan above). Readers take heed!

Following your request for CL attachment photos, I attach the following photos (bit of a challenge with a mirror and phone cam.

photo 2 attempts to illustrate how my CL's are clear from my belly area and go under my arms. In a recent wreck trip to Coron Bay in the Phillipines, I out penetrated the pair of Evo divers

I was with and entered any space the single tank OC guide did, carrying an 80 cuft stage.

Advantages: 1) Easier gear-up (no CL's to attach) 2) Better streamline 3) Better CL protection

Disadvantage: 1) Bit of getting used to

photo 3 shows how I simply use a double section of thick bungee and a quick-link tied to a bottom hole in the BP. The upper CL's are only attached by the velcro strap going around the harness and the loop.

Crap photos I know, but hopefully you/others get the idea.

hey Gilles,

thanks for the pictures. very nice of you. BUT, do i get the feeling that you use the counterlungs in the opposite way? from your picture it seems that you have the right CL on your left....am i right? why is that?

secondly, how to you attach the tank? do you use a dogclip, or just put the bungee around it?
