ISC Meg Modifications

[Dsix36]

I never saw the need for such a big inflation bottle. I used onboard dil for wing and 6cf for drysuit. Just my personal preference though and it made it much simpler to configure. It worked on a rEvo and a hammerhead so I would guess it would work on a Meg also.

Interesting. I don't have much space so I prefer AL13 on two dive days. With 6cf, I'd have to switch.

Here's two different dil-out configurations. Mine has the pair of 3 l and one I found on Facebook from Frederic Page is the one with the aluminum 40s.

Worth noting I had a shaved cave canister and currently use a custom cut canister latches are deleted now. But I made sure I could use the rear latches on the first version without removing the 3l.

Frederic has a standard can by the looks. And the 40s look like really nice rig to use.

@211ratsbud - that's hot! Can't see from the pic, but what mounts do you use for LP50s? Also, do you know of anyone trying to adopt Fathom's "heavy" cage configuration to Meg? If you call ISC and talk with them, you may be able to get an unshaved can.

For 3L tanks, see if you can use short Kent Tooling brackets - they beat shadow mounts. You'll have to have the pulls on the outside though.

L. No bailout to 3L here... I run a DSV with a bailout reg on my necklace; the reg goes to the primary bailout bottle I got on the left. Bailing out to 3L is a lol.

Agree. Was hoping the answer was no

I actually was wondering why that wasn't an option for him, but thought maybe I missed something. The fathom is very easy to set up a big onboard inflation bottle regardless of configuration. But if it wasn't, I'd likely just go backplate mounted suit inflation since its been tried and true for so long. Didn't know if it would be annoying with OTCLs though.

If you're not opposed to a stand, many of us in Norway use a variant of this setup. This is me with a chubby 2L tank for suit-inflation. I like the added height for donning/doffing, I'm 185cm.

I'm using the fathom brackets on the canister to hold the 50s. The shadow mounts by far hold tanks the closest to the canister. This allows everything to nest and be relatively lower profile. You can put a straight edge across the canister and the 3l and make three points of contact.

I cut my own canister from a tall one so I solved that.

This is the only other shots I have of it set up.

@rddvet - there are several options for securing the inflation cylinder.

1. Attach the cylinder to the backplate using the straps. It is the easiest option, but the tank may flap back and forth, and I did not like it. I haven't tried that option on my unit but have seen how it is done on other units and received feedback from the owners.
2. Attach the cylinder to another cylinder. That's what I did based on my "no flapping" and "can reach the valve" preferences.
3. Attach the cylinder to the can. I did that but chose not to pursue the option as I could not reach the valve.
4. Modify the canister by welding a JJ-style rail and attach the inflation tank to the rail JJ-style. I've seen it done on a Meg, but I did not want to basterdize the canister.
5. Add a stand and use the space between the stand and the canister for the inflation tank. See @ahereng's setup. I don't have a stand and don't want to get one.

Based on the inflation gas utilization, I see a 3L inflation tank in my future. No way I'd ride with a 6cf tank into deep caves. For shallow caves demanding a lot of inflation gas, e.g., Grand Traverse or Double Grand Traverse in Peacock, I'd use one of the bailout tanks with 32% for inflation.

Ultimately, these choices are personal preference. I've met people who prefer backplate tank attachment and would never attach a tank the way I did. And that's ok.

I looked into the option but did not pursue it - I have a standard can and a stand would make the unit too tall for cave diving.

Nice Metalsub setup you got there!
