    WOB is just fine. It ships with either a gg or dive soft bov or a gg dsv. Mavs and adv’s built into bov’s sucks.

    I did some playing around with the Fathom this week to get the backmount bailout configuration dialed in. It's effectively the same as my OC doubles rig now, but with a rebreather in the middle.

    I'm using twin LP50's with LOLA valves and a manifold, then my regular OC backmount regs. Right post is 100% standard, 7' hose, wing inflate. Left post is standard short hose, pressure gauge, and DIL fed through a QC6. Oxygen is a 2L LP cylinder mounted onto the can with a standard pony mount (I'm using a Highland mount).

    Test run was a 100 minute swim around Devil's Eye cave. It was absolutely stable and clean and when my dive was over, I simply had one trip out of the water. I'm looking forward to diving this rig off a boat next month, it'll also likely be my go-to bailout rig for teaching CCR cave moving forward.

    Very interesting stuff, I didn’t know they were 300bar capable and I guess it stands to reason the standard is very high and barely achievable at that.

    I take it your drysuit is coming off the tiny inflation bottle in the pic?

    Looks good Ken. Do you have a picture from the top showing how much the O2 bottle adds to the profile?

    Are you protecting the can in anyway with a cave shield or similar?

    Yes, that's a drysuit bottle.

    No photos of it from the top right now, and I've got it stripped back down for my dives this weekend. I'll get some photos of it next month, but the profile with the 2L is pretty low. I was able to squirm through stuff that's pretty tight in 104's.

    I'm using one of those mounts (in the same basic place) for a 13cf suit gas bottle behind 2 conventional 3L CCR bottles. Seems really big to me, but when the water is frigid (<5C/41F) and esp. when I am doing free ascents I tend to use a lot of suit gas. It is at least far more secure than my old Velcro straps.

    I'd like to see those photos when you get them. I'd also be interested in seeing what the whole system weighs compared to a set of 85s or 104s. Is it a pain pulling it all apart? It'd be nice if the 50s could just slide off without having to take apart the lola valves

    Can you reach the valve on your O2?

    Yeah, very easily. Not sure if I could if I was using 85's instead of the 50s though.
