    Does anyone add weight in their Counterlungs

    Not sure if all the other brands have built in weight pockets, but the Hollis Prism 2 has weight pockets in both counterlungs. I have never used them, just wondering if anyone has?

    Best regards,

    With two AL80s sidemounted, aluminum backplate, drysuit with 200g undergarment... I can just sink with no weight in my counterlungs. I dive with three pounds in each one, in case I have to bailout and those tanks get floaty on me.

    Hi Chett, P1 has the same pockets. I tried them for trim adjustment and found them to be ineffective for helping with horizontal trim because they are too low, uncomfortable and they pulled the CLs further away/down from my chest when in a horizontal position. Further, the zippers for the pockets routinely come undone and have to be re-secured. A better idea would have been to provide weight pockets to mount on the tops of the cylinders. That would have almost certainly been cheaper and would have been more effective in achieving horizontal trim. I can't figure out why that feature of the P1 wound up on the P2, yet an improved analog secondary did not..! -Andy

    Hi Andy,

    I can always count on you as being one of the top Prism Topaz aficionados. I know you have countlesss hours on the water. I have never added any weight in the Prism Topaz or the Hollis Prism 2 inside the counterlungs. Just wondering about it.

    I add 2 pounds to the top of each steel 3 L tank. Totaling 4 pounds. The problem is finding the correct cam band and weight pocket. Somebody made me a pair of custom-made cam band with Velcro to hold a 2 pound lead weight that I attached to the top of my tanks. A few weeks ago during a dive (1) fell off and I lost it. Now I'm using a makeshift stainless steel hose clamp and a crappy weight pocket.

    On the same subject, I want to eventually put my first stage regulators and steel tanks and valves both of them on top of the unit rather than the bottom of the unit. This is how the Poseidon is set up. I know some will argue that it's harder to turn off the gas if necessary but I want to get the weight of the first stage regulators and tank valves off the bottom of the unit and add it to the top of the unit. Once I do this I will post some pictures. I think overall this will help the trim getting the weight up higher on the unit.

    Best regards,

    Re: Does anyone add weight in their Counterlungs

    When teaching we start off using the CL weight pockets to get a target total weight needed, then put on our custom H plate weight pockets and cut out the CL pockets. This gets us where we need to be and makes the CL's sit very close to the chest, very thin and even, this helps the ADV fire properly.-Eric

    Hi Chett, your call on inverting the tanks, but then you will probably need a stand to keep it sitting upright on deck? Peter told me the reason for the Prism valve down orientation is exactly what you mentioned, it's easier to open/close them down, and thus safer. Having jumped in once or twice without turning the gas on, I second the notion. I'm not perfect and having the valves up may have turned what was a silly mistake easily fixed in 2 seconds to something that could've killed me. Frankly, I'm baffled why this isn't part of CE standard, seeing as how those EU technocrats have supposedly thought of everything in their quest to save us all from ourselves.

    SS clamps and basic weight pockets on the cylinders should easily solve it. I have the fiberglass cover on my P1 and zip tied pockets to the top of the cover, works great with the weight up as high as it can go. But alas, no full cover for the P2... -Andy

    I'll try to take some and post them up. Prissy the Prism2 has gone through quite a few changes since she and I went on our first dive together.

    First Configuration:
    Standard out of the box. Use counterlungs as shoulder straps. Added Golem buttplate, Edd Old School bungees. 5lbs each counterlung, 4lb sausage weight on backplate, 2lbs clamped to "top" of each cylinder. Hollis F1 fins, drysuit with 200g undergarment.

    Second configuration:
    Swapped backplate for stainless, swapped Golem butt plate for Dive Rite Tech buttplate, ditched sausage weight.

    Third Configuration:
    Swapped stock wing for Hollis SMS75 wing, ditched weights on tanks.

    Fourth Configuration:
    Dropped to 3lbs in each counterlung.

    Current Configuration:
    Using modified SMS75 BCD. No backplate. 3lbs each counterlung. Deep6 fins.

    Buoyancy control and trim have improved along the way. Can't say if it's the tweaks, just becoming more comfortable on CCR, or both. Don't guess it matters much.
