Question Choptima Rebreather Users and Trimming

[inquis]

Some use a strap & boltsnap to attach the Choptima behind their neck rather than clipped to upper D-rings. I'm not a choptima diver, so just throwing it out there for thought.

For different reasons we have the same problem with our Se7ens. In configuration we have them they're insanely "ass heavy" and even with floaty fins turn us upright in seconds.

The only solution we came up with that works - lead on shoulders on the harness. Perfect trim, no more problems.
Lead is where lift from lungs / counterlungs is, can be adjusted well.
Working on printable releasable attachment.

Maybe I'll try straping a piece of lead to my helmet. Adding and removing weight to the harness is not a great option for me.

I would love to see some pics!

Your neck likely won’t appreciate this very much. Obviously a slew of possible outcomes, but what harness is it such that you can add lead there (if that ends up being the optimal solution)?

I don't think that is a good solution.

Throw a soft weight in the front pocket?

Are you diving dry or wet? When going from OC to Choptima, right now I add I think 3 (maybe 4) pounds to the topmost weight pocket in the Katana and on top of that just move the drysuit bubble moreso into my feet intentionally and it trims out fairly well. I'm still playing around a little with the exact weight, but a drysuit helps with the trim.

I did also move the unit a little higher on my chest from where I started, that's another lever to play around with but sounds like you already are.
