Halcyon ACB

[KOMPRESSOR]

Kompressor,

Like you I dive with a thick neoprene dry suit (Poseidon unisuit, 6.5mm), and also have a 40LB Halcyon Eclipse rig for single tank use. I tried the ACB 20 system and found that with hard weights it would not take the 4.5Kg or 10lbs of weight as stated. Using soft weights though it was no problem. Using the ACB system with my Helios light was another matter entirely; not the best for either ergonomics or practicality, as if you wanted to remove the canister for whatever reason, off must come the ACB first.

Together with the Helios and SS BP, I found that I needed 6KG in the ACB. To eliminate the ACB's I switched to a weighted STA and used trim weights on the tank bands. The trim weights were the ditchable type, so in an emergency I could ditch 5KG there and my canister light, now secured with a spare SS weight buckle. However, unless I had a flooded dry suit this shouldn't be necessary. A friend has an Agir-Brokk SS backplate 6mm thick and 5.1Kg. This would obviously take some weight from your belt, but like me you already have the Halcyon plate and using the P-weight almost takes you to 6Kg in any case.

Regards,

Charles

Thanks for your info, this could be useful. Danger is to become overweight up front, and thereby tip foreward. I am not quite finished getting my trim right, but I'm getting there. A 5mm plate would definitely do off with my trim, since my 12L/300 bar tank already weigh 17,5 kilos + the 3700 litres of air...

I haven't gotten a P-weight yet, but I'm looking foreward to testing it.

Has anyone used the DUI trim system with a BP/W? I hate a regular weight belt with a lot of weight on it (which is what I need to sink my gigantic self and a boatload of neoprene). I've used the DUI system for freediving and really liked it, just not sure how/whether it's going to work with my backplate.

Incidentally, my BP/W came with the ACB system, but I may be selling it (the ACB) for cheap if the DUI thing works. The ACB is nice, but it does take up a lot of space on the belt and doesn't hold enough lead for me (not sure which one mine is, but I'm unable to cram more than 7 lbs. of softweights into each side).

I use a BP/W with the DUI harness system. They work very well together. If I had to, I could probably fit 2 10lb soft packs into each pocket, and there are 4 pockets so I guess you can load up with 80 lbs if necessary. I'm not sure the system would hold up well with that much weight, but it's possible in theory. Why you would ever need 80lbs is another story. Maybe if you are trying to anchor a hot air balloon 100' underwater... I dive with about 14-16lbs in mine and it's perfect.

Zeagle has the Zip touch that seems handy then the ACB they are webbed to the backplate.

Any thoughts if that would be convenient with Halcyon. Did any body try them
