Weighting housing for big dome port?

[Larry C]

One of the issues I'm encountering with my Fisheye dome on the MDX-D300 is that the whole rig seems about 2 lbs. buoyant with the dome, extension and 10-17 on it. The housing wants to turn its port upward unless I hold on firmly, and it's also playing heck with my trim and buoyancy. It's tough enough diving with a big lump like that without it screwing up your safety stops with funky balance, too.
Does anyone weight their dome? I was thinking of seeing if a tank weight or ankle weight might go around the extension to get the thing neutral.

Thanks, I hadn't thought of tape-a-weights. They'd probably work fine, though in my experience, the double stick backing can waterlog and fall off eventually. I might try them.

Larry_C,
you may get:
1. a thin sheet of lead (plumbers use them) and bend it around the "Neck" of the port.
2. stick-on balancing weights for rims

to keep them where they belong you can use self amalgamating tape, auto vulkanizing tape, rescue tape or what's called. once vulcanized, it won't open anymore also under water.

Thanks, Chris. Someone else recently recommended the same stuff for securing the safe second to a BCD fill hose after zip-tie installation. I might have to head for the hardware store and get a roll.

Chuck T. likes SB-103's. They look hefty enough to do the job!

No, Chuck T likes SB-104s. SB-103s are long gone, recalled and replaced with SB-105s
which are less wimpy than SB-103s, but way short of SB-104s.

And the SB-104 is positive in salt water.

My old Aqautica dome port came with a weight that bolted onto the bottom of the housing to counter the buoancy problem.
