Buoyancy Arms

[Richard H]

Anyone got experience of using these ?

I have a Canon G9, housed in the Canon housing and an ultralight rig with a single Inon Z240. I have yet to take it in the sea but it sinks in the bath. Anyone know if a single ultralight buoyancy arm will make this entire rig neutrally buoyant ?

Thanks

Hi Richard,

I don't have the exact same setup, but I have an SP-350 in the Oly housing with a D2000 and one 8" Ultralight buoyancy arm and it is still pretty negative.

I'm looking into adding Stix floats to see if I can make it closer to neutral.

Good luck,

Wally

I have a couple of ultralight bouyancy arms, and the floatation provided by the arm only seems to make that particular arm piece neutrally bouyant, and does nothing for the overall bouyancy of the rig.

There is info on ULCS web site at ulcs.com. Click on the "Arms & Clamps" section.

Hi Richard,

The Stix floats will give more buoyancy than the Ultralight arms. There's a set of 4 jumbo floats that will attach to the regular Ultralight arms that will give a total of 1.6 lbs of lift. You'll need two 8 inch arms to fit all 4 floats, but you may not need all 4 to make it neutral. You can use a fish scale and attach it to the housing with a string and put the housing underwater to see how negative it is and dial it in exactly where you want it to be.
