Will it sink or will it float? G9 in Ikelite housing with DS-51 + YS-90DX

Hi, This is my first post on Wetpixel. I have enjoyed the content here and hopefully absorbed a lot of it. My thanks to all of you who have posted here.

I have a G9 that I have been using with a Canon case and a Sea & Sea YS-27 but have just upgraded to the Ikelite case with a DS-51 and a S&S YS-90DX Duo in TTL Slave mode and the requisite arms. I also will have an INON UWL-100 and UCL-165 hanging off of my strobe arms when not on the lens as well a small nano focus light.

My question is .. what should I expect in buoyancy? Will it sink or will it float?

I will find out in a few weeks when I can get it under the sea, but I would like to have some sense if I need to add positive or negative ballast to trim it out.

The neighbors pool isn't open yet :-)

Thanks!

Frank

It'll sink.

As Jeremy allready wrote, it will sink for sure. No doubt about it.

Might be a good idea to think about floatation arms or other extra buoyancy compensation.

Looks like Jeremy & you have pretty close to what I have.

Do you use flotation arms? Can I get away with some styrofoam "pool noodles" around the arms?

Thanks

if it helps my set up sinks

"Normal" foam will be crushed at depth and no longer work ...

ULCS and INON make special buoyancy arms and a company called STIX makes floats that attach to arms that won't crush.

Have you used it yet? I wouldn't worry too much about the negative buoyancy ... it isn't THAT negative ...

I dont use any floatation arms myself. And as Jeremy pointed out - it's not that negative... + I'm in good shape

I will be trying it in a couple of weeks in Cozumel. I'll bring some pool noodles and some pipe insulation with me to see how they fare. In fresh water it seems slightly negative now with some pieces of pool noodle.

I am used to the Canon housing and a YS-27 and this new setup feels a LOT heavier on land, especially with the INON lenses hanging on the strobe arms, but I expect it will be managable under the waves.

I'll let you know when I find out. The STIX floats seem reasonable.

Pool floats won't work ... but you'll soon find that out for yourself ...
