I am slowly gathering equipment to take my Canon 6D underwater. I am acquiring all Ikelite products (housing, strobes, arms, ports etc) and I have no idea what kind buoyancy this rig would have. From experience, does this setup tend to be positive, negative or neutral? Would I need buoyancy arms and if so, what kind would you get?
I have two Ikelite i60 strobes with Nimh batteries. In order to achieve neutral buoyancy with these attached I have added floats that displace over 1.5 liters of water. However, Ikelite's newer 160/161 strobes have lithium batteries that each weigh 800 grams less than the bateriies on my strobes - you might need any kind of floatation if that's what you're using.
