MINIFOCUS2PCS Carbon Fiber Underwater Float Arm, D60mm, 8'', Aquatic Arm, Buoyancy Provided 300g*2, Dual 1'' Ball Buoyancy Floating Arms Lighting System for Diving Tray Video Light/Strobe

This is a great set of mounting arms, seem bulky but they are not. And the buoyance feature really helps!

These work great for my setup, my camera will just float in place neutrally buoyant. Went down to about 45’ and my camera wasn’t hard to manage at all.

Really tough and light. Does de job perfectly and on budget.

My rig has a case, a single handle tray, and one strobe, and a net of 110g of buoyancy is not a lot. It was HEAVY in the water. In case you are wondering, I HAD weighed my rig ahead of time (camera, batteries, and all) and I figured is have a residual weight of 100-150g with these—just enough that I could set it down but that it wouldn’t sink much more than a few inches.I must’ve screwed up with the tare when I weighed it because when I reweighed my rig after my trip (without the buoyancy arms), it was nearly 600g!So you’re thinking why give it 4 stars when it was my fault? Because I’m not sure what kind of rig would benefit from such little buoyancy compensation. Maybe just the camera, case, and a cold shoe mounted light?

They work well with my housing and lights!

I couldn't notice any difference in buoyancy but they add bulk and weight on land and on the swim. I think they were a waste of money and I bought four.

One of the two floats filled with water and were useless within the first few dives with them.

Well made, perfect amount of bouancy for my U.W. lights!
