Buoyancy Float Arm,DIVTEK Dive Bracket with Nauticam Bayonet Mount Improved Lightweight for Underwater Camera Tray Scuba Dive Video Lights Arms

I purchased two of these and two larger ones for my D800 with and Aquatica housing. Honestly, it was too much. The camera was a pound or two buoyant. I think 4 of these would have been perfect. I had to tighten them up before using them. I think they came lose in shipping. Overall they are tough, light, and look great.

So I took this in an 8ft pool to check bouyancy on my camera.Then this week (Feb 18th 2024) I went to Cayman Brac. At the end of the trip the float was 90% full of water. I never saw bubbles coming out of it nor could I get the water out. Depths of 60-100ft on the dives (17 of them)I wouldn't waste your money. I'm dissapointed

The media could not be loaded.  Update (June 16, 2024) - The seller sent me 3 new float arms to replace the ones that had leaked. I dove with them on a dozen dives last week (max depth 105-feet). On the plus side, two of them had no leaking issues, but the larger one did and is now filled 3/4 full of seawater. Hopefully they replace it with a non leaking one this time....Original Review:I bought 4 Divtek float arms to equalize the negative buoyancy of my camera rig. The buoyancy of the 8-inch arm measured right at 135g as advertised. The 10-inch arm measured at 250g, so a little more buoyant than advertised, but actually perfect for my rig.Dry (and in shallow water buoyancy testing) they looked great and I was very happy with them. However, 3 of the 4 leaked (significantly) within the first 6 dives (less than 80-ft deep). One of the 8-inch is half full of water. The 10-inch ones are both about 20% filled with water. There is no apparent seal or other way to drain them. Also not clear how the water got into them. Don't waste your time with these unless they fix the leak issue.

For what I had to pay for these arms, very disappointed to get one with O-rings and the other with non. what's the deal with that. Poor quality control?? I tried to work with them, They made me promises and didn't follow through with them. I don't recommend them to any one. and the whole exchange thing with Amazon was a nightmare. Talk about disorganized.

I'm using this to get the buoyancy right on a camera setup I use for diving. I've only testing it quickly in the bathtub so far but it seems more or less alright.I will add more information once I have it. But the float seems to be as advertised, but nothing exceptional.

My float arm leaks water into it , useless

I selected this rig to make my camera rig less negatively buoyant. After all the brackets and lights, I found the camera to be at least a couple pounds negative. This led to some steadiness issues. With the float on the top of the double handle rig, the centered upward force helps with handling.Construction appears to be a dense closed cell foam over a rigid core. The ball ends are within tolerance and the o-rings seem to be of the right durometer. There is an M5 socket to attach additional items but I do not have any accessories to use there.I can't speak to long-term durability but in several freshwater dives in murky water, it has not corroded or appeared to decay.
