Canon WWDC1 Weight for Canon Waterproof and All Weather Cases

Bottom line up front: I took off one star because it's very overpriced for nothing more than six pieces of stainless steel. (The price is not Amazon's fault - it's expensive no matter where you buy it.) I took off another star because I had to take extra steps to rustproof and secure it, based on others' reviews. I would rather have a system (like the one I borrowed) that worked perfectly right out of the box.I bought a scuba dive housing for my Canon point-and-shoot camera, and was pretty happy except for the excessive buoyancy. Yes, it was nice that if I let go then the camera would end up at the surface, but at the same time, it would have gotten there far faster than I could catch it. And taking pictures while fighting the buoyancy was a real problem - painful on the wrist, and hard to hold steady for good pictures.While at a dive resort, I had borrowed a vinyl-coated weight, which was exactly the right buoyancy, and rustproof, but was only borrowed during the trip. So I'd been looking for a replacement. This weight set was suitable for my purposes.Having read many of the other reviews, I knew that making sure it didn't come off was important. When I first installed it, I could tell that those reviews were accurate - no matter how tight I made the screw, just slightly twisting the stack of weights was enough to loosen the screw, and a few jiggles could definitely lead to the screw coming off and the entire stack ending up somewhere on the bottom. So I assumed, ahead of time, I needed to do something about that.I also noted in the reviews that the screw itself was not as rustproof as the weight plates. Since I dive in corrosive saltwater, I knew I would have to do something about that also.My "something" was two steps. First, I figured out the right number of weight plates that I'd need, and then I glued that stack together with superglue. Next, I dip-coated the entire stack in plastic (Minwax Polycrylic actually) several times, to get a solid protective layer. Then, I installed the stack on the camera, cinched down the setscrew, and coated the entire setscrew with more Polycrylic. Thus, the screw was rustproofed, and prevented from turning by the plastic layers.The result was a rather secure stack of weights that should not rust. The system performed perfectly on two snorkeling trips; the camera was well-balanced, and the weights didn't budge or rust.If the plates were vinyl-coated, and the screw made from stainless instead of chromed regular steel all the problems would be solved other than price.

The weights worked wonderfully but there were three things I'd like to point out before singing it's praises.1.) As I was diving with the camera, the weights eventually worked themselves loose and had to be tightened about every 2 dives.2.) The main screw that holds the weights together and on the camera (and that kept working its way loose) was the part that rusted, despite regularly soaking it in fresh water and drying it after diving.3.) I met at least 4 other people with a canon underwater housing and only one other had weights for their camera. Everyone else said they didn't really need them. As for the two of us that had the weights, we only used two from that pack of 4 and the weighted case bumped off of stuff because it was dangling below, rather than hovering with me.

I recently used these weights with the underwater case WP-DC31 for my Canon PowerShot SD780 IS. I went on a total of 12 dives with the camera and it seemed perfectly weighted although I never tried the case without the weight to see if there was a difference. I only gave these weights 4 stars because of the difficulty I had figuring out how many weights I should use. The website listed on the documentation was a dead end so I had to search for the proper website. I found it at the bottom of the following page (take out the spaces): [...] According to the website, my camera only required one weight. I read previous reviews so I put some pipe thread tape on the screw and the weight stayed secure through all 12 dives.

Works like it’s supposed to on Canon underwater housing. I put a drop of superglue on when I attach them as they do swivel diving if not secured ( and fall off : ( )

The Canon underwater housings are designed to protect your camera from the elements, whether they are sand, rain, pool, or ocean. For use on the beach, while snorkeling, or taking shots of your kids in a pool there is little or no need to worry about the buoyancy of your camera housing. If you free dive or scuba dive you do not want your camera housing floating out of your hands. These weights are an easy way to adjust the buoyancy of your housing. The kit comes with four weight plates so you can fine tune your housing's buoyancy. I prefer a heavier setup and have added an extra plate compared to what was recommended by Canon. I'm very happy with the setup and they are very easy to use.

I have a Canon A720 IS and followed the instructions for the number of weights. Took it to the pool and watched it gently and slowly sink to the bottom. I removed one weight and it now has a slight positive buoyancy which is what I wanted (although I wish it was little less). Before using this product my Camera was pulling at my arm through the whole dive always pressing me to get to the surface, now it only gently tugs.

I added the proper number of weights for my WD-80 case and was surprised it made the case not neutrally, but negatively bouyant. Meaning, if you drop it the case sinks to the bottom and not float to the surface. The negative wasn't great (or a drag while finning forward) but I was nervous especially on the wall dives over the deep drop-off (600M). I think I will remove so it's positive for future dives.

These weights work well. The only reason I'm not giving it 5 stars is that the screw must be tightened securely or it will fall out underwater. This was my experience. A replacement screw was easy to find at the local hardware store, but of course it was not as nice as the original thumbscrew. I just wish a small tube of removable waterproof threadlocker was included.
