Canon WW-DC1 Accessory Kit (9876A001)

Weighted the case like a dream! Two weights made the case and camera neutrally buoyant in saltwater. Worked great while diving.

If you are an underwater photo geek you gotta have these weights. They keep your camera at neutral bouyancy. It doesn't sink or rise to the top if you happen to let go. Makes it easier to swim with the camera too

In order to make your Canon underwater housing either negatively or neutrally buoyant, these weights are a must!

I bought these weights for my DC35 waterproof case for my Canon S90. I was told that if you're going to be using the camera underwater, this will make things much easier. This could not be more true. Without the weights your arms will get too tired underwater. I'm sure there are ways you could make the water proof case not float without these weights, perhaps by attaching a weight of your own, but this fits the waterproof case perfectly.

I found they got in the way, but they did add the necessary weight to stop the camera from floating. I was not underwater for long, so I didn't need them. If you were a diver you may find differently.

Keeps your UW housing from floating, which is a real pain when scuba diving. Not really needed if only snorkeling.

You'll need them if you're going scuba diving. May not need them for snorkeling. They make the camera/case easier to handle when it is underwater.

Easy to install, made the camera neutrally buoyant. Worked well.

Cons: Not VersatileShould have used lock tight, first dive, tightened with a coin, came up with no weight. Now I have to purchase another set...not good...

These weights are a MUST for using any of the Canon underwater housings when diving... if you only snorkel or are concerned about keeping the camera protected when boating or at the beach, they're not so important - as a matter of fact, you may prefer to have the housing float if you're not underwater, you don't really want it suspended below the surface, or heaven forbid sinking, if you don't have dive gear handy. I have been a professional dive instructor, a commercial underwater diver and now am a marine surveyor. I have spent a lot of time taking photographs in and around the water for the last 18 years. Some of my work is done at the surface and some underwater with SCUBA equipment, but recently, most of my usage of the Canon underwater housing has been taking shots while in the water escaping the tropical heat watching (and photographing) the sun going down. For something like that, the weights are not necessary. If you are going to use the system diving in fresh water (lakes or springs) chances are you'll need to experiment with the number of weights needed; I find that 3x as recommend for the WP-DC21 and the Canon G-9 is perfect for tropical salt water diving. These weights, and the retaining screw are all stainless steel. That said, stainless steel still rusts (stains) only to a lesser degree than plain steel. You'll still need to take proper care of the weights just like you'll need to take care of the housing and O-ring. I normally carry a bucket and a gallon-jug of fresh water with me so that once I've finished diving/snorkeling, I can submerge the camera/housing/weights completely. I normally leave the rig submerged overnight or, if pressed for time, a minimum of 2-hours. Additionally, I remove the weights between uses and polish with stainless steel polish whenever I see the beginning of any corrosion. Overly conservative? Probably, but I've lived in a corrosive, salt water environment for almost 20 years and have learned alot about taking

Pros: Protects your investment; Functional; Easy To UseAlthough often skipped these weights allow tihe camera to STAY PUT and not drift away if it gets away from you on a dive. They also prevent surge from making video look shaky

Pros: Functional; Easy To UseScrew rusts a little. Needs to be a higher grade of stainless

I have a WP-DC22 case that suggested using 1 weight. Without the weight the case was slightly buoyant, and slightly negative with the weight. The weight helps keep the camera vertical in the water, but how many underwater subject require a vertical camera? While diving I find I hold the camera horizontal, it was more of a strain and less comfortable to hold the camera with the weight. Also I think I prefer a camera that would slowly float to the surface if dropped rather than sink into the abyss. The weights might be more beneficial for a case that needs more than one.

Used in Hawaii for the first time. Thanks to another review I was warned it was needed. Only used one weight out of 4 and the camera sank. It screws onto bottom with provided screw (no tools needed). Also comes with extra screw and weights. No weights the camera floats, so if your not using it for diving, you won't need the weights. For diving use one weight and she will sink.

Easy to use and inexpensive. Someone should tell you that the necessary weight is not included with the waterproof case which floats.

Helps keep the camera heavy for when scuba diving with an underwater camera. Otherwise, you'll be chasing your camera to the surface if you let go or lose your grip. It only sets you back a few more bucks on top of the somewhat spendy casing. It's added convenience at a moderate price.

Overall, I am happy with this purchase. I used these with Canon's waterproof housing (WP-DC8) on a total of 6 dives and a couple of snorkel trips. However, I would like to make others aware of a couple of small points. You might think that there is nothing special about designing weights for a camera case, but after using these I can say there is some room for improvement. First, and most importantly, I never felt truly satisfied that the weights were secure on Canon's own case. If you grab the weights and give them a slight twist the screw will no longer be tight. The weights never came off, but it is all too easy to loosen them and I will probably find a way to add some grip to the screw the next time. Second, the weights are stainless steel, a fact that you will appreciate if you are making multiple dives on vacation. However, the screw that holds them on the housing is not, so my bottom plate has a rust stain as does the screw (it's quite silly really).

You really need them if you are going to stay under and do some great pictures.

Pros: Easy To UseI use this when snorkleing to assist in holding the camera down keeping it from bobbing around.

Pros: Good Depth Range; Water-tight Seals; Easy To UseCons: LeaksThe weights worked well, but fell off as the screw loosened. Not necessary for most diving

Pros: Multi single weighting; Helps for shot stability; Great buoyancy control; Easy to assembleCons: No info for weighting; Online info useless; Wgt amount only onlinei first got my underwater case and no weights,
bad idea! i fought the camera the entire dive,
and it was tough to hold camera to shoot while its tring to float to the surface!

Pros: Functional; Easy To UseFunctional set w/all the required weights necessary. I used it last weekend while diving and worked fine. Added just enough weight to neutralize the buoyancy on the u/w casing.
