With these weights, you ensure that your camera is not going to float. You attach them to your Canon underwater housing so that it gets enough weight when the density of water is too high. Depending on the water and the weight of your camera, a different number of weights is required. Compatible with almost all Canon underwater cases.
The set consists of 4 weights with plastic pins to fix them together. Using the supplied screw, you can assemble them easily to your underwater housing.
