Excerpt: 4 weights recommended for G10 = only 1/2 lb, so a convenience not a necessity. Neutral bouyancy w/ weights; w/o weights Canon G10 UW housing is like balloon attached to your wrist via strap. Although I tightened screw, bumping rectangular weights had enough leverage to loosen and those weights are now on sea floor in Belize. Bought another set plus stainless lock washers.
Excerpt: You are going to need these weights when using the Canon waterproof cases under water. Got these for a WP-DC28 case for use with the Canon Powershot G10 camera. Why not make your underwater experience as carefree as possible? Very easy to install on the case.
Excerpt: If you are diving with your camera, this weights are definitely a must! I used 3 of them as recommended by Canon, and the neutral buoyancy was perfect. I could just let go of the camera at 50 feet and it just stayed there floating in front of me.
Pros: Easily Loaded Equipment, Strong Construction
Excerpt: With a positively buoyant camera housing like the Canon housing for my G12, the camera is a hinderance when you need your hand (camera is typically on your wrist secured by a lanyard) to do something dive related (inflating a safety sausage for instance). With the weights you can make it less positively buoyant or negatively buoyant depending on the risks and issues you expect on your dive.
