the WP-DC70 is an essential purchase for any canon ixus 700 owner looking to expand into wetter territory.
It is tough and reliable and although initially a little daunting taking a camera to 40 metres, it quickly becomes routine, luckily very little maintainenece is required and an occasional check of the o-ring and all is good. spare o rings and silicon grease can be aquired but frankly they are not needed, i have used mine heavily for six months and its idiotproof, and really does take a bashing in its stride, getting in and out of dive boats not being the most gentle of activities.
Have tested the camera to depths in excess of 40 metres in this casing with no issues, occasionaly though the case will get condensation inside even with two bags of silica gel inside, with no silica gel it will mist very quickly.
the cse comes with a couple of straps for nexk and wrist and its fairly simple to attach something more sturdy, the case with camera is positively bouyant so at least if you do let go it can be retrieved (by someone) on the surface.
a good housing for a good camera with quick and easy access to all the controls, allowing full creative control at depth.
