I searched for some alternatives. And I was surprised na meron nga!
this one looks perfect for my Canon Ixus 85
This is DiCaPac. Or short for Digital Camera Packaging??Whatever! Im just amazed! It claims to be 100% leak proof. I have read some reviews, and OK naman. It is safe to use up to 5 meters or nearly 16 feet deep. Ayos na to for simple snorkling, etc. So how much is it? Just 1350 feysus! Perfect alternative kesa bumili ng underwater camera or the super expensive case.
And of course, meron din for SLR cameras. But I think it's harder to risk an SLR than a point and shoot camera. (--,)
