I have a Intova IC600 the case is rated to 180FWS which is well within the range I dive. I agree with Scuba Rich if your gonna dive and shoot get a camera and case that will go well beyond what you think your gonna dive. Dont waste the cash and then go for somthing better. The intova is a good camera to start off with, I spent 250 for the hole works camera, case, red lens, strobe, fiberoptic cable. If you view my vids all where shot with the camera, in about water from 25fsw to 100 fws, if its a shaws cove vid its around 35 to 40 fsw. I do recommend you spend the money and get rechargeable battries as to the fact when you shot video it eats battries, I use Polaroid, spent 20 bucks for battries, charger, and extra sets for camera and strobe.
hope the info helps
