Been using a Canon housing starting back in 02 with the s30 and have many dives to 130 with nary a leak in the bunch......keep the o-ring clean and greased and rinse well and you should have no problems.Peter_C:I have had my Canon housing to over 80 feet for many many dives without any problems. Not sure I would push it much past 95 feet or so though. Most of our dives here are shore dives.
