My wife has been using a Canon G11 as a point and shoot on her travels when using her DSLRs was inappropriate or too cumbersome. She has also had considerable success using it with an underwater housing whilst diving/ snorkeling. However, on our recent trip to Heron Island, the G11 played up for a while. Fortunately it came good after a reset and allowed her to use underwater mode on her dives.
She is seeking advice on what to replace it with. So far she has been reading up on the Canon G1X II (with housing) and the GoPro Hero 4 Black (waterproof) and would appreciate members' thoughts on these.
Are there any better alternatives?
