Yeah...I like the Lumix...its been a solid friend for a few years and the whole family uses it.
I managed to wreck 3 GOPROS....I just keep trashing them surfing as they tend to leak even if I clean the seals and re grease and carefully close the housing...but thats probably just me..if there is something that can be wrecked I can do it...I would love to hire myself out as a beta tester cos I can break anything

I have a Canon Video camera and water housing which is my goto underwater camera but it will set you back around $1400. It has not had any problems yet so there is something to be said about GOPRO's not being as good.
