I have a virtually new Canon U/W housing for the G9. It was 12" underwater once to photograph ducks from a canoe. I sold the G9 and replaced it with a G11 and the housing is not compatible. In original box.
$110 and will ship to anywhere in US, shipping included. Less than half of new. All others, inquire.
