Thank you both for the posts! We already had the strobe from the other housing he had which worked concurrently. unfortunately, while the camera took great pics, it took on a bit of evaporation/water (more water or there would`ve been less worry to decide about the second dive) so as a result the pics were great as the card held them, but after one dive the dig camera did not work. I called the service center and got authorization to send it back for a new one and/or repair as all tests were followed. Just sent it out w/ the auth number this week - hope all goes well in that aspect. Other than that the photos captured were good, the strobe helped as well.............not upset about the purchase upset it failed but atleast pics were not lost and the camera will come back soon - christie
