I strongly recommend against buying a SeaLife ReefMaster digital underwater camera. While their low-end underwater film cameras were a good buy, their digital cameras are not.

I purchased a SeaLife digital-camera/housing combination for over $400, only to discover later that the camera included in the package is a relabeling of the lowest-end, poorest-quality digital camera available: a $60 Vivitar not even sold by Vivitar any longer. The camera has problems with very basic functions (see flash discussion below) and consumes batteries at 3-4 times the rate of "normal" low-end digital cameras. These days you're far better off buying one of the many waterproof housings available separately from your digital camera: you'll pay much less overall and end up with a much higher-quality setup.

In addition, SeaLife customer service is problematic. I emailed a question about what turns out to be an undocumented flaw in the flash functioning of their cameras. In the initial series of interactions they cut-and-paste generic answers to questions that were clearly not the one I'd asked. Perhaps they were trying to hide the flaw or were simply not reading my email. Once they finally acknowledged the flaw they did not reply to follow-up questions. (Contact me if you're interested in details of the flaw, or seeing the email transcript.)

Again, I recommend against the SeaLife ReefMaster.
