SeaLife recommends using SD or SDHC memory cards up to 4GB, which will take about 1500 large size, fine quality pictures or at least 30 minutes of continuous video. We recently tested 8GB and 16GB SDHC memory cards from popular brands like Sandisk, Kingston, PNY and Lexar without encountering any problems.
SeaLife no longer recommends using ONLY SanDisk, Panasonic, or Toshiba brand memory cards. Our testing over the last several years indicates that these brands are reliable cards, but many other brands have also proven to be just as reliable. We have not found any compatibility problems with brands like Delkin, Lexar, Kingston, PNY, Kodak, Polaroid, Kingmax, and Eye-Fi (wifi card). SeaLife cameras are designed to work with any brand of SD memory card.
