Q: What kind of memory card does my camera use and where can I get one?
A: Models 11-8321, 11-0832, and 11-0831 use a SD (Secure Digital)card (not included). Model 18-0832(Instant Replay) uses a compact flash card(a 16MB card is included). Both types of cards can be found in most electronics stores and computer stores. Manufacturer and capacity of the card does not matter as long as you get the correct type of card (SD or CF) for your model of binoculars. Avoid the use of MMC cards (MultiMedia Card)in the models designed for SD cards, as the camera may not function properly and require resetting(remove the batteries, take the MMC card out, then reinsert batteries).
