Today's professional digital cameras capture the highest resolution images ever, at lightning fast speeds. The large images they produce, however, can load your cameras buffer and ultimately make you wait to take the next picture. PROMASTER's Professional High Speed SDHC Secure Digital memory card is designed to give you the fastest performance SDHC enabled camera or device. The Secure Digital 2.0 standard (SDHC) is NOT backwards compatible and requires SDHC compatible devices in order to function. PROMASTER memory cards feature a LIFETIME WARRANTY.
