Built with a rugged metal housing, the Steel31 Dual Slot CF/SD Memory Card Reader from Hoodman helps to improve your workflow with one card slot that supports CompactFlash media, while a second slot supports UHS-II and UHS-I SD, SDHC, and SDXC media. The Steel31 allows both card slots to be used simultaneously and connects to your host system using an integrated 3' USB 3.1 Gen 1 Type-C cable. To help ensure compatibility with systems that don't have USB Type-C, a USB Type-C to Type-A adapter is included.
