On the back is a simple flip-up latch that exposes the innards. Here up to a 32GB SDHC card can be slotted in next to a battery pack comprised of dual AA batteries. AAs surely add some bulk and heft to the thing (indeed it is a bit chubbier than the ContourHD), but replacing them in the field is of course a snap, and Tachyon promises some extreme longevity: up to 12 hours on a pair of cells. We didn't get that far, but we did clock upwards of five hours and the battery gauge is showing full. Impressive. Tachyon also sells a rechargeable battery pack if you're so inclined. There's also a miniUSB port for pulling off files and a proprietary TV output jack as well.
