Handheld Digital Recorder
One of possibly two-like props, possibly modified from a tire pressure gauge reader with added faux mic tip to cover valve connector, used by multiple reporters during the series run.
Most prominently seen in Season 2 during press conferences aboard Galactica during the martial law crisis and in the wake of William Adama's shooting, with like devices held by both Sekou Hamilton and Playa Palacios in "Home, Part I." Other reporters have held this type of device as well, suggesting use by multiple persons throughout the series.
