Communication is key and the DR-1 Commander will keep all your communication devices in the right place at the right time. Almost a twin to the RCP-1 Pro radio chest harness model -- the DR-1 Commander comes equipped to hold two BK/800 MHz radios with two main radio holsters on the front plate. We incorporated all the RCP-1 Pro features and designs our customers love into the DR-1 Commander to make it the ultimate dual communication radio chest harness. The DR-1 Commander dual radio chest harness works great with or without a backpack. When wearing this unit with a backpack you can either use the supplied torso straps or purchase the Harness Converter Kit. The Harness Converter Kit allows you to attach the DR-1 Commander to the shoulder straps of any Coaxsher backpack. iPad mini with protective case fits into the large main compartment.
