With its light yet strong aluminium die-cast chassis, the TK-3301 is built to survive hard knocks and drops. And thanks to its sealed case, it offers reliable performance in severe weather and environments.
Even with the KMC-45 optional speaker microphone connected* it satisfies or exceeds the stringent IP54/55 dust and water intrusion standards, as well as the US MIL-STD 810 C, D, E & F environmental standards.
