The WTR-670 beltpacks are constructed of extremely light, durable cast magnesium. The detachable antennas are secured to the beltpack via threaded post connectors and thus will not break or damage easily. The beltpacks feature a low-profile volume control and a robust, distinguishable momentary latch talk button.
