The COBRA firing system consists of many devices, including the 18R2, 18M, 36M, 72M, and Audio Box. Firmware is the embedded software in our hardware that gives life to the device. COBRA is continually striving to improve our products, and as we add feature enhancements to each device, we release new firmware versions to support the newly added functionality. All COBRA updates are backward compatible and function within our universal system design where all systems work happily together in a single-family of products.
