Magnum radars are available with a transmitter power of either 4kW or 12kW. The 4kW output is great for collision avoidance, coastal navigation, and long-range weather detection. The 12kW output offers significantly higher power output which allows the radar to better detect and track small, weak, and distant targets. The 12kW option is extremely popular with coastal and offshore anglers for its long-range bird finding capability. The 12kW version is also an excellent choice for boats venturing far offshore, or who operate regularly in high seas or inclement weather.
