The RAD 390 serves as a simplified alternative to the feature-heavy RAD 490i and RAD 700i models. By focusing on core functionality, the unit offers drivers increased sensitivity to laser and radar signals while utilizing next-generation filtering to minimize false triggers from vehicle safety systems. This design choice addresses common driver complaints regarding excessive, non-essential alerts in modern traffic environments.
Cedar Electronics CEO Jonas Forsberg noted that the device is intended to remove the barrier between advanced detection and user-friendly operation. Beyond its internal sensors, the hardware features a seven-segment LED display and a redesigned low-profile adhesive mount for windshield stability. The device also supports firmware updates, ensuring the unit remains functional as roadside monitoring technology evolves. The RAD 390 is now available for purchase at Walmart locations nationwide and through the retailer's online portal.
