The Whistler WS1010 is a handheld analog scanner that can store up to 400 of your favorite frequencies. This model features Data Cloning with other WS1010 models and PC-updatable database capabilities. Its Service Banks enable you to easily locate types of calls by searching pre-programmed frequencies in separate marine, fire/police, aircraft, ham and weather banks. The dedicated Skywarn button allows quick access to frequencies used by storm spotter networks. Additionally, this model features Whistler's Spectrum Sweeper, a powerful tool which helps to rapidly detect, monitor and store new frequencies.
