The JRC Radar DR Set 2+1 is a bite alarm system designed for reliable all-weather use. It pairs two alarms with one receiver, built around ultra-bright, long-life LEDs and a 15-second afterglow period on both alarms and receiver to help you spot bites in low light. The system offers a 120-meter range in a non-disturbed area, with low battery warnings on both alarms and receiver to avoid surprises mid-session. Construction is all-weather, with a high impact ABS casing, reinforced screw thread fixation, and a non-slip rod support for secure positioning. - Each bite alarm operates on 1x 9V battery - The receiver operates on 3x AAA 1.5V battery
