The JRC Radar DR Alarm Set 3+1 is a complete bite alarm system built for all-weather carp fishing. The alarms feature ultra-bright, long-life LEDs with a 15-second afterglow period on both the alarms and the receiver, so you can see bites clearly even in low light. A low battery warning is included on both the alarms and the receiver to help you avoid missed runs. The receiver offers a range of 120 meters in a non-disturbed area, and the whole set is designed to withstand harsh conditions thanks to its all-weather construction and high-impact ABS casing. Practical touches include a reinforced screw thread fixation for secure bankstick mounting and a non-slip rod support. - Ultra-bright, long life LEDs - 15 seconds afterglow period on alarms and receiver - Low Battery warning on alarms and receiver - Range of 120 meter in a non-disturbed area - All weather construction - High impact ABS casing - Reinforced screw thread fixation - Non-slip rod support - Each bite alarm operates on 1x 9V battery - The receiver operates on 3x AAA 1.5V battery
