The Prologic C-Series Pro 2+1+1 RG Bite Alarm Set is a complete bite detection system for carp and specimen anglers. The set comprises two bite alarms, one receiver, and one bivvy light, all housed in a rubberised, weatherproof casing. Each alarm offers adjustable volume, tone, and sensitivity, plus a drop back differential that signals by both sound and light. A built-in night light aids visibility in the dark, and a 2.5mm socket allows connection of illuminated hangers or swingers. The receiver communicates via light, sound, and optional vibration, with a reach of up to 100m depending on terrain. The bivvy light is USB chargeable, while the alarms require a 9V block battery and the receiver requires three AAA 1.5V batteries (none included). The set is CE certified. - Rubberised housing - Drop back differential by sound and light - Adjustable volume, tone, and sensitivity - Night light - Alarms requires a 9V block battery (not included) - Receiver requires three AAA 1.5V batteries (not included) - Bivvy light is USB chargeable - CE certified - 2.5mm socket for illuminated hangers or swingers - Receiver signals by light, sound, and vibration (optional) - Up to 100m reach (depending on terrain) - Weatherproof
