Keep your spot under control and see every movement with the Prologic C-Series Pro bite alarms. The alarms feature six different sensitivity levels, alert tones, and volume settings (including silent), allowing you to customize them exactly to your preferences or adapt them to the situation. This set includes a receiver and a wireless bivvy light. The C-Series Pro alarms help you determine exactly what is happening twice as fast thanks to an intelligent system that distinguishes between a take and a drop. When there is a take, the left colored LED lights up for 2 seconds; when there is a drop, the right white LED lights up. Additionally, drops always have the same low tone regardless of the other selected tones to help you recognize them easily. A 2.5 mm socket allows connection of an illuminated visual indicator, and the separate night light of the alarm activates by pressing a button. The alarms are also weather-resistant and feature a rubber casing to ensure durability over time. - Rubber casing - Different sound and light signals for takes and drops - Adjustable volume, tone, and sensitivity - Night light - Alarms require a 9V block battery (not included) - Receiver requires three 1.5V AAA batteries (not included) - Bivvy light is USB rechargeable - CE certified - 2.5 mm socket for illuminated visual indicators - Control unit signals via light, sound, and optional vibration - Up to 100 m effective range (depending on terrain) - Weather resistant
