The Nash Siren R4 Presentation Set and Bobbin Bundle pairs the Siren R4 alarm with the Night Glo bobbin, designed as a complete indication system for modern carp fishing. The R4 alarm builds on Kevin Nash's speed-responsive indication concept from the R3, aiming to deliver accurate, responsive bite detection across varied conditions, from English estate lakes to the demanding environments of European inland seas. Its Intelligent Sensing technology is engineered to filter out non-events, such as wave action or weed build-up pulling rod tips, while still registering genuine carp indications, giving the angler clear information on what is happening at the end tackle. The Siren Night Glo Bobbin serves as the visual complement to the R4, using an MMCX bayonet push and twist connection to draw LED output from the alarm. When the R4's Night Glo function is enabled, the bobbin provides a pulsing illumination that mirrors the alarm's LED activity, making bite detection visible in low light. The bobbin's design focuses on practical line management and clear signalling, with a range of features to suit different fishing styles. - Enlarged ball clip attachment for free line movement - Secondary grip clip attachment for slack lining - Flexible rubberised 10cm cable - Full range of matching coloured heads with pulsing glow that replicate R4 LED colours, plus a black head option with white LED - Small Bobbin weight 8gr
