The Fox MK2 Illuminated Swinger Set is a bite indicator designed to work with alarms that have a power out facility, illuminating to signal drop backs. Its head display mimics a Micron LED, while the streamlined attachment tabs and widened front end improve visibility. Rubber shock absorbers sit on the bottom of the head, and the spring-loaded adjustable tensioning system allows fine tuning. A fixed line gate system keeps the line secure, and the light reactive acrylic indicator head works with the included Betalight slot for low-light conditions. - New black finish - Illuminates when connected to alarms with power out facility - Head display mimics Micron LED to signal drop backs - Streamlined Micron attachment tabs - Rubber shock absorbers on bottom of head - Widened front end for increased visibility - Spring loaded adjustable tensioning system - Fixed line gate system - 80g sliding collar weight - Light reactive acrylic indicator head - Betalight slot
