The Dam Illuminated Swing Indicator is easily adjusted in terms of sensitivity by moving the weight from front to back across the steel arm. The double ball-clip can be adjusted by hand so that whatever line you use, the swinger will always release properly. The LED inside the body of the swinger is perfectly visible after dark and the connector fits almost any bite alarm on the market with a 2.5mm socket. Never miss another take with these luminous swingers from Dam!
