Arrow/Feather tracers are meant to give you increased downrange visibility. They also double as an effective wind check! With today's high speed bows and faster arrows seeing where your arrows go is an advantage. These bright colors will help you track your arrows in flight and if you ever miss your target will aid you in finding your lost arrow.
Tracers are easy to install and come in 12 count packages. Tracers will not affect arrow flight when installed and waterproofed correctly.
