Dynamite Swim Stim Match Groundbait 2kg: Margin Mix, the ultimate solution for targeting big carp in commercial fishing. This unique blend combines SwimStim Koi Technology with a selection of secret ingredients specifically designed to attract large carp. When mixed slightly wet, it creates a fine cloud that instantly draws fish in, but disperses quickly to prevent liners. The inclusion of larger particles ensures that the carp stay focused on feeding on the bottom.
