This product can both be used neat or mixed with your chosen groundbait mix. Ideal when fishing in clear waters! Perfect to use when the fishing is expected to be difficult. Used neat Black Earth is the perfect aid to “transport” livebaits such as jokers, bloodworm, maggots, casters or worms to the bottom of your chosen fishing-spot. It is the best to use Black Earth when fishing in still and/or slow moving waters (canals, lakes and rivers), while the Black Earth Heavy is the ideal in deep and fast flowing waters.
