This leadcore is an outstanding product and totally exclusive to The Fishing Bag. Unlike other leadcore it has a woven, nylon outer coating. This is designed to trap mud and silt particles, helping the leader to blend into the lake or river bed being fished. The last three feet of an angler’s terminal tackle is the most important and this leadcore really does improve presentation around the hook bait. It comes wound on 10 and 20 metre spools.
