Fish will pick up your bait and never know you're there until the hookset because your sinker will slide freely up the line. A high-impact black sinker slide is attached to a sturdy No. 5 Duolock snap. Per 25.
I use these to fish live bait for flounder. I went fishing with an in-law's friend and it was the 1st time I'd seen them. They worked like a charm so I bought some for myself.
The concept is great, from catfishing on the river to surf fishing. This sinker slide works well with lighter weights - up to 4 oz. It has lasted cast after cast and has assisted in catching a lot of fish. NOT recommended for use with the heavy weights. They break easily (about a dozen casts) with 7 and 8 oz weights.
