NextCast Core16 Body Sink3/Sink5 is an innovative sinking head body designed specifically for demanding fishing situations. This short head works excellently with a heavy 15-foot sinking tip, even up to T18. It effortlessly and smoothly turns over heavy tips and flies, making it an excellent choice in tight conditions.
When choosing the Core16 model, it is important to select a slightly lighter weight compared to traditional Zone lines. For example, if you usually use a 600-grain Zone line, we recommend trying the Core16 at least 50 grains lighter.
The product information is clear and practical, making fishing easier. The ready-made loops and line markings make it effortless to use.
Core16 makes using a sinking line easier than ever before and is a great choice for tight and technical fishing spots.
