A uniquely designed chain indicator you will not miss any shot with and will undoubtedly become a gem of every fishing gear. It is designed in a unique square shape, which totally distinguishes it from all other indicators on the market. Its body is made from a durable transparent plastic in 7 available colours. Thanks to this, everyone can choose their favourite, matching the rest of the equipment. Its colour can be further enhanced during the night fishing by inserting chemical light through the bottom. The line fastening mechanism consists of two ball surfaces, whose pressing force can be optimally adjusted by means of a locking screw. Delphin ChainBLOCK has a chain, threaded at the end, which can be easily screwed to the holder located on the ridge under the indicator. In case of bad weather or when fishing at a greater distance, the indicator can be loaded with additional HeavyBLOCK weights.
