A fishing sinker device is configured to extend based on a coupling force of magnets. The fishing sinker device includes a main member formed at least partially of a magnetic material and including a lower coupling part, a sub member formed to be engaged with the main member with the same diameter, and configured to maintain a coupling force therebetween by a permanent magnet accommodated in an upper coupling part thereof, and an adjustment member added to at least one of the main member and the sub member to adjust a function thereof. Accordingly, the sinker which allows the bait to reach the desired depth during fishing have effects of increasing the usability since the shape and function of the sinker can be easily expanded matching with the type of fishing while maintaining the desired length and weight of the sinker by a magnetic force.

A slow sinking fishing weight is made from a material having a bulk density which is slightly greater than the density of water and includes deep surface channels that significantly increase its resistance to movement in water. The fishing weight has a sink rate in calm water which is less than one foot per second. The slow sinking fishing weight allows a person to more easily maintain the depth of the sinking weight and an attached lure while moving the lure through the water.

A fishing weight according to the present invention may include a main body member having a passageway formed through a medial portion thereof. The fishing weight may also include an outer coating that covers a substantial portion of an outer surface of the main body member. The main body member may include a combination of calcium chloride, magnesium glycinate, limestone, and water. The outer coating may comprise a combination of gelatin, calcium chloride and magnesium glycinate.
