Scale Tongxin Fishing Sinker: A Rugby-Shaped Lead Weight with Internal Plastic Core

This scale tongxin sinker offers sea anglers a straightforward weight solution. Its rugby shape is chosen to assist with casting stability and water penetration, while the internal plastic core, created through injection moulding, is a key feature of its construction. Made from electrolytic lead, it is available in a wide selection of weights to suit different fishing scenarios, from light shore fishing to heavier offshore applications.
Features and Construction

The sinker's design focuses on functional elements for fishing. Below is a breakdown of its material composition and physical specifications.
Material and Build
The main body of the sinker is formed from electrolytic lead, providing the necessary density for a fishing weight. A distinctive feature is the internal plastic core, which is moulded into place using an injection moulding process during manufacture. The exterior of the olive lead sinker features a scale-like pattern.
Size and Practical Fit
The product is offered in a comprehensive range of weight options. Anglers can select from 10g, 20g, 30g, 40g, 50g, 60g, 70g, 80g, 90g, 100g, 120g, and 150g versions. This allows for matching the sinker weight to specific rod actions, line strengths, and target depths.
Uses and Placement

This sinker is intended for use in saltwater fishing environments. Its design caters to common angling techniques.
Event or Professional Use
For competitive sea fishing or dedicated boat trips, having the correct sinker weight is crucial for presenting bait at the desired depth and maintaining a stable drift. The range of weights up to 150g allows anglers to adapt to strong currents and deeper water.
Everyday Home Use
For recreational shore or pier fishing, the lighter weights in the range (10g to 60g) are suitable for casting lighter rigs and targeting species in moderate conditions. The rugby shape can help with casting distance and accuracy.
Benefits and Buying Value

The value of this product lies in its simple, single-component design and the choice it offers.
Reuse and Low Maintenance
As a solid lead weight, the sinker requires no maintenance and can be reused repeatedly across many fishing trips, provided it is retrieved. There are no moving parts or components to service.
Why Choose This Product
This sinker provides a specific construction—an electrolytic lead body with an internal plastic core—and a wide weight selection. This allows anglers to source a weight that fits a precise need without requiring a collection of different sinker types, offering practical utility for various fishing setups.
