Sea fishing olive lead sinker with Tongxin scale pattern, rugby-shaped electrolytic lead construction with inner plastic core, available in weights from 10g to 150g for saltwater and freshwater fishing tackle rigs
Tongxin Scale Pattern Olive Lead Sinker with Plastic Core for Sea and Freshwater Fishing

This olive sinker combines functional design with practical specifications for anglers targeting a variety of species and environments. Its defining rugby shape and textured Tongxin scale pattern are not just aesthetic; they contribute to a lower profile in the water, which can help minimise snags on rocky or weedy bottoms. The use of electrolytic lead ensures a uniform density and weight consistency, which is crucial for achieving predictable casting distance and sink rate. With a comprehensive weight range starting at a light 10g and extending up to a substantial 150g, this sinker series allows you to fine-tune your terminal tackle for everything from light ledgering in a calm lake to holding bottom in stronger coastal currents.
Features and Construction

The construction of this sinker focuses on delivering reliable performance through its material choice and internal design. The electrolytic lead body provides the necessary mass, while the integrated features address common fishing challenges.
Material and Build
The primary material is electrolytic lead, chosen for its purity and consistent properties, resulting in a sinker with reliable weight and casting characteristics. Internally, it features a plastic core manufactured via injection moulding. This core is not merely a filler; it creates a different density profile compared to a solid lead sinker, which can subtly affect the sink rate and how the sinker sits in the water column. The core may also provide alternative attachment points or influence how the sinker balances on the line.
Size and Practical Fit
The most critical sizing specification is the weight, offered in 11 distinct increments. Starting at 10g for very light presentations or delicate fishing, the range progresses through intermediate weights like 30g, 50g, and 80g, which are common for general coarse and sea fishing, up to the heavier 120g and 150g options suited for deep-water sea fishing or fast-flowing rivers. The rugby shape, wider in the middle and tapered at the ends, helps the sinker roll more easily over obstructions than a plain round or barrel shape, potentially reducing lost tackle.
Uses and Placement

The wide weight spectrum and specific design make this sinker suitable for multiple angling disciplines and scenarios, from casual freshwater trips to more demanding saltwater sessions.
Event or Professional Use
For match anglers or those participating in fishing competitions, having access to a precise range of weights like 40g, 60g, or 90g allows for meticulous tackle tuning to meet competition rules and conditions. The consistent electrolytic lead construction means every 50g sinker, for example, will perform identically, removing variables. The rugby shape can be advantageous in commercial fisheries with clean bottoms, allowing for a neat presentation and quick indication of bites.
Everyday Home Use
The lighter weights in the series, such as the 10g, 20g, and 30g sinkers, are ideal for beginner anglers, children, or simple float and leger setups on local ponds and canals. The scale pattern provides extra tactile grip, which is helpful when cold, wet hands are tying knots or changing rigs. For the sea angler fishing from shore or pier, the heavier 100g, 120g, and 150g options offer the ballast needed to hold a bait in place against waves and tides, while the streamlined shape aids casting distance.
Benefits and Buying Value

Choosing this sinker provides tangible benefits centred on its specification range and construction, offering practicality and flexibility for the investment.
Reuse and Low Maintenance
Lead sinkers are inherently durable and designed for repeated use. Provided they are retrieved and not snagged and lost, a single sinker can last for many fishing sessions. They require virtually no maintenance beyond rinsing in fresh water after sea fishing to prevent corrosion. The plastic core is sealed within the lead, protecting it from water ingress and ensuring long-term integrity, making it a one-time purchase for each required weight.
Why Choose This Product
This product stands out due to its clear and extensive weight range, allowing anglers to select the exact gram weight needed without compromise. The combination of a rugby shape for better bottom interaction and a textured surface for handling is a practical design approach. The inclusion of an internal plastic core is a specific feature that distinguishes it from standard solid lead sinkers, potentially offering different rigging or performance characteristics. It delivers a focused solution: a reliable, weight-specific sinker with a considered design, supplied as a single unit so you buy only the specific weight you need.
