Sea fishing olive lead sinker with scale tongxin and plastic core, electrolytic lead rugby shape fishing weight with inner core injection moulding, available in 10g to 150g sizes for boat and beach casting
Scale Tongxin Olive Lead Fishing Sinker with Plastic Core for Sea Angling

Designed for sea anglers, this olive lead sinker combines a dense electrolytic lead body with a distinctive tongxin scale texture and a lightweight plastic inner core. Its rugby shape is engineered to cut through the water with minimal resistance, aiding both casting distance and the stability of your terminal rig. Available in a practical range of sizes from 10 grams to 150 grams, it provides versatile options for beach casting, boat fishing, and targeting various species in different tidal conditions. The product is supplied as a single unit, ready to be integrated into your preferred fishing setup.
Features and Construction

The sinker's design focuses on functional performance for saltwater environments. Its construction directly influences how it behaves in the water column and during the cast.
Material and Build
The primary material is electrolytic lead, chosen for its high density and weight, which is essential for anchoring your bait in currents and achieving distance. The outer shell is cast around a pre-formed plastic core using injection moulding techniques, creating a single, integrated unit. This plastic core alters the overall density of the sinker compared to a solid lead piece, which can affect its sink rate and how it sits on the seabed.
Size and Practical Fit
The product is offered in twelve specific weights: 10g, 20g, 30g, 40g, 50g, 60g, 70g, 80g, 90g, 100g, 120g, and 150g. This wide selection allows anglers to match the sinker precisely to the fishing scenario, whether using light tackle for flounder in shallow water or heavier gear for cod in deep, strong tides. The olive, or elongated egg, shape with its textured scale surface helps it grip the seabed better than a smooth sinker, reducing drift.
Uses and Placement

This sinker is suited to various sea fishing techniques where a streamlined, fixed weight is beneficial. Its design lends itself to specific applications over others.
Event or Professional Use
For match fishing or commercial boat trips where precise bait presentation is critical, the consistent weight and shape of these sinkers allow for reliable rig behaviour. Anglers can standardise their setups knowing the 40g sinker will perform identically each time. The plastic core can offer a slightly slower sink rate, which is sometimes desirable when fishing over clean ground to allow fish more time to see the bait.
Everyday Home Use
For the recreational shore or pier angler, the range of sizes means one pack can cover multiple fishing sessions for different species. A 60g or 80g sinker might be ideal for general beach casting for plaice or dabs, while the lighter 20g or 30g options could be used for float fishing or light ledgering in harbours. The olive shape is less prone to snagging on rocky ground than pyramid sinkers, making it a good all-round choice for mixed marks.
Benefits and Buying Value

The value of this fishing sinker lies in its specialised design features and the practical coverage offered by its size range, providing a tool that can be adapted to many sea fishing situations.
Reuse and Low Maintenance
Lead sinkers are inherently durable and can be reused countless times if retrieved. They require no maintenance beyond rinsing with fresh water after use to remove salt, which helps prevent corrosion. The plastic core is sealed within the lead, so it won't degrade or waterlog with repeated use, ensuring consistent performance.
Why Choose This Product
Choose this sinker for its specific combination of a tongxin scale texture, rugby shape, and plastic core construction. This design aims to offer a balance of casting efficiency, seabed hold, and controlled descent. The comprehensive weight range means you can select the exact grammage needed for your rod's casting rating and the day's conditions, avoiding the compromise of using a slightly too heavy or too light sinker from a more limited selection.
