Tongxin scale sinker sea fishing explosive hook plastic core olive lead weight 10g to 150g range rugby shape electrolytic lead construction for casting and bottom fishing
Tongxin Scale Olive Lead Sinker with Plastic Core for Sea and Explosive Hook Fishing

Designed for anglers targeting species in sea environments, this olive lead sinker provides the essential weight needed for casting distance and maintaining bottom contact. Its construction from electrolytic lead ensures a compact, dense form factor, while the unique rugby shape, achieved through inner core injection moulding, offers a balance of aerodynamics for the cast and stability on the seabed. Available across a comprehensive range from 10g to 150g, it allows for precise weight matching to current strength, depth, and bait presentation requirements for explosive hook or standard bottom fishing techniques.
Features and Construction

The sinker's primary design focuses on delivering reliable performance in saltwater fishing scenarios. Its build and shape are intended to address the practical needs of casting and holding position, utilizing materials chosen for their functional properties in this context.
Material and Build
The sinker is fabricated from electrolytic lead, a material selected for its high specific gravity, which allows a smaller physical size for a given weight, reducing water resistance. The manufacturing process involves inner core injection moulding, which forms the distinctive rugby shape and integrates the stated plastic core within the lead shell. This method creates a cohesive unit with the textured, scaled surface that characterises the olive pendant design.
Size and Practical Fit
The product's utility is defined by its available weight spectrum. With options spanning from a light 10g up to a substantial 150g, it covers a wide array of sea fishing situations. Anglers can choose a 30g or 40g weight for calmer inshore waters, progress to 70g or 80g for moderate currents, and select 120g or 150g for deeper marks or stronger tidal flows. This range facilitates precise tackle tuning without needing to switch to a completely different sinker type.
Uses and Placement

This sinker is suited to specific fishing methodologies where weight and bottom presentation are critical. Its design considerations make it applicable for both dedicated techniques and adaptable everyday use.
Event or Professional Use
The sinker is explicitly indicated for sea fishing and for use with "explosive hook" setups—a term often associated with certain European sea fishing rigs designed for casting distance and specific bait presentation. The rugby shape and weight range make it suitable for competitive shore fishing or professional guiding scenarios where consistent casting and reliable holding power are measured requirements. The scaled texture may also aid in grip on sandy or muddy bottoms.
Everyday Home Use
For the recreational sea angler, this sinker serves as a versatile component for general bottom fishing rigs from beach, rock, or pier. The olive shape and plastic core construction aim to provide a cost-effective, single-unit sinker that is easy to tie into a standard paternoster or running ledger. Having a selection of weights within the same product line simplifies gear preparation for varying trip conditions.
Benefits and Buying Value

The value of this fishing weight lies in its focused design and the practical advantages derived from its stated specifications. It offers a solution built around specific angling needs rather than generic features.
Reuse and Low Maintenance
As a solid lead and plastic item, the sinker is inherently durable for repeated use. After fishing, it can be rinsed with fresh water to remove salt and debris, then stored dry. Its simple construction means there are no moving parts to fail or fabrics to degrade, offering long-term usability as part of an angler's terminal tackle selection, provided it is not lost to snags.
Why Choose This Product
This sinker provides a specialised tool for sea anglers who prioritise a specific weight profile and shape. The key decision points are the need for a rugby-shaped olive sinker, the requirement for a weight within the 10g-150g spectrum, and the preference for a product with an internal plastic core made via injection moulding. It represents a direct match for those seeking these particular attributes for their fishing rigs, as confirmed by the product's own description.
