Tongxin Sinker sea fishing olive lead weight with scale, constructed from electrolytic lead in a rugby shape with internal plastic core, ideal for beach casting and general sea angling
Tongxin Rugby Olive Lead Fishing Sinker with Internal Plastic Core and Scale Markings

This Tongxin sinker is designed for anglers requiring a dependable weight for sea fishing scenarios, from beach casting to boat fishing. Its primary function is to anchor your bait presentation at the desired depth while maintaining stability against tides and currents. The product's construction focuses on practical performance, utilising electrolytic lead for density and a distinctive rugby shape with an internal plastic core to aid its flight through the air. A simple scale marking system allows for quick visual confirmation of the sinker's weight during tackle setup.
Features and Construction

The sinker combines fundamental materials and a specific shape to fulfil its role in a fishing rig. The design priorities are aerodynamic stability during the cast and reliable holding power once it reaches the seabed.
Material and Build
The sinker is moulded from electrolytic lead, a material chosen for its high density relative to its volume. This density is crucial for providing the downward force needed to counter buoyancy and water movement, ensuring the rig reaches the bottom and stays in the intended fishing zone. The internal plastic core is a fixed component of the moulding process, contributing to the final shape and potentially influencing the weight distribution within the sinker itself.
Size and Practical Fit
The product is categorised by its weight, which is its key practical specification. It is available in a comprehensive range from a light 10g option up to a substantial 150g weight. This allows anglers to match the sinker precisely to conditions: lighter weights for calm inshore waters or slow-sinking presentations, and heavier weights for strong tidal flows or deep-water marks. The exterior scale marking provides a clear, at-a-glance reference to confirm you have selected the correct weight from your tackle box.
Uses and Placement

This type of sinker is a versatile component in sea angling, suitable for various rigs and target species. Its application is defined by the need to present bait effectively on the sea floor or at a specific depth in the water column.
Event or Professional Use
For match fishing or sustained fishing sessions from piers, beaches, or rocks, having a consistent, reliable sinker is important. The uniform rugby shape and construction can help standardise casting distance and accuracy. The wide weight range means an angler can carry a single style of sinker to cover many different marks and tide states, simplifying gear preparation. The scale markings are particularly useful when changing weights frequently during a session to adapt to changing conditions.
Everyday Home Use
For the recreational sea angler, this sinker represents a straightforward, functional piece of terminal tackle. It is designed to do a specific job without unnecessary complexity. The rugby shape is a proven design that generally resists rolling in currents better than a plain ball sinker, helping to keep the bait in place. The availability of common weights like 4oz (approx. 113g) and 5oz (approx. 142g) within the range covers many standard UK beach fishing scenarios.
Benefits and Buying Value

The value of this fishing sinker lies in its focused design and the practical coverage offered by its weight range. It is a consumable item intended for repeated use until lost or worn.
Reuse and Low Maintenance
As a solid lead weight, it requires virtually no maintenance. After use, it should be rinsed in fresh water to remove salt and stored dry to prevent corrosion of any attached swivels or clips. Its durability is tied directly to the properties of lead; it may become dented or scratched with use, but this does not typically affect its primary function. It can be reused indefinitely as long as it remains attached to the line.
Why Choose This Product
This sinker offers a clear, practical specification centred on its weight and shape. The inclusion of the plastic core and scale markings are functional differentiators. For anglers seeking a no-fuss, effective weight for general sea fishing, the comprehensive weight range means you are likely to find the size you need. It provides a specific tool for the job, manufactured from the standard material for this application.
