Sea fishing olive lead sinker with scale and Tongxin plastic core available in rugby shapes from 10g to 150g for bottom fishing tackle and lure rigs, an electrolytic lead core weight with inner moulding for castable rigs.
Scaled Tongxin Plastic Core Olive Lead Sinker for Sea and Bottom Fishing

This olive lead sinker combines a functional rugby shape with practical internal construction for anglers targeting sea and bottom fish. Designed to be castable and stable, it integrates a Tongxin plastic core, which acts as a ready-made attachment point for creating various rigs. Available across a spectrum of eleven precise weights, from a light 10g option suitable for estuaries up to a substantial 150g weight for deeper water or stronger currents, it allows precise tackle matching. The scaled texture on its surface is a specific design feature intended to influence bait presentation and movement in the water.
Features and Construction

The sinker's design focuses on practical performance elements for fishing tackle. Its rugby shape and internal plastic core are its key construction features.
Material and Build
The sinker is constructed from electrolytic lead, a material chosen for its density and suitability as a casting weight. The manufacturing process involves inner core injection moulding, which encases the Tongxin plastic core within the lead body. This creates a secure, integrated structure where the plastic element is firmly held, providing a reliable point for line attachment or additional rig components without compromising the weight's integrity.
Size and Practical Fit
Available in a comprehensive range of weights, the sinker provides options from 10g to 150g. This allows anglers to select the exact weight needed for their rod's casting rating, the depth of water, and the strength of the tide or current. The rugby shape contributes to its stability during the cast and its descent through the water, potentially reducing line twist compared to some other sinker profiles.
Uses and Placement

This product is tailored for specific fishing techniques where a led weight is a fundamental part of the setup. Its design supports both common and specialised rigs.
Event or Professional Use
For competitive sea angling or commercial fishing scenarios where terminal tackle reliability is critical, the secure inner moulding and specific weight gradations allow for precise setup replication. The plastic core can be utilised to quickly construct pulley, ledger, or running rigs, saving time when changing setups between marks or in response to changing conditions.
Everyday Home Use
For the recreational angler, this sinker simplifies rig creation. The built-in plastic core means there is no need to separately source or attach a swivel or bead for certain rig types; the connection point is already part of the weight. The scaled finish may help animate bait more naturally on the seabed, which can be an advantage when targeting species like cod, bass, or flatfish.
Benefits and Buying Value

The value of this sinker lies in its combination of specific design features aimed at solving practical fishing problems.
Reuse and Low Maintenance
As a solid lead weight, the sinker is inherently reusable and requires virtually no maintenance beyond rinsing after use in saltwater. Its robust construction means it is not prone to breakdown from water exposure, barring physical damage from snags. The plastic core is protected within the lead body, shielding it from direct abrasion against rocks or debris.
Why Choose This Product
This sinker offers a distinct combination: a traditional dense lead weight with a modern, integrated rigging aid. The Tongxin plastic core differentiates it from plain lead weights, adding functionality. The wide weight range in a single product line means an angler can standardise their tackle with one sinker type across many different fishing situations, from light lure fishing to heavy ground bottom fishing.
