Sinkers will never be the most exciting item in your tackle bag, but they are essential to most forms of fishing.
Which sinker you choose will change with the style of fishing you are doing and what you are looking to achieve with the weight.
For shore-based fishermen, the sinker is a means of getting baits out a very long way and specifically designed casting sinkers help do this.
Specialist beach and shore casting sinkers feature wire arms which can grip very firmly in sand and will hold a bait in position in very strong currents and surf. When a fish bites these sinkers wires will break out and fold away to release from the sand.
