Sea Fishing Rig Springs
For distance casting and just the reassurance that your bait is actually going to reach the fish (and not be flung off whilst casting) you need to secure baits during the cast. If you are using a lead link to secure your hooked baits, then you really should be using rig springs to ensure that the baited hook and trace moves away from the mainline when your rig hits the water, otherwise all you'll probably end up with is a tangled mess!
Rig springs have been developed over a number of years to eradicate the scenario outlined above, allowing maximum casting effort to be employed even with soft baits. Fabulous for the mainstay of distance casting rigs such as the Bomber, but equally good for any multi-hook rig for flatfish or Cod, rig springs enable multiple baits to be used without risk of mass tangles.
