The Vexed Dingle Dangle is used as a floatation core to build baits around in order to float them up off the bottom. Floating baits off the bottom does not only give the bait more presence, it also reduces stingray and crab interception. The dingle dangle concept was most probably started by pommie carp anglers, but surf modified and perfected by our mates "Back in South Africa". Dingle Dangles are best fished with a single circle hook via an English style, clipped down pulley rig to maximum floatation and cast ability. To build a bait really depends on the fish species you are targeting, but squid, pilchards and any fresh cut fish baits such as mullet or tailor can all be whipped into your desired shape around your Dingle Dangle.
Don't forget to use a good latex bait thread such as Vexed Fillet or Squid Thread.
