Vortex (fishing)
In the field of fishing , vertebrae form an important part of the equipment of a fishing rod . They are usually used as a link between the main line and the leader .
function
Most vertebrae have a rotatable bearing and are provided with an eyelet (line side) to attach the fishing line at one end and a snap hook to attach the leader to the other . The fishing line is fixed to the eyelet with the help of a knot . The leader can usually simply be hung in, as it usually already has a loop for this purpose. The vortex prevents the fish from twisting the fishing line while it is being hauled in after the bite by twisting itself around multiple times. This also prevents twisting due to twisting bait (e.g. earthworm).
execution
There are different types of vertebrae, each tailored to the respective fishing method or target fish. They usually differ in size and stability (or load-bearing capacity), but there are also different designs. For example, there are special ocean eddies to withstand the loads that occur there. Other special designs are ball-bearing swivels, in contrast to the otherwise common bearing with a simple axis of rotation. Double swivels have a snap hook on both sides instead of an eyelet and only one snap hook. Vortices are mostly made of metal , for example brass or various other alloys are used here.
Others
Vertebrae are available from the fishing store. Different knots are used to connect the main line to the eyelet of the vertebra, for example clinch , grinner and trilene knots .
