Gallagher Vidoflex 9 TurboLine Plus Blue 1000m 52% stronger than traditional polywire. Will not twist or kink when winding onto reels. Ideal for long portable fences, the patented mixed metal conductive wires carry the pulse 40 times better than standard PowerLine wire. Always use TurboLine products if fence > 500 m. UV- warranty: 5 years. The blue colour is particulary for wild animals, because they see the colour blue very well. This keeps them out of your field with your domestic animals or crops.
