Electric Fencing Supplies
Excerpted from the website:
- Our association with Electric fencing began twenty years ago in central Africa operating out of Zimbabwe (formally Rhodesia) where we used electric fencing to assist farmers, wildlife conversationalists and entrepreneurs to control the African wildlife. This involved a huge range of animals from Elephant down to the common rabbit. One particularly satisfying project was assisting to secure the safety of the declining Black Rhino population in Wildlife conservancies.
