New Electric Fencer Requires No Insulators

New Electric Fencer Requires No Insulators FENCING Tools 3-4-31 New from Baker Enterprises is the Bee Fencer that "makes old fence work like new-without insulators." The Bee will charge fencing stapled directly to wooden posts, according to Gary Boswell, engineer for Baker Enterprises, Edmondton, Alberta, Canada. It's available in a power-line model which plugs into a regular 110-volt outlet, a 12-volt battery model, and a special model for controlling coyotes and other predators. "All three models produce a regulated, high current pulse of very short duration. Weed burner type fence controllers, on the other hand, use a low current for long period of time," explains Boswell. "A high current pulse overcomes losses due to posts, grass, weeds and brush, and the short pulse duration prevents the controller from causing grass fires or being electrically hazardous." Baker Enterprises recommends that barbed wire be used with the Bee. "Smooth wire witout barbs, such as old telephone wire, isn't recommended because thickness of animal's fur insulates the animal from the shock. Barbs will penetrate the fur, making contact with the animal's skin," says Boswell. "The range of the Bee fencer is limited to how well the ground can return the current. In order for an animal to feel a shock, current must go through the fence wire, through the animal and back through the ground or ground wire. Thus, a single charged wire will work will only where the ground is a good electrical conductor," Boswell points out. Price of the power-line charged Model 7721, and the 12-volt battery operated 7722 (a rechargable automotive battery is recommended), is $99. Each unit will handle a quarter section of 3-wire fence. The model 7724, for predator control, sells for $135 and will charge a mile of single strand fencing. Baker Enterprises also offers a Fence Matching Transformer. The transformer is designed to increase effective fence voltage, and to decrease the maximum current available to the fence. The greater the fence voltage, the more effective the fence will be in poor ground conditions for control of predators and for control of sheep or other animals with thick fur. Price of the transformer is $30. For more details, contact: FARM SHOW Followup, Baker Engineering Enterprises, Box 8340, Station F, Edmundton, Alberta, Canada T6H 4W6 (ph. 403 465-5884).
