Customer Reviews
I was looking for an electric fence energiser for cattle field fencing and didn't want to pay Gallagher prices. This 3.5 joule unit is brilliant. Pushes 8kV through the line even with a bit of wet grass touching it.
Excellent 12v electric fence unit. We use it off-grid on a 12V leisure battery for our highland ponies. The pulse is strong and the LED indicator is very handy for checking it from a distance.
Bought this mains electric fence energiser online after our old Rutland packed up. It arrived next day as promised. Very easy to mount in the barn and hook up to the main paddock. Highly recommended.
A very capable farm fence controller. Plenty of power for the sheep netting. My only slight gripe is that it doesn't come with an earth rod in the box, so I had to order one separately.
Without a doubt the best electric fence energiser I've used for the price. The dual power option is a lifesaver when we need to move the cattle to the summer grazing where there's no mains power.
Solid, well-built electric fencing power unit. It's currently running about 6km of high tensile wire for our dairy herd and hasn't missed a beat. Good value for money.
Perfect horse fence energiser! The weather-resistant casing is robust, and it survived the recent torrential rain without any issues. Gives a very sharp shock that keeps my cob off the timber rails.
