Instructions

*The actual acres or kilometres of fence powered by this Energizer depends on your farm electric fence conditions and therefore varies greatly. The best method to compare Energizers is to use pulse output energy (Joules).
**For connection from the Energiser live terminal to the fence you will need a suitable high voltage cable (not included).

***Battery not included.
