Quick Buying Tip
Don’t skimp on the Joules. A “10-mile” rating assumes a single wire with zero weeds. If you have a multi-wire fence or heavy vegetation (weeds touching the wire), cut that rating in half or buy a unit with higher Joules (0.25J+) to ensure the shock actually reaches the end of the line.
