Maybe so. The 2.4' spike those tiny chargers cane with didn't work well in dry areas. In my case, I had the fence with a very low bottom row. Sheep/goat on two rolls and poultry on another. That made it just about worthless on grass over a couple inches tall. Been using 4 stands of poly wire lately with mixed success. Easier to run anyway.
Gallagher B200's are nice. Put a smaller battery and it isn't too bad. Lost one of two (maybe) over 6-7 years. Premier's .5 joule smart charger died much faster, in part due to the stupid plastic panel face.
What speedright do you have? I need a replacement.
