Pos/Neg fences can be converted to Pos/Pos in moist conditions. This will deliver more pain to the animal than an all hot net (Pos/Pos) because moisture in the soil is not required to complete the circuit. In order to receive a shock, the animal must touch both a positive (hot) and negative (grounded) strand at the same time. A PowerLink must be purchased separately to make the secondary ground connection. Because half the strands are connected to the ground terminal or ground rod, reliance on soil moisture is reduced. To overcome this, Pos/Neg nets* are wired to allow the use of every other horizontal strand as an extension of the ground terminal. However, not all areas have the required moisture.ĭry soil increases resistance-a weaker, less effective pulse occurs that does not deter animals. × About Positive/Negative (Pos/Neg) Nets Is your area dry?Ĭonventional electrified fence systems rely on soil moisture to be effective. I can feel the substance in the hammer shifting to throw weight behind the blows. I wonder if they were trying to work in frigid temps with frozen soil and brittle plastic? Regardless, that's not my experience.
So I don't understand the several highly negative reviews here. With the hammer, the posts go in, inch by inch, and are very solid. But pushing the posts in by hand is far too hard even when I don't hit anything big. Shale is soft and brittle unless it's a ledge. Please understand, if I hit a rock I'll usually try to dodge it or use my cordless drill to make a pilot hole. Also, where I am working are many tree roots. We have had only three measurable rains since February-I am writing this in mid-May-and the heaviest rain was 3/4".

Our soil here is rocky clay, full of shale, and it is now very dry. This hammer has been helping me erect 10 rolls of 48" ElectroNet for a semi-permanent chicken range for some young chickens.
