Use this to make sure that your electric fence is working properly. Easy to use. Just put the spike in the ground next to the fence and touch the top of the tester to the wire. The lights will flash to let you know how strong the current is. Somewhat hard to read in bright light, so best to use in a shady spot or on an overcast day.

Pros: Compact

Cons: Dim Lights

I love this tester over all testers I have had. It is accurate, durable and easy to use. Very reliable product.

Pros: Accurate, durable

Cons: None

Sure beats grabbing the fence!!! Ha, ha.
We have one and it is very handy.

Pros: handy

Cons: easy to misplace :)
