How to choose right electric Fence Tester

What to look for in an ideal fence tester? A buyer has to make sure everything is in order for his animals’ safety. Here is what you should look for in a fence tester

Fence Tester Types

There are plenty of electric fence testers available in the market, buy the one as per your requirements. If it is just for monitoring the fence working, go for a little key, or a metal thing. However, if you want them to serve a greater purpose, buy the digital testing machines.

Accurate Voltage Values

Measuring accurate voltage values is the primary purpose of a tester, if it fails to deliver, what’s the good in buying such a tester. Look for the one that detects shorts and points toward the direction where there may the fault is.


We would recommend the LCD screen display as this feature provides accurate and exact voltage values. A large, backlit LCD screen allows you to read voltage levels at any time of the day and night.


Every voltmeter has a different way of notifying about the fence functionality. They indicate fence working condition with a tone, the flashing signal lights, or beep.


Most fence testers come with a replaceable battery and a limited lifespan. Select a high-powered battery device to save you the trouble of changing batteries frequently.

Robust Case 

The rugged, tough case must be made of high-quality material to be weather resistant. It has the ability to resist shock as well as water. 


Choose a fence line tester keeping in mind the frequency of use and size of the fence. A pocket-sized tester would be convenient to carry around. However, a tester too small in size would be difficult to handle during the testing.

Lastly, we have presented you a list of some reliable electric fence line testers, now, choose from them as per your requirement. However, we would recommend going for digital testers if you want accurate measurements.
