They're very readable in Zone 7a at dusk. The probe is solid. The hook makes it easy to hang on a high tensile fence, stick the probe in moist soil and read the results. Review: Works perfectly - This fence tester works really well giving the user an accurate measure of how powerful their fence is. Yes the lights are not bright enough to see in bright sunlight, but if you simply cover it with your hat or a piece of cardboard or aper, you can see is easily. When its cloudy or early or late in the day, the lights are very bright and easily seen and interpreted. The cord to the ground electrode is long enough to test the top wire on almost any fence. I am totally happy with this tester and see no real reason to spend more money on anything else. Buy and use with confidence. ## Features - Widely Application: The electric fence tester can only be used to test standard duty, low impedance electric fences.

It uses neon bulbs, not LEDs to show voltage, neons are durable and can handle thousands of volts, much easier to read in shade or in evening light. - Dim Lights And Neon Principle: The electric fence testers have a pulse low voltage wire fence, make sure the wires are not touching anything metal by using plastic insulation to attach wires to your fence posts. The tester does not use batteries, and thus works on the principle of the fence high voltage exciting a neon bulb. As such, the light will never be bright, due to the technology of the bulbs.
