handheld LASER voltage tester for electric fence? Answered

Is there such a device where i can detect voltage along an electric fence keeping out wild elephants WITHOUT having to get off from the truck and personally testing the fence? Is there such a device where I can simply point my handheld device using laser or anything from the safety of my truck|?
Walking through the bush and jungles are also pretty handful...
Im looking @ a distance of about 10m to 20m gap between my truck and the fence.
Any advices please email me directly - jungletrekker69@gmail.com
Or comment in this excellent forum?

Can you please tell us what is the fence made up of ? Give us a description. I know only how regular cattle electric fences are made. Hand held laser voltage tester .I nerver heard of such kind of device , may be you are inspired by IR hand held remote teperature testers. I don't think that a reflected laser beam can give informations about voltage of the surface because the surface should be changed in its relectivity to laser some color light by electric voltage. That would be a very nice phenomena but i don't think that common materials have such a peculiar property in a non extreme voltage. May be in some kind of situation it could be possible to detectct air jonization close to the fence but in this case thousands volts voltages are needed. In this case you actually can feel a sort of wind blowing from the conductor and this could give some optic difraction possibly detectable whith a laser device in air very next to the fence. But in this case voltage is a derived paramenter not directely measured. Such jonized wind is much more apreciable if the conductor has a prong shape, but I don't think is this case of the fence you are dealing with.

Its just a normal fence like any other common electric fence - the idea is just to know of there is voltage running of about 6-9v...just enough to give any wildlife a slight jolt without harming them.
We just hope that no one teaches the elephants that electricity doe not flow on ivory!!!!
We do maintenance of the vegetation parallel to the fence so that it would be easy for us to walk towards the fence.
Using IR is also good - Im not an electronic nor an electricity related expert - Im just trying to find out the most easiet and hassle way to know if there is there is an voltage flow of electricity along the fence.
We could divide the length of the voltage flow into several smaller compartments like one compartment with 4 km, put a pole with LED lights high enough to tower above bushes.
Or a flat area where we can just point the handheld device to the shorter poles and check if there is a voltage flow flowing through.

A quick online search shows that fences run 700- 10,000 v It may be SUPPLIED by a low voltage battery, but then the voltage is raised by a transformer. 6-9 volts won't even be felt unless one puts their tongue on it.

There are several types of electric fence testers.  One type has one or more lights (I suspect neon bulbs) that light up to show the fence is working. You may be able to 'permanently' install several of them at increments along the fence and then check the status indicator from a distance with binoculars.  The only concern is If the tester puts too much load on the fence (multiple testers on at the same time use too much of the fence charge and make the fence inoperative).

Here is an example of one of the testers:

Good Luck!

Lasers? No.

How far is it from truck to wire?

Either I'm going blind, or he edited that... Probably the former.
