The Gemi electric fence - 100% Made in Italy - is used to ward off wild animals such as wild boars, deer, foxes, etc.
The purpose of electric fences is to protect the territory from unsightly invasions. It is also used to contain animals such as cows, sheep, pigs etc.
It has nothing to do with hunting. We have all the legal certificates available to produce and sell electric fences. This is the only legal solution for those who want to protect their plantations.

Electric fence reels
An electric fence reel allows polywire, tape and rope to be wound, stored and deployed efficiently — an essential tool for rotational grazing systems where the fence position changes regularly. Gemi Elettronica supplies reels in designs matched to each conductor type: compact lightweight reels for 2.2 mm² and 4 mm² polywire, heavy-duty reels for 6 mm² wire and braided rope, and wide-spool models for 20 mm and 40 mm tape. Gemi electric fence reels are sold individually and in twin-packs for two-person deployment of long fence runs. Order direct from Gemi Elettronica for factory pricing and UK delivery in 24–48h, compatible with all conductor types in the current range.
Polywire reels
A polywire reel fitted with a conductor brake maintains tension as the wire is deployed, preventing the uncontrolled unwinding that tangles thin wire around posts and insulator clips. Gemi reels for polywire are designed to hold several hundred metres on the spool without increasing deployment friction as the spool diameter decreases — a common failing in cheaper reel designs that makes the last hundred metres of wire difficult to pay out under normal walking tension.
Tape reels
Electric fence tape reels use a wider spool to accommodate the flat tape without folding or kinking, which would crack the woven conducting filaments at the crease and increase electrical resistance at that point. The reel housing includes a braking mechanism that allows single-operator deployment: the tape pays out as the operator walks forward under the weight of the reel, maintaining consistent tension without a second person holding the reel.
Robust construction for regular use
Reels used in rotational grazing may be wound and unwound several times per month across the grazing season. Gemi reel bearings and braking mechanisms are rated for this frequency of use without deterioration of the braking function, which is the component most likely to wear on high-use reels.

Questions and Answers
The electric fence for animals is neither dangerous for people nor for animals. As with everything, even for electric fences there is a standard that establishes the values to be respected.
The fence energiser is a product that emits intermittent pulses with a low amperage.
To create an electric fence for animals you need: a Gemi energiser - 100% Made in Italy - for fences that carries the current to the fence, an electrified conductor wire for the fence and insulators for electrified fences screwed on the posts to hold the wire.
Grounding is a fundamental thing for the functionality of the electric fence for animals, so it is recommended to do it correctly. To have the total discharge of current by the energiser, it is necessary to make the grounding by inserting 3 galvanized poles of 1 meter in the ground.
They must be positioned 3 meters apart, 80 cm in the wet ground and 20 cm outside, and then connect them with the yellow cable.
Together with the electric fence, we supply only 1 meter of cable that must be connected to the first pole. It is recommended to do it where there is the presence of vegetation, therefore a moist soil. Arid soil is not conductive. According to the tests carried out, placing 3 poles in any type of terrain, there will be no problem with functionality.
If you put only one stake, the power of the current felt will be less than its range and the animals will be able to cross the fence.
For a B12 energiser it is sufficient to use a 12V 40Ah car battery. The autonomy, if there is no dispersion in the electric fence, is about 10/12 days. Otherwise it lasts less.
If the current is far from the electric fence, for your Gemi energiser - 100% Made in Italy -, we have the high-voltage crossing cable that can work on the surface or underground, without discharging.
With this cable it is possible to carry current on the fence, without any dispersion.
The cable for electric fences can also be used to join two fences, then connect one end to a first fence and the other end to a second fence, when there is little distance between one fence and another.
To check if there is current on the electric fence for animals, just bring the tip of a screwdriver with an insulated handle a few mm away from the fence wire.
The moment you hear a ticking, it means that there is current on the electric fence.
An energizer cannot be kept outdoors. It must be kept indoors to prevent damage from the weather. In order to discharge all its current, it must be earthed by inserting 3 galvanized 1 meter stakes into the ground. They must be placed 3 m apart, 80 cm in the ground (wet) and 20 cm outside, and then connected with the yellow-green cable.
The device has a red positive cable at its output which is connected to the fence and a yellow-green cable which is connected to the first ground stake.
Never connect two electrifiers to the same wire, as the two impulses may cancel each other out, causing problems. You can connect two electrifiers to the same fence, but keep them on two separate lines of wire.
