  1. The Surge Three-in-One Transformer
  2. The Surge Mercury Safety Switch
  3. The Surge Fence Tester
    It may seem a presumptuous thing to say but is nevertheless a fact that the Surge Fencer is the only controller on the market that complies with all legal restrictions as to amperage and at the same time is so fully adjustable that an adequate STING is sent out onto the line under all conditions. Surge is the only fence controller that can start out with the legal 25 milliamperes and successfully maintain that amperage at the end of the line under normal, dry and very dry weather and soil conditions.

    This is not just a wild statement but something that is readily and easily proved with simple instruments. The Surge Three-in-One Transformer (patents pending) gives you:
  1. 750 volts for a 25 milliampere shock to hold cattle effectively under normal weather and soil conditions.
  2. 1000 volts for a 25 milliampere shock to hold cattle when the dry soil offers resistance.
  3. 1500 volts for a 25 milliampere shock when the dry, dusty earth resists the free flow of electricity.
    We use 750, 1000 and 1500 volts because both arithmetic and experience indicate that these voltages cover the most practical range and they are, therefore, widely accepted. Now let's take these same voltages and see what they do with the conventional transformer.... what they do with any transformer that we anything about:-
750 volts with a 25 milliampere shock does deliver an effective sting under NORMAL conditions.

Step this up to 1000 volts and the milliampere shock SHRINKS to 19 milliamperes.

Step it up again to 1500 volts and the shock shrinks to 12.5 milliamperes.
    So far as we can learn, that is a fairly exact picture of the performance of all other electric fence controllers because repeated readings persistently show that as the voltage goes up, the amperage does down.... and.... in proportion as the STING drops below 25 milliamperes, the effectiveness of the fence has to drop. When you turn the selector switch on the Surge Fencer from "Normal" to "Dry" to "Very Dry", you naturally increase the pressure or force and you do send the same 25 milliamperes out onto the line.

    That is made possible by the Surge Three-in-One Transformer--a thing that nobody else has and upon which we expect broad protection. It would be possible but certainly not good, to start out with a very high voltage and try to maintain that high voltage at all times and under all conditions and this to hold the amperage up to where it belongs.... or.... it would be possible to do what the Surge does--to be adjustable the way the Surge IS--by the use of THREE separate transformers. That could be done and some day it MIGHT be done but so far it HAS NOT been done and that's why we can say that the SURGE is the only fencer now being manufactured that can meet all legal safeguards and at the same time retain the FULL ADJUSTABILITY that means efficient performance under all climate and soil conditions.

    And now for the SWITCH. In terms of electricity, a SWITCH is something that turns the current on and off. The Surge Fencer is of the intermittent type designed for use on high lines. That means that in order to meet legal requirements, it must have a switch that will turn the current on for exactly the right length of time, turn it off, then turn it on again. It must do this automatically and unfailingly. It can't be something that will work nearly all the time or under certain conditions. It must never fail at any time nor under any conditions.

    So.... we have the Surge Mercury Safety Switch. In principle this consists of a globule of mercury encased in a small gas filled tube. Two electrodes enter this sealed glass case and as the mercury flows past these two points, contact is made and the current is on. The only way to have a continuous current would be to BALANCE the mercury in contact with the two points and that is something JUST CANNOT BE DONE. The two electrodes are shielded with glass so that even is the controller is upside down there can be no connection and therefore no outgoing current.

    This tube is in plain sight but is protected by a heavy plate glass; short of willful destruction, nothing can happen to it.... but.... if it is broken the current is off.

    The Surge Mercury Safety Switch has to be just as dependable and fool proof as the law of gravity.... so.... once more we say that this is something that the Surge Fencer does have that no other controller possesses. And once more we say that this is something that some of the others MAY have some day but do not have now.... some day somebody may think up some ingenious way to do what the Surge is doing NOW.... but.... because of the patent situation, it will have to be some other way.

    Practically all electric fence controllers provide an Indicator lamp of some sort and this is supposed to show the condition of the fence.... theoretically, a lamp does show the condition but in actual practice it tells so little as to be nearly useless. That is why many of the better fencers have some sort of an indicator or TESTER in addition to the lamp.

    For the most part these TESTERS indicate milliamperes going out onto the fence line.... so.... if there is a complete short, the indicator shows it definitely and accurately.... but.... under certain conditions almost sure to be encountered, the ammeter type of tester will show that there is no shock on the fence when, as a matter of fact, the fence is in good condition. When the fence is not working, an ammeter type of tester will not fail to show it, but it rings too many false alarms.... too often it sends its owner on a wild goose chase in search of a short that does not exist.

    The Surge Tester indicates the VOLTAGE on the fence line and there can be no false alarm about it. It tells so anybody can understand it whether the fence is in perfect shape, and if it isn't quite right, it shows just how serious the trouble out on the line is. The Surge Tester is so unique, so accurate and essentially right that here again we expect to obtain broad patent coverage.

    The Three-on-One Transformer; the Mercury Safety Switch; the Fence Tester at the present time belong to SURGE alone. ONLY the SURGE Electric Fencer can send an effective STING out onto the line and NEVER send out a current that is dangerous. Competent authorities have ruled that more than 25 milliamperes is unsafe.... experience has proved that very much less than 25 milliamperes is ineffective in the control of livestock.... so.... to be RIGHT an Electric Fence Controller has to hold the amperage within narrow limits.

    We believe that the real demand is for a fencer that will control livestock under any and all weather and soil conditions and only the Surge Electric Fencer can do that.... only the Surge can adjust voltages to carry the same legal and SAFE amperage all the way to the end of the line.
