1 - What is GT200 Remote Substance Detection System?
GT200 Remote Substance Detection system is a revolutionary tool that provides you with 360° security protection. It is developed by Global Technical UK. The system has been developed to allow the search of large areas and reduce them to small locations . The GT200 allows for all types of narcotics or explosives to be searched for in one operation. Put it simply, it's Remote. Distance. Speed. Covert.
The GT200 should be used as first indication only, and conventional methods should always be used to confirm the result of the lock. By definition, a 'lock' means a triangulated position. It can be used as confirmation of suspicions. The GT200 saves the search team and canine's working time for more efficient working. When the GT200 is used by a canine team, the area of search can be indicated from a greater distance than the dog can smell, so putting the dog in the right area quickly. This ensures that the dog is sent in to more specific area, thus saving it from sniffing fruitlessly in unproductive areas.
GT200 was developed to meet the requirement of being able to detect a specific substance remotely from a safe distance. Detection devices in existence today are limited to the detection of substances from molecules at a very close range (less than 3 meters) such as IMS Technology.
IMS technology includes equipment such as Barringer, GE Ton track and Saber type detectors seen today at most airport facilities. The limitation of this type of equipment is due to the fact that actual physical contact analysis of a substance or group of substances must be made vapor or substance level.
However, the GT200 is designed to detect these same substances without having physical contact with the actual substance. By doing so, it is able to detect programmed substances at very long range safely, quickly and covertly. Building upon years of field testing and trials, the GT200 went through various hardware and software revisions into the unit that exists today.
Its target market is; Law Enforcement, Military Agencies, and the corporate entities that need the ability to safely identify the possible existence of a substance and identify the parameters of the area where that substance exists. Building searches, Road blocks, Airport Cargo Containers, building entry points, car parks, etc. are all areas for which the GT200 can be deployed effectively.
The GT200 works on the principal of dia/para magnetism. All substances carry a magnetic charge that, when stimulated by an impulse of electricity, (static) creates an attraction between the substance being detected and the GT200 unit itself. This is called EMA or Electro Magnetic Attraction.
The simple way to explain this technology is to take an inflated balloon and rub it on your hair. A static charge is being created making that balloon "attract" it to say, a wall. Provided that there is enough charge on that balloon, it will remain "attracted" to the wall for an indefinite amount of time. However, once the "charge" has dissipated, the balloon will then "unattached" between itself and fall to the ground.
What the GT200 is doing is creating an "attraction" between itself and the substance it wants to detect. Through the Substance Sensor Card and the movement of an operator, an attracting field is created in the card reader that, in turn causes the Receiver"s antenna of the GT200 to lock onto a signal, indicating the direction in which the substance can be located. When the magnetic signal of the substance that the GT200 is searching for, is located within its detection range, the GT200 receiving antenna will move toward the direction that the substance exist. In essence the GT200 functions like a hyper sensitive receiver.
No, the GT200 is NOT a pin-point detection device. It is designed to
- Identify the existence of the target substance(s) and
- Define the close-in search area to approximately 4 cubic meters. After the GT200 identifies the existence of the substance, it is up to the trained operator to use other search techniques to identify the exact location of the target substance.
Yes. Global Technical has produced a wide variety of Substance Sensor Cards for the detection of narcotics and explosives. This list continues to grow as more and more different types of narcotics and explosives are manufactured and distributed. In our standard GT200 kit, we include substance recognition cards to the client"s choice.
This generally meets most requirements of our clients. However there are times when specific clients either require more detection cards, or have identified other substances not generally used in normal day to day operation.
To date, we have not found anything that will totally block or stop the substance signal being detected. As with any equipment, there are limitations as to its use and for that matter, the GT200 has some guidelines for its use. Provided these guides (together with your operators training), are followed, you will have an effective tool enabling you to productively narrow down the area of search allowing other search methods to be deployed in the successful detection of the searched substance. Used correctly, the GT200 can detect substance(s) through walls, (even lead-lined and metal ones), water, (fresh and salted), fresh and frozen food, (fish, fruit, tea, coffee, ice), vacuum flask, containers, petrol and diesel fuel and even buried in the earth.
Yes. It is imperative that our training program be purchased with this unit as it will take, about 3 days to fully train an operative in the effective use of GT200. This does not mean that you will not be able to use the GT200 but in our training program, we aim to make you competent in the use of the product and to understand the readings you will obtain during normal day-today operational use.
The GT200 is no different than any other instrument that requires a human to operate. For example, just because you have read about golfing and have all the equipment does not mean that you can tee-off accurately! You can try, but without training you may have some degree of success or failure. The reality of the matter is that, without proper training you may find that the equipment does not appear to produce the results that you anticipated and therefore you can incorrectly judge the effectiveness of the equipment.
In the same manner, anyone can read the operator manual and try to use the GT200 and you may, or may not, achieve some level of success (or failure). However, with proper training, the trained operator will reduce, significantly, the chances of incorrectly using the equipment and this will also increase their ability to effectively identify the target substance and location of that substance.
It is very possible to totally miss the target substance if you are too close. Remember that the GT200 is a long-range detector and operates by triangulating locks obtained from the perimeter scan of the defined search area. In other words, the scan of the area should allow for a minimum of 4-5 meters outside of the search area.
Since the GT200 has the ability to detect substances from a very far distance, proper operational techniques must be used in conducting a vehicle road block search or when scanning an area where people are walking along a passageway. By sweeping a defined area in the path of travel (approximately 20-25 meters) and establishing a "clean area", it is very simple and effective to scan the clean area as vehicles enter that area.
By definition a "clean area" means that the background of the search area is not contaminated with the target substance. The GT200 will "lock" onto the first vehicles or persons that has the target substance. The GT200 antennae will stay and follow the target through the area for quick identification of any suspect substance being targeted.
Contamination is an important issue with regard to using GT200. It must be remembered that the GT200 unit has the ability to detect target substances at below trace level and therefore, even "shaking hands" can result in a person being detected using the GT200. However, with our intensive training program, we are able to show you how to avoid contamination issues and effectively eliminate any unwanted signals.
No. There are no harmful rays or emissions from the GT200. The unit is totally passive and is purely a receiver of information, NOT a transmitter.
Yes. The GT200 has the ability to detect substance either taken into, or hidden on, the body itself. Even users of narcotics drugs will be detected by the GT200. For example, a smoker of marijuana, who has recently smoked a marijuana cigarette, will be detected by the GT200. Users of cocaine and/ or heroin will also be detected, and depending on the quantity, a person/user, could be detected for up to 1 or 2 weeks! However, again, our intensive training program, we will show you how to deal with such scenarios.
The detection distance for general search is up to 700 meters. It can detect substances in water (fresh or salt) up to a depth of 850 meter. In the case of buried substance it can detect up to 60 meter deep. For aerial reconnaissance, the distance extends to 4 kilometers.
Yes. Weather can affect the GT200 performance, but not its operation. In a heavy downpour of rain, the GT200 will still operate but at a "reduced" operational distance. However, (again with training) we can demonstrate how best to operate the GT200 and how to avoid unnecessary environmental operating scenarios.
Electro-static electricity is very much misunderstood. The GT200 does not require power in order to operate. It requires a very high level of electric current but without amperage. This is why it cannot be mounted in a stationary position to operate. The production of power is generated by the movement of the operator. As the operator walks the perimeter of the defined search area, he (or she) is generating elector-static electricity. As one moves, you can generate power which, at times can be in excess of 2,500-3,000 volts! This in turns power the GT200. The GT200 becomes active and starts to receive signals from the magnetic signature of the targeted substance.
It is sometimes advisable to check people out, such as immigrants or "tourist" coming through a point of entry, prison visitors or even guards and prisoners in a halfway house. Search the line of people and where you have an indication isolate the people either side of your chosen target. Separate these people and re-check to confirm which one the GT200 has indicated on. Make sure you are at least 4 meters from the line. If you are too close it will be difficult to operate.
The GT200 will recognize the presence of drugs on or in the body, in cavities or even in the blood. Scanning the people in a line up should be undertaken with care. And the one or two suspected persons indicated by GT200 should be drawn aside and checked again. Great care must be taken not to accuse people, on solely the result of the GT200 lock. Standard conventional means should be used to verify the indication (e.g. urine test).
Although there is some suggestion of invasion of privacy, this is no worse than having a hand held metal detector swept over you, as used in clubs and shopping malls. Be aware that some medicines contain a base of illegal drugs, and if people are users, drugs will be indicated by the GT200, so tread carefully and gain all the facts first before relying solely on the GT200 in this instance.
False positives are problems in all known detection equipment in service today. Similarly, as with drug urine test, some suspects who are known to have taken medication with codeine may show positive results.
A manageable amount of false positives are generally incorporated into the continuing operation of detection equipment and can range from <1%>
Due to the nature of the technology upon which GT200 is built, it would be impossible for it to detect a substance that it is not programmed to detect. In other words, if the GT200 obtain a lock on an area for substance that the GT200 is searching for, and a "close-in" search using Canines or IMS portable equipment turns up nothing, it does not mean that the GT200 produced a false positive.
Explanation: The GT200 can detect to below the average <30>
Important: One important feature of GT200 is that, by detecting a contaminated area of a programmed substance, (for example, say, C4 explosives), one is alerted to the fact that, at some point in time, (whether recently or sometime ago), the item or area detected came in contact with that explosive. This could be extremely beneficial in scanning trucks and cargo containers. Since containers are normally closed when empty, they remain contaminated for some time and can be noted for tracing the origin of its cargo and routes.
In the case of Narcotics, Global Technical will train the operator to understand situations that may seem like an actual detection of a substance when, in fact, the detection may be produced by a substance that may contain a small portion of the programmed target substance. For example, many medicines today contain derivatives of Cocaine. When conducting a search of a passenger or baggage area at the airport, care must be taken to first;
- Determine the cause of the detection to determine whether it is from medications or actual substance first and
- Question the person, in the same manner as would be normally a suspect.
If possible wear cotton gloves or wash your hands. If you have to search a room, do it from the outside, it will prove much more successful. It is hard to make a sweep inside a room because of the furniture and other obstructions. Once the GT200 has indicated a specific area, enter the room, trying not to touch or sit on anything at all, have a colleague make the actual search, or send in the dog team. Then after it is removed, search the area again. The only problem now is the introduction of contamination by the search team and if a substance is found, be careful not to leave any residue behind.
The GT200 is currently in use by government, Military, Narcotics and Corporate agencies around the world. It is important to note that the GT200 is largely used as a covert equipment. Therefore our reference list remains confidential and not publish indiscreetly.
In selecting an area to search for your chosen target, be aware that there may be samples of the same product out there, not within in your search area. The GT200 will lock the first signal it aligns with, not necessarily the nearest or strongest. You can get unwanted signals, such as reading back to something you have touched or used, or reading a colleague you have touched, or has touched you, because you have not taken enough care with the elimination of contamination.
There are other things; trace elements of the substance you are seeking may be found on or in other objects. Some medicines contain drugs legally and can be detected. Nitroglycerine is an explosive and also used in heart medicines and can by pick up by our recognition signal for explosives. For these reasons it is important that all indications are put onto drawing of the area. Do not think that you will remember where they are; it is almost impossible. Take the point of the majority readings as your primary target search area and be prepared to accept the possibility of secondary areas. It is better to include secondary areas and search them than miss the substance.
The GT200 offers many operational cost potential savings. A few examples are offered here.
Mass Urine Test: Random mass screening may often yield low positive rates. Consequently, there may be potentially huge wastages of resources in terms of manpower and cost of test kits. Using GT200, you can narrow down to the most probable suspect(s) and eliminate these wastages.
Productivity: It is well known that surveillance can take a lot of effort in terms of time and manpower. Field intelligence can be misleading or inaccurate. Drug traffickers change their storage location frequently and have to be caught red handed. Using the GT200, you can potentially eliminate locations where there is no target substance(s) stored and re-deploy/prioritize your watch areas.
Bomb Threats: Bomb hoax incur cost each time by deploying search teams, evacuating and interrupting business operations. The GT200 can minimize these cost issues by sweeping large areas and narrowing potential location very quickly with minimum manpower and time
Manpower: A GT200 operative can scan wide areas and in a 360 degrees sweep than 5 o more security guards (depending on extend of the area).Effectively, you gain high productivity and you save significantly on manpower cost
Sounds too good to be true, doesn't it? That is probably because it still is too good to be true.
