Thomas Afilani is a well known adventurer, traveler, treasure hunter and most of all an accomplished and talented inventor. As an avid treasure hunter, he realized early on that in order to be successful in this field he needed to locate precious metal from a distance, so as to increase vastily his search area in the minimum possible time, something metal detectors could not do. His research and experimentations took years, but eventually he developed some promising prototypes, which climaxed the founding of the Electroscope Company in the mid 1980's which is now the undisputed leader in the long range technology field.
    Today Electroscope offers a wide selection of long range instruments which not only locate treasure from a distance, but have the added ability to lead you to the spot, usually pinpointing it within a 2-4 foot square. Electroscope models are free floating on the handle(except the gravitator which has a free floating antenna pod only) allowing the instrument to turn and point in the direction of the detected target and lock on to it. A good example to visualize this is how the needle of a compass always points to true North regardless of how the compass is turned. Once a lock is achieved, the instrument has the ability to bring you to the target by means of either the boxing or triangulation method.
The antennas can be extended or retracted to achieve good control over the short range or maximum long range searching as per the operator requirements. This also allows the operator to take an educated guess as to target distance according to the length the antennas are extended to.
    All Electroscope models can achieve depths from 15 to 30 feet deep on large targets, 6 to 12 feet on medium targets, and surface up to 2 to 4 feet on small targets. Distances from targets are usually from a quarter mile plus depending on such factors as ground minerals, target size, length of time target was in the ground, type of container as well as other factors like operators experience. Freshly buried targets give off weak signals, while targets buried a long time will produce much stronger signals as a result of the chemical reaction which takes place naturally between the target and the ground matrix.
