Teknetics T2 is a multi-purpose high-performance computerized metal detector. When this detector was first released the price tag was $849 -- now it's only $499! It has the high sensitivity and ground cancellation features needed for professional gold prospecting, the discrimination responsiveness needed for serious relic hunting under difficult conditions, and visual Target-ID considered essential in searching for coins. The ground cancellation system can be adjusted to allow searching saltwater beaches.

This detector comes with an 11-inch elliptical Bi-Axial searchcoil for maximum detection depth in mineralized soils. An accessory bundle for the T2 includes a smaller coil, backpack, hat, and more is also available (additional charge). This machine is light weight and the best balanced of any high-performance metal detector, so you can hold and swing it almost effortlessly. The armrest position is adjustable to fit your arm. The grip is durable high-friction foam elastomer, comfortable in any kind of weather. The controls are conveniently located and easy to learn how to use. Locking collars on the tubes eliminate rattling. The entire menu is always visible on the LCD display. The LCD display indicates the electrical signature (Target-ID) of the detected metal object. The display provides continuous information on battery condition and on ground mineralization, which affects detection depth. Help messages are automatically displayed on the lower right corner of the display when necessary.

A great benefit of the Teknetics T2 is that it is easier to learn to use properly than other comparable metal detectors. A few of its best features inclue:

• Simple, easy-to-use controls
• Large LCD screen with target identification and operating control displays
• Straightforward menu-driven user interface
• Bar graph readout of ground mineral concentration
• Trigger-actuated FASTGRAB™ ground canceling with manual override
• Waterproof 11-inch open-frame BiAxial™ searchcoil
• Single-Filter All Metal Mode for maximum detection depth
• Double-Filter Discrimination Modes for searching in trashy areas
• Trigger-actuated target pinpointing with variable audio pitch

The T2 is powered by four AA alkaline batteries, which will typically last for more than 40 hours of use before needing replacement. The lead engineers on the design team were John Gardiner, firmware engineer, and David Johnson, whose expertise is behind many of the best-known high-performance metal detectors offered by major U.S. manufacturers for the last 26 years. 5 year manufacturer warranty from First Texas Products, LLC.

Most metal detectors, like the Teknetics T2, use VLF Induction Balance technology. Here’s how it works: The searchcoil (also called search head or loop) contains two electrical induction coils which are like antennas. One coil transmits a rapidly alternating magnetic field, illuminating the region surrounding the searchcoil. If metal is present, its electrical conductivity distorts the magnetic field. If iron metal is present, its magnetism also distorts the magnetic field, but in a different way, allowing the metal detector to distinguish between ferrous and nonferrous metals. The other coil is a receiving antenna which detects changes in the magnetic field caused by the presence of metal. Electronic circuits amplify this weak signal, analyze it to determine the changes which occur as the searchcoil sweeps over the target, and then convey the information to the user in the form of a visual display or audio tones. Most modern metal detectors perform many of these tasks in software running on an internal microcomputer. The iron minerals which are present in most soils also distort the magnetic field, obscuring the weak signals of small or deep objects. This can cause the object to go undetected, or to be misidentified when it is detected. Much of the technology that goes into modern metal detectors is devoted to the task of eliminating the unwanted signals from iron minerals in the soil, while not losing the signals from metal objects.
