This aids in pinpointing the exact location of objects which were found while searching in the All Metal or Discrimination Mode. When the trigger is pushed forward, FASTGRAB automatic ground cancellation is activated. The internal computer measures the magnetic properties of the soil in order to cancel interference from naturally-occurring minerals in the ground.

  • Page 12: Ground Cancellation

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting GROUND CANCELLATION What is Ground Cancellation? All soils contain minerals. Signals from ground minerals are often tens or hundreds of times as strong as the signal from a buried metal object. The magnetism of iron minerals, found in nearly all soils, causes one type of interfering signal.
  • Page 13 TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting GROUND CANCELLATION (continued) MANUAL GROUND CANCELLATION In most situations, it is preferable to push the trigger switch to activate FASTGRAB automatic ground cancellation. Generally, it is best to first let the computer automatically cancel interference from ground minerals.

  • Page 15: All Metal Mode

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting ALL METAL MODE The All Metal mode is more sensitive and offers better feel than the Discrimination mode, and is used to find all metal objects present in the ground. The searchcoil must be in motion for objects to be detected.

  • Page 16: Discrimination Mode

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting DISCRIMINATION MODE The Discrimination Mode is used to eliminate from detection trash metal objects such as nails, aluminum foil, or pull-tabs. The searchcoil must be in motion for metal objects to be detected. Discrimination incurs some loss of sensitivity to small or deep objects.

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting DISCRIMINATION MODE (continued) 2+: Two tones. Similar to 1+, except that iron produces a low-pitched tone regardless signal strength. The discriminator is continuous. However, the iron tone feature relies on a combination of continuous and sampled processing.

  • Page 18: Pinpoint Feature

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting PinPoint Feature After a buried target has been located using the All Metal or Discrimination modes, you want to pinpoint the exact location of the target in order to facilitate its recovery. Accurate target pinpointing will minimize digging.

  • Page 19: Lcd Visual Display

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting LCD VISUAL DISPLAY In normal operation, when the searchcoil passes over a metal object, the electrical signature (2-digit I.D.) of the metal object is displayed on the numeric display for 4 seconds, unless superceded by another object sooner.

  • Page 20: Target Depth

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting LCD VISUAL DISPLAY (continued) The target indicator arrows are coded for signal strength — bold arrow for strong signals, caret ) arrow for medium signals, and small triangle for weak signals. When sweeping back and forth to check a target, the indications corresponding to the strongest signals will usually be the most accurate.

Magnetic susceptibility is expressed in terms of the percent volume of the iron mineral magnetite, which most black sand is made of.

  • Page 22: Capabilities & Limitations

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting CAPABILITIES AND LIMITATIONS DEPTH The T can detect U.S. coins to a depth of about 12-15 inches under good conditions. Large objects (55 gallon drums, manhole covers, etc.) can be detected to a depth of several feet. Electrical interference from power lines and from electrical appliances and electronic equipment can reduce detection depth, or cause audible interference, making it necessary for the user to reduce the sensitivity setting.

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting CAPABILITIES AND LIMITATIONS (continued) GROUND CANCELING To achieve maximum depth in both the ALL METAL and DISCRIMINATION modes, as well as when using the PinPoint feature, the T offers the ability to cancel ground minerals either by manual adjustment, or automatically using the FASTGRAB feature (see p.11).

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting CAPABILITIES AND LIMITATIONS (continued) STEEL BOTTLE CAPS & FLAT IRON TRASH Modern motion-type target ID metal detectors usually have difficulty consistently identifying steel bottle caps and other flat iron trash objects. Double-D searchcoils also have a reputation for being unable to distinguish steel bottle caps from coins, and for being unable to eliminate steel bottle caps from detection.

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting SEARCH TECHNIQUES Sweeping Searchcoil (this does not apply to Pinpointing with the trigger switch) Keep the searchcoil in motion to RIGHT detect targets. Sweep the searchcoil parallel to the ground; do not lift the searchcoil at the end of the sweep.

Now you will only hear a response when the searchcoil is right over the top of the target.

With a single sweep over a target, you will usually see a 2-digit target ID displayed on the LCD. Repeated sweeps back and forth over the target may cause the 2-digit target ID values to change with each sweep of the coil;...

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting SEARCH TECHNIQUES (continued) NUISANCE BURIED OBJECTS In some areas there is a lot of metallic trash which produces weak signals. These could include deeply buried objects, little bits and pieces of rusty iron and corroded foil. These items can be detected, but are difficult to pinpoint due to their depth and small size.

  • Page 29: Adjusting Sensitivity

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting SEARCH TECHNIQUES (continued) HOT ROCKS A hot rock is a rock which causes the metal detector to sound off because the rock contains iron minerals. They come in two basic types. Negative hot rocks (also called cold rocks) are usually magnetite or contain magnetite, and give a negative response because their ground cancellation phase is a higher number than the soil they are found in.

  • Page 30: Tips On Ground Canceling

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting SEARCH TECHNIQUES (continued) Tips on ground canceling When the T first turns on, the ground cancellation Phase Number is preset to 90. This will give a positive response on nearly all soils. If you search in the Discrimination mode, you will probably not have to cancel the ground.

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting Detecting Activities (continued) In some cases the parent mountain no longer exists. When a desert placer land surface is no longer situated where deposition processes are active, weathering disintegrates the surface material and it is washed away by surface erosion.
  • Page 33 TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting Detecting Activities (continued) Gold is valuable because it is a scarce commodity. Even in a good gold producing area, you may spend an entire day without finding any gold. Meanwhile you may dig bits and pieces of other metal.

    TEKNETICS Comprehensive Operating Manual & Guide to Metal Detecting Detecting Activities (continued) Shallow Water Hunting (continued) Salt water is highly conductive, and produces a strong signal which is like that of metal. Therefore the T is not suitable for use in or over salt water. In order to use the T over wet sand, or salt water beaches, do the following: 1.
