OWNER’S MANUAL
The
Discovery 1100 is
an easy to use detector.
The most difficult aspects of
metal detecting have been automated.
However, if you are new to the hobby,
we strongly recommend that you:
1) Adjust the Sensitivity to a low setting
in the event of false signals. Always begin
use at a reduced sensitivity level; increase to full
sensitivity after you have become familiar with the
detector.
2) Do not use indoors. This detector is for outdoor use only. Many
household appliances emit elec

TERMINOLOGY The following terms are used throughout the manual, and are standard terminology among detectorists. ELIMINATION Reference to a metal being "eliminated" means that the detector will not emit a tone, nor light up an indicator, when a specified object passes through the coil’s detection field. DISCRIMINATION When the detector emits different tones for different types of metals, and when the detector "eliminates" certain metals, we refer to this as the detector "discriminating" among di

ASSEMBLY Assembly is easy and requires no tools. 1 Position the lower stem (the straight tube) ● with the silver button toward the back. Using the bolt and knurled knob, attach the search coil to the plastic extension protruding from the lower stem. 2 Press the button on ● the upper end of the lower stem, and slide the lower stem into the upper stem. Adjust the stem to a length that lets you maintain a comfortable upright posture, with your arm relaxed at your side, and the search coil parallel

ASSEMBLY Adjusting the Arm Rest Most people will find the standard position of the armrest very comfortable. Very large forearms and short forearms (particularly children’s arms), can be accommodated by moving the armrest forward. The armrest is adjustable to three positions. To adjust, press the silver button on the underside, and move the armrest to one of the alternate positions. If you cannot fully depress the button with your finger, use a narrow object, such as the blunt end of a ballpoin

BATTERIES Use ALKALINE batteries only. To install the batteries: 1Remove the ● battery cover by disengaging the clip at the back. 2 Align the polarity ● of the batteries correctly, with the positive "+" toward the coil plug connection, as indicated by the + and – indicators on the housing. 3 Insert (2) 9-Volt ALKALINE batteries, with the contacts pointed inward, ● and press down on the back of the batteries to snap them into place. Some brands of batteries will require moderate force to clear

BASIC OPERATION POWERING UP Press the ON touchpad. All display indicators will illuminate momentarily. The 4-segment pyramid-shaped Sensitivity Indicator will illuminate on the left side of the display. The 4-segment pyramid indicates that the detector is at full sensitivity. When an object is detected, the object will be identified by a tone, a display indicator, and a depth indication. A two-minute “warm-up” is required before the detector reaches full sensitivity.

BASIC OPERATION (continued) The RIGHT SIDE of the display classifies objects into three categories. Silver/Copper: ------------------------------------------ Objects composed of silver and cooper will illuminate this arrow. Buried and heavily oxidized metal objects, such as old tin cans, can also fall into this category. Larger aluminum objects, like beverage cans, will sometimes fall into this category. Mid-Range: ------------------------------------------------ Mid-range objects cover a large

BASIC OPERATION (continued) The MODE CONTROL The MODE touchpad allows for the elimination from detection of unwanted metal objects. By pressing MODE, the user toggles among four different discrimination settings. If an object is detected during mode selection, the detector will exit mode selection. If this happens, you will need to press MODE again and begin mode selection over again. To avoid this, keep the detector stationary and reduce sensitivity before pressing MODE. During MODE (or discri

AUDIO TARGET IDENTIFICATION While the LCD (Liquid Crystal Display) is very accurate in identifying buried objects, the user in the field does not always maintain the display screen in his field of vision. Therefore, we have incorporated an audio feedback mechanism to alert the user to the nature of buried objects. This audio feedback system first alerts the user to the presence and classification of objects, whose nature and location can be confirmed using the LCD display. The detector will sou

SENSITIVITY ADJUSTMENT ELECTROMAGNETIC INTERFERENCE The principle use for the Sensitivity Control is to eliminate Electromagnetic Interference (EMI). A hobby metal detector is an extremely sensitive device; the search coil creates its own magnetic field and acts like an antenna. If your detector beeps erratically when the search coil is motionless, the unit is probably detecting another magnetic field. Common sources of EMI are electric power lines, both suspended and buried, motors, and househ

CARE AND MAINTENANCE Your Discovery 1100 Metal Detector is an example of superior design and craftsmanship. The following suggestions will help you care for your metal detector so you can enjoy it for years to come. Keep the detector’s chassis dry and do not let water enter it. If the chassis gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits. Use and store the detector only in normal temperature environments. Temperature extremes can short
