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 electromagnetic energy, which can
interfere with the detector. If conducting an indoor demonstration,
turn the sensitivity down and keep the search coil away from
appliances such as computers, televisions and microwave ovens.
If your detector beeps erratically, turn off appliances and lights
(especially those with dimmer switches).
Also keep the search coil away from objects containing metal, such
as floors and walls.
3) Read this manual. Most importantly, review the Quick-Start Demo
(p.7) and Basic Operation (pp. 9-12).
4) Use 9-volt ALKALINE batteries only. Do not use Heavy Duty
Batteries.

Page 3: Terminology
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. -
Page 4: Assembly
ASSEMBLY Assembly is easy and requires no tools. 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. - Page 5 ASSEMBLY Adjusting the Arm Rest Most people will find the standard position 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.

Page 6: Batteries
BATTERIES Use ALKALINE batteries only. To install the batteries: Remove battery cover by disengaging the clip at the back. Align the polarity of the batteries correctly, with the positive "+" toward the coil plug connection, as indicated by indicators housing. 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. -

Page 9: Basic Operation
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. -
Page 10: The Display
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. -
Page 11: Mode Control (Discrimination)
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. -

Page 13: Audio Target Identification
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. -
Page 14: Sensitivity Adjustment
SEVERE GROUND CONDITIONS A secondary use for the Sensitivity Control is to reduce false detection signals caused by severe ground conditions. While your Discovery 1100 contains circuitry to eliminate the signals caused by most naturally occurring ground minerals, 100% of all ground conditions cannot be anticipated. -
Page 15: In The Field Techniques
IN THE FIELD TECHNIQUES PINPOINTING Accurate pinpointing takes practice and is best accomplished by “X-ing” the target area. 1. Once a buried target is indicated by a good tone response, continue sweeping the coil over the target in a narrowing side-to-side pattern. - Page 16 IN THE FIELD TECHNIQUES (continued) Swing the search coil slowly, overlapping each sweep as you move forward. It is important to sweep the coil at a consistent speed over the ground as you search. After identifying a target, your sweep technique can help in identifying both the location and the nature of the target.

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. -
