METAL DETECTOR
OWNER'S MANUAL
If you do not have prior experience
with a metal detector, 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. Expect chatter or
internal noise at high sensitivity.
2) Do not use indoors. This detector is for
outdoor use only.
appliances emit electromagnetic energy,
which can interfere with the detector. If
conducting an indoor demonstration, turn
the sensitivity down and keep the searchcoil
away from appliances such as computers,
televisions and microwave ovens. If your
detector beeps erratically, turn off
appliances and lights.
Also keep the searchcoil away
from objects containing metal,
such as floors and walls.
3) Use a 9-volt ALKALINE battery
only.
Do not use Heavy Duty Batteries.
Many household
Also available
with 11"DD coil
(Item# OMEGA-11DD)

  • 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 Adjusting the Armrest The armrest may be moved forward or backwards by removing the single screw and nut, and then repositioning the 2-piece armrest. Users with shorter arms may find the armrest more comfortable in the forward position. In order to move the armrest backwards, the plastic plug must be removed from the aluminum tube.

    ASSEMBLY (continued) Caution: Forcing in MIDDLE STEM with CAM LOCK raised may form a burr on camlock. If this happens, remove burr with knife to allow insertion. Position S-Rod upright. Rotate the LOCKING COLLAR fully in the counterclockwise direction. Insert your finger inside the tube and make sure the INTERNAL CAM LOCK is flush with the inside of the tube.

  • Page 6: Batteries

    BATTERIES The detector requires a single 9-volt ALKALINE battery (battery not included). Do not use ordinary zinc carbon batteries. Do not use “Heavy Duty” batteries. Rechargeable batteries can also be used. If you wish to use rechargeable batteries, we recommend using a Nickel Metal Hydride rechargeable battery.

  • Page 9: Basic Of Metal Detecting

    THE BASICS OF METAL DETECTING A hobby metal detector is intended for locating buried metal objects. When searching for metals, underground or on the surface, you have the following challenges and objectives: 1. Ignoring signals caused by ground minerals. 2. Ignoring signals caused by metal objects that you do not want to find, like pull-tabs.

  • Page 10: Emi

    THE BASICS OF METAL DETECTING (continued) 5. EMI (Electromagnetic Interference) The searchcoil produces a magnetic field and then detects changes in that magnetic field caused by the presence of metal objects. This magnetic field that the detector creates is also susceptible to the electromagnetic energy produced by other electronic devices.

    OPERATION and CONTROLS (continued) CONTROL KNOBS ARE AS FOLLOWS: 1. SENSITIVITY: a. Click right to turn on. Click left to turn off. b. Turning the knob clockwise increases the detector’s sensitivity; the higher the sensitivity, the deeper targets will be detected, and the more likely the detector will be to detect very small targets.

    OPERATION and CONTROLS (continued) TOUCHPAD CONTROLS ARE AS FOLLOWS: GND GRAB: Ground Grab™ Computerized Ground Balancing. The control allows you to set the detector’s internal ground setting equal to the phase of the ground you are searching over. See the section on Ground Balancing for a more thorough explanation of this feature and the reason for using it.

    TOUCHPAD CONTROLS (cont.) TONES: Number of Tones Selection In Discrimination Mode, the OMEGA indicates target type by audio tone. The TONES button allows the user to select one of four different ways to group target types by tone. Your selection depends on personal preference and search objectives. For example, coin shooters usually select d3 or d4.

  • Page 15: Ground Balancing

    GROUND BALANCING WHAT IS GROUND BALANCING? Why do I need to Ground Balance? 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 16: Ground Error

    The bottom left-hand corner of the display contains a graphic which indicates if your detector’s ground balance setting needs to be adjusted. The Omega has a tracking system which continuously analyzes the phase of the ground you are searching. It then compares this ground phase value with the detector’s internal Ground Setting indicated on the bottom right of the display.
  • Page 17 GROUND ERROR (continued) * When the detector’s internal Ground Setting is higher than the actual phase of the ground, the bars on the top of the graph will be illuminated. The bigger the error is, the more bars will show up. * When the detector’s internal Ground Setting is lower than the actual phase of the ground, the bars on the bottom of the graph will be illuminated.
