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; this device is
designed to work "into-the-noise", so
expect chatter 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 search coil
away from appliances such as computers,
televisions and microwave ovens. If
your detector beeps erratically, turn
off appliances and lights.
Also keep the search coil away
from objects containing metal,
such as floors and walls.
3) Use a 9-volt ALKALINE battery
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. Loosen both Locking Collars by rotating 100% counterclockwise Insert the Upper Stem into the S-Rod and click Silver Button into hole Position the lower stem with the silver button toward the back. Using the bolt and knurled knob, attach the search coil to the lower stem.
  • Page 5 ASSEMBLY Adjusting the Arm Rest The arm rest may be moved forward or backwards by removing the single screw and nut, and then repositioning the 2-piece arm rest. Users with shorter arms may find the arm rest more comfortable in the forward position.

  • Page 6: Batteries

    BATTERIES The detector requires a single 9-volt ALKALINE battery (battery not included). Do not use ordinary zinc carbon batteries. Rechargeable batteries can also be used. If you wish to use rechargeable batteries, we recommend using a Nickel Metal Hydride rechargeable battery. The battery compartment is located on the back side of the housing.

    QUICK-START DEMONSTRATION I. Supplies Needed • a Nail • a Zinc Penny (dated after 1982) • a Nickel • a Quarter II. Position the Detector a. Place the detector on a table, with the searchcoil hanging over the edge. Or better, have a friend hold the detector, with the searchcoil off the ground. b.

  • Page 8: Basic Of Metal Detecting

    All soils contain minerals. Signals from ground minerals can interfere with the signals from metal objects you want to find. All soils differ, and can differ greatly, in the type and amount of ground minerals present. The Delta has a preset gound eliimination setting. No user adjustment are required.

    THE BASICS continued 4. Size and Depth of Buried Objects When using the detector in the motion DISCRIMINATION mode, the relative depth of an object is displayed on the right of the display in a 5-segment format. A more accurate depth reading is available in a no-motion mode, using PINPOINT mode.

  • Page 10: How To Work The Controls

    OPERATION and CONTROLS POWERING UP Press • The detector always starts in the DISCRIMINATION mode. Motion is required. • Default sensitivity is at about 70% of maximum, (08). • All target categories except iron are illuminated, meaning that all metal objects will be detected except iron.

    HOW DEEP WILL IT GO? The Delta Metal Detector will detect a coin-sized object, like a quarter, to a distance of about 11” from the searchcoil at maximum sensitivity. Large metal objects can be detected to a depth of several feet. Detectability is directly related to the size of the metal object -- the larger the object, the deeper it can be detected.

Elimination occurs from left to right. When a category description (for example “IRON”) disappears from the display, then targets classified in that category will not be detected.

    OPERATION and CONTROLS cont. MODE SELECTIONS There are three selections under the MODE section of the display. • Press to toggle between DISCRIMINATION and ALL METALS. • Press at any time to activate PINPOINT mode. 1. DISCRIMINATION Mode This mode is the default mode, and requires the searchcoil to be in motion in order to detect and identify targets.

  • Page 16: Target Identification

    TARGET IDENTIFICATION In DISCRIMINATION mode, targets are identified both audibly and visually as follows: 1. Different pitch tones for different types of metals 2. A 2-digit target I.D. 3. An illuminated icon within the target category best describing it AUDIO TARGET IDENTIFICATION: Tones identify targets as follows: LOW TONE Ferrous objects, such as iron and steel, like nails and tin cans.
  • Page 17 TARGET IDENTIFICATION continued 2-Digit Target Identification The 2-digit value in the middle of the screen provides a specific target value to help identify buried targets more accurately. With practice in the field, you will learn to associate target values with specific objects. Coins are more likely to yield the same value with each pass of the coil due to their concentric shape.
