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. Many household
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.
Also available
with 11"DD coil
(Item# DELTA-11DD)

  • Page 3: Terminology

    TERMINOLOGY The following terms are used throughout the manual, and are standard terminology among detectorists. Reference to a metal being "eliminated" means that the detector will not ELIMIN TION 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 backward 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 backward, the plastic plug must be removed from the aluminum tube.
  • Page 5 ASSEMBLY (continued) Caution: Forcing in MIDDLE STEM with CAM LOCK raised may form a burr on cam lock. 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.

    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

    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 9: Emi (Electromagnetic Interference)

    THE BASICS OF METAL DETECTING (continued) The searchcoil produces a magnetic field and then detects changes in that 5. EMI (Electromagnetic Interference) 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.
  • Page 10: Operation And Controls

    OPERATION and CONTROLS NOTE: Immediately after powering on, your detector's unique 10-digit serial POWERING UP number is displayed once on the LCD. Two digits are displayed at a time; five 2-digit numbers are displayed in sequence. This 10-digit serial number is the same serial number imprinted on the label inside the battery compartment.

    OPERATION and CONTROLS (continued) MENU SELECTIONS to increase or decrease sensitivity while the SENSITIVITY 1. SENSITIVITY line is highlighted. Maximum sensitivity setting is 12. Minimum sensitivity setting is 4. If the detector beeps erratically or beeps when there are no metal objects being detected, reduce the sensitivity.
