TERMINOLOGY The following terms are used throughout the manual and are standard terminology among detectorists. A relic is an object of interest by reason of its age or its association with the past. Many relics are made of iron, but can also be made of bronze or precious metals. RELIC IRON Iron is a common, low-grade metal that is an undesirable target in certain metal detecting applications. Examples of undesirable iron objects are old cans, pipes, bolts and nails.

Insert the MIDDLE STEM into the S-ROD, with the SILVER BUTTON pointed upward. ●7 Rotate the MIDDLE STEM until the SILVER BUTTON locates in the hole.
BATTERIES The detector requires two AA batteries. We recommend ALKALINE batteries (not included). Do not use ordinary “Zinc Carbon” batteries. Do not use “Heavy Duty” batteries. Rechargeable batteries can also be used. If you use rechargeables, we recommend using a “Nickel Metal Hydride” rechargeable battery. The battery compartment is located on the right side of the Control Housing. Both batteries should be installed with the negative terminal down. Remove battery tube: 1. Slide the battery door off. 2.
QUICK-START DEMONSTRATION I. Supplies Needed • Nail (made of iron) • U.S. Quarter (or silver coin) • U.S. Nickel • Gold Ring • U.S. Dime • U.S. Penny, dated after 1982 (post-1982 pennies are made of Zinc) (Most newer non-U.S. coinage also contains mostly Zinc) II. Position the Detector a. Place the detector on a table with the searchcoil hanging over the edge (or, have a friend hold the detector with the searchcoil off the ground). b. Keep the searchcoil away from walls, floors and metal objects. c.
THE BASICS OF METAL DETECTING This 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 nails. 3. Identifying a buried metal object before you dig it up. 4. Estimating the size and depth of objects, to facilitate digging them up. 5.
THE BASICS OF METAL DETECTING The searchcoil produces a magnetic field and then detects changes in that magnetic field caused by the presence of metal objects. This magnetic field the detector creates is also susceptible to the electromagnetic energy produced by other electronic devices. Electric fences, cell phones, cell phone towers, power lines, microwave ovens, lighting fixtures, TVs, computers, motors, etc., all produce EMI which can interfere with the detector and cause it to beep erratically. 5.
OPERATION and CONTROLS Press or to INCREASE or DECREASE menu settings. Press MENU to cycle through menu items: VOLUME, SENSITIVITY or NOTCH. Press and hold PP to enter Pinpoint. POWER ON/OFF Press MODE repeatedly to cycle through search modes: JEWELRY, COIN, ARTIFACT or CUSTOM.
THE DISPLAY Target Category Icons Icons will turn from outlined to solid indicating a detected target. A “blank” position indicates a Notched-out target category. Iron Target Category ID Numbers Menu Category Icons Mode Indicator Battery Level Indicator Target Depth Indicator Target-ID Coin-sized objects will be detected up to 9” deep. The 3-segment graphic indicator is calibrated to coin-sized objects. DEPTH INDICATOR Depth of Depth of Coin-Sized Coin-Sized Object Approx.
MENU The Menu items are located on the left side of the screen. During normal operation the Menu is inactive and the text icons are faded. Press to cycle through the Menu. Each press of moves to the next Menu item and when active the icon will be bold. Use ( ) within each menu item to make adjustments. Menu options: Adjust speaker volume from 0 to 20. The default setting is 7. With a setting of “0”, the detector will function as normal but it will not emit any sound when targets are detected.
MENU (Continued) The Notch control allows you to accept or reject different types of metals per each target category group. All categories are eligible for NOTCH. Each mode: Jewelry, Coin, Artifact and Custom has its own set of notches. NOTCH With Notch menu active, press “+” or “-“ to program the Notch feature. Each press of the “+” or “-“ cycles to a new category and the active position is indicated by a flashing icon.
MENU (Continued) Press and hold to activate. Searchcoil motion is not required; a motionless searchcoil over a metal target will induce sound. The screen will blank except for the 2-digit number display indicating target depth in inches. The scale is calibrated to coin-sized objects. The depth indication will vary as you scan your target. The target center is where the smallest depth indication displays. PINPOINT Tone and pitch of the audio will vary as the coil passes over the target.
TARGET IDENTIFICATION When metal objects are detected, the detector will emit a sound, a Target-ID Category icon will illuminate and a 2-digit Target-ID number will appear on the screen. Possible Target-ID numbers range from 1 to 99. This number represents the electrical conductivity of the target; higher numbers indicate more highly conductive targets. Target-ID Target indicators on the screen only represent the last object detected.
TARGET IDENTIFICATION (Continued) Jewelry, Coin and Artifact modes have predefined audio tones for the various Target Category groupings. The Custom mode is programmable and users can assign any tone to any of the Target Category groups. The Custom modes default tone for all categories is a single proportional tone (V.C.O.). V.C.O. varies in pitch and volume depending on the depth and size of the target. The custom tones are automatically saved when the unit is turned off.
DEPTH & TARGET DISPLAY The display shows the PROBABLE identification of the metal detected, as well as its PROBABLE depth. READING THE DISPLAY The detector will register a target upon each sweep of the searchcoil, when a buried target has been located and identified. If, upon repeated passes over the same spot the target identification reads inconsistently, the target is probably a trash item. With practice, you will learn to unearth only the repeatable signals.
DEPTH & TARGET DISPLAY 50-59. US. Zinc coins and many non-U.S. coins of recent vintage are classified here. 60-69. Copper coins, small silver coins (U.S. dime) 70-79. Medium sized silver coins (U.S. quarters) 80-89. Large silver coins (U.S. half dollars). 90-99. Very Large silver coins (U.S. silver dollar). When used in (Continued) areas outside the U.S.
HEADPHONE JACK This detector has a 1/4” headphone jack. It works with any stereo headphone that has a 1/4” plug. When the headphone jack is connected, speaker volume is disabled. Using headphones extends battery life and prevents the sounds from bothering bystanders. Headphone use also facilitates detection of the weakest signals. For safety reasons, do not use headphones near traffic or where other dangers are present. This device is to be used with interconnecting cables shorter than three meters.
CHARACTERISTICS & LIMITATIONS 1. This detector comes with a waterproof searchcoil. The searchcoil can be completely submerged into water. The control housing is weatherproof but cannot be submerged in water. 2. BURIED UTILITY LINES. This hobby metal detector is not designed to locate buried pipes or cables. First Texas Products manufactures a complete line of pipe and cable locators for this application. These are sophisticated instruments with functionality different from your hobby metal detector. 3.
