    TABLE OF CONTENTS Introduction ..........3 Terminology .

  • Page 3: Introduction

    Out on your own or with a group, places to use your F19™ are unlimited as buried treasures can be as near as your doorstep or as far as you wish to travel.

  • Page 4: Terminology

    TERMINOLOGY The following terms are used throughout the manual, and are standard terminology among detectorists. RELIC 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.

  • Page 5: 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 6 ASSEMBLY Caution: Forcing in MIDDLE STEM with CAM LOCKING LOCK raised may form a burr on COLLAR cam lock. If this happens, remove burr with knife to allow insertion. INTERNAL CAM LOCK Assembly is easy and SILVER BUTTON requires no tools. MIDDLE STEM Position S-Rod upright.

  • Page 7: Batteries

    BATTERIES A 3-segment battery indicator at the top-left of the display indicates the battery condition. The detector requires a single 9-volt ALKALINE battery. Do not use ordinary zinc carbon batteries. Do not use “Heavy Duty” batteries. Such low quality batteries may work in the detector but have a short life and are prone to leakage.

  • Page 8: Quick-Start Demo

    QUICK-START DEMONSTRATION Supplies Needed • a Nail • a Zinc Penny (dated after 1982) • a Nickel • a Quarter 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.

  • Page 9: Headphones

    Use with headphones (not included) The F19™ is equipped with a 1/4” headphone jack. Any headphones with a stereo plug will work; headphones with a mono plug will not work. Using headphones extends battery life, and also prevents the sounds from bothering bystanders. It also allows you to hear subtle changes in the sound more clearly, particularly if searching in a noisy location.

    4. Estimating the size and depth of objects to facilitate digging them up. 5. Eliminating the effects of electromagnetic interference from other electronic devices. Your F19™ metal detector is designed with these points in mind. 1. Ground Minerals All soils contain minerals. Signals from ground minerals can interfere with the signals from metal objects you want to find.

  • Page 11: Trash

    THE BASICS OF METAL DETECTING 2. Trash If searching for coins, you want to ignore items like aluminum foil, nails and pull-tabs. These undesirable items are generally identified toward the lower end of the 1-99 scale. You can listen to the sounds of all objects detected, and decide on what you want to dig up.

  • Page 12: Operation And Controls

    OPERATION & CONTROLS POWERING UP • Click the left knob to turn the detector ON. • After clicking the knob on, continued clockwise rotation will increase the “sensitivity” in DISC Mode or the “GAIN” in ALL METAL Mode. • We suggest keeping the GAIN below 70 until you become familiar with the detector’s operation.

  • Page 13: Control Panel

    CONTROL PANEL DISCGND BAL CONTROL KNOBS: 1. OFF/ON/GAIN 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.

  • Page 14: Touchpad Controls

    CONTROL PANEL GAIN versus THRESHOLD “Gain” increases, or multiplies, the strength of signals from buried metal objects. For maximum detection of the smallest or most deeply buried objects, increase the Gain. To minimize the weakest signals, reduce the Gain. “Threshold” controls the detector’s audio level. Positive threshold values increases the audio response of weak target signals.

  • Page 15: Operating In All Metal Mode

    Unwanted Noise Read the section on Electromagnetic Interference. The F19™ is a highly sensitive device. It is intended for use outdoors. Indoor operation will subject it to interference from a wide variety of devices in the home or office.

  • Page 16: Reading The Display

    OPERATING IN ALL METAL MODE Reading the Display Most gold prospecting and relic hunting is done by ear. Listen for the louder sounds, riding on top of the constant background hum. As you sweep the searchcoil, notice the Fe (iron oxide) scale to the left of the display.

  • Page 17: Operating In Discrimination Mode

    OPERATING IN DISCRIMINATION MODE Discrimination is used to eliminate trash metal objects (e.g. nails, foil, pull-tabs) from detection. The searchcoil must be in motion to detect metal. The Discrimination Mode is less sensitive to small and deep objects than the All Metal Mode. Ground Grab ®...
  • Page 18 The overload volume signal will always sound off in the event of signal overload, even with the volume set to 0. Because the F19™ is so sensitive to even the smallest iron targets, the detector incorporates FeTone™, Adjustable Iron Audio, a feature to reduce the volume of iron targets to minimize user fatigue.
  • Page 19 OPERATING IN DISCRIMINATION MODE V-Break (Change audio for certain targets) V-Break is a feature that allows the user to change the audio response of certain targets. V-Break allows the user to program the detector so that any target with an ID in the range of 0 - 80 can induce a LOW tone. Examples: The user sets V-Break to a desired setting (e.g.

  • Page 20: Unwanted Noise

    OPERATING IN DISCRIMINATION MODE Unwanted Noise Read the section on Electromagnetic Interference. This is a highly sensitive device. It is intended for use outdoors. Indoor operation will subject it to electrical interference from a wide variety of devices in the home or office. In Discrimination Mode, when you sweep the coil over the ground it will usually be quieter than when holding the detector still.
  • Page 21 OPERATING IN DISCRIMINATION MODE SIGNAL Each time a target is detected, bars will illuminate on the bottom left showing the strength of the target’s signal. If all 7 bars illuminate, the target signal is strong. This may be a large metal object. Or it may be a coin-sized metal object close to the surface.
  • Page 22 This discrimination interface for the F19™ was designed especially for relic- hunting. Relic hunters want control over what sizes of iron are detected, and also control over which targets are detected with a low-tone. Target values of 39 or less are ferrous.

  • Page 23: 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 stronger than a buried metal object. The magnetism of iron minerals, found in nearly all soils, causes one type of interfering signal.
  • Page 24 GROUND BALANCING Understanding ground conditions assists the user in setting up the machine, knowing when to readjust ground balance, and in understanding the responses of the machine while searching. This detector displays two kinds of ground data: 1. The type of mineralization (which affects where the ground phase should be set).
  • Page 25 GROUND BALANCING The goal of the Ground Balancing procedure is to eliminate the sound as the searchcoil is being pumped over the ground. In some soils, the sound is not completely eliminated. After balancing to ground with Ground Grab ® COMPUTERIZED GROUND BALANCING (GG) some users may want to further adjust the ground balance setting manually.

  • Page 26: Ground Balancing Technical Info

    GROUND BALANCING -Technical Info BARGRAPH The Fe 7-segment bar graph indicates the amount of ground mineralization, independent of type, expressed as an equivalent volume concentration of magnetite (Fe ). It updates every second. It is sensitive to motion and will give the most accurate readings if you pump the searchcoil up and down several times over the ground.

  • Page 28: Gold Prospecting

    GOLD PROSPECTING In the United States, gold is commonly found in the western states, Alaska and in a few localities in the Appalachians. Hillsides are the best areas for gold prospecting using a metal detector, because hillsides cannot be cleaned out by panning and dredging the way streams can.

  • Page 29: Relic Hunting

    The F19 can handle the toughest ground mineralization, capable of ground balancing all the way to salt. With its fast retune speed and biaxial searchcoil, the F19 creates superb target separation with impressive depth.

  • Page 30: Hot Rocks

    HOT ROCKS A hot rock is a rock which causes the metal detector to sound off because the rock contains iron minerals. They come in two basic types. Negative hot rocks (also called cold rocks) are usually magnetite or contain magnetite, and give a negative response because their ground balance value is a higher number than the soil they are found in.

  • Page 31: Electromagnetic Interference (Emi)

    At home, in a store, or in an urban environment, there may be several different sources of interference present simultaneously. All metal detectors generate a certain amount of internal electronic noise. The F19™ is specifically designed to enable you to work into the noise. Experienced users, striving for maximum depth, often adjust the machine to search with a constant audible background sound, and then listen through that noise for the sound of real targets.
  • Page 32 EMI is usually easier to control in the All Metals Mode than in the Discrimination Mode. On the F19™, setting the discrimination level between 20 and 30 will usually reduce interference. In the Discrimination Mode, the detector may chatter if the...

  • Page 33: Search Techniques

    SEARCH TECHNIQUES Target Verification After detecting a target, do the following: WRONG 1. Walk around the target in a circle. 2. While circling the target, continue sweeping the searchcoil across the target. 3. Sweep once every 30° or 40° of the circle.

  • Page 34: Target Pinpointing

    TARGET PINPOINTING After you have identified a target using Discrimination Mode, press-and-hold the PINPOINT button to identify the target’s exact location. This technique can yield more information about the target’s shape and size and also find its exact location to facilitate extraction. Pinpoint as follows: 1.
