OWNER’S MANUAL

If you do not have prior experience with a metal detector, we strongly recommend that you:

1)Adjust the Gain to a low setting in the event of false signals. Always begin use at a reduced Gain level;

increase Gain only after you have become familiar with the detector.

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 Gain 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.

Congratulations!

Congratulations on your purchase of the new Gold Bug™ DP metal detector. The newly designed Gold Bug™ DP has been custom designed to find small gold nuggets, but unlike other specialized gold prospecting detectors, it can also be used for relic hunting and coin shooting.

Whether you use your Detector in your backyard, at the shoreline, in the mountains or fields afar, your investment will let you experience the excitement of searching for yet uncovered treasures and give you hours and years of outdoor enjoyment. Out on your own or with a group, places to use your Gold Bug™ DP are unlimited as buried treasures can be as near as your doorstep or as far as you wish to travel.

This manual has been written to help you get optimal use of your detector, so we hope you will read it thoroughly before your first outing and will also refer back to this manual from time to time to reinforce features and methods as you become more proficient in the field.

Happy Hunting from Fisher Research Labs!

Introduction to the Gold BugDP

DEEP PENETRATING GOLD NUGGET HUNTER

The New Gold Bug™ DP is unique among gold prospecting metal detectors for its combination of high sensitivity to small gold nuggets and its versatile function as an all-purpose treasure detector.

The controls and features are tailored to gold prospecting, including a sophisticated ground balancing system, separate control over signal gain and threshold, and a unique discrimination control system. These features also make for a great relic-hunting detector. While the Gold Bug™ DP makes for a highly competent coin-shooting detector, its user interface and features are not specifically designed for this purpose. As a coin-shooter, you will notice that the Gold Bug™ DP exhibits slightly lower sensitivity to high-conductivity coins, like a U.S. quarter; this is a result of its specialized design to emphasize sensitivity to small, low conductivity metals like gold nuggets.

According to FCC part 15.21 Changes or Modifications made to this device not expressly approved by the party responsible for compliance could void the users authority to operate this equipment.

This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

This radio transmitter 8188A-GB has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.

Antennas:

1.5” DD Coil, Part Number 5COIL-GBUG

2.11” DD Coil, Part Number 11COIL-GB

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes : (1) l’appareil ne doit pas produire de brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.

Le présent émetteur radio 8188A-GB a été approuvé par Industrie Canada pour fonctionner avec les types d’antenne énumérés ci-dessous et ayant un gain admissible maximal et l’impédance requise pour chaque type d’antenne. Les types d’antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l’exploitation de l’émetteur.

Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’établissement d’une communication satisfaisante.

TERMINOLOGY

The following terms are used throughout the manual, and are standard terminology among treasure hunters.

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 searchcoil’s detection field.

DISCRIMINATION

When the detector emits different tones for different types of metals, and when the detector "eliminates" certain metals, we refer to this as the detector "discriminating" among different types of metals.

Discrimination is an essential feature of professional metal detectors. Discrimination allows the user to ignore trash and other undesirable objects.

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.

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.

Sometimes, the desired target is made of iron. Property markers, for instance, contain iron. Valuable relics can also be composed of iron; cannon balls, old armaments, and parts of old structures and vehicles can also be composed of iron.

FERROUS

Metals which are made of, or contain, iron.

PINPOINTING

Pinpointing is the process of finding the exact location of a buried object. Long-buried metals can appear to the eye exactly like the surrounding soil, and can therefore be very hard to isolate from the soil.

V.C.O.

Meaning “voltage controlled oscillator”, the VCO audio method causes both the audio pitch and the volume to rise as signal strength increases. VCO improves the user’s ability to interpret a target’s size and depth. Very weak signals (for small or very deeply buried objects) have the faintest volume and the lowest pitch. Larger objects, and those closer to the searchcoil, will induce a higher volume and higher pitch sound.

GROUND BALANCE

Ground Balancing is the ability of the detector to ignore, or "see through" the earth’s naturally occurring minerals, and only sound a tone when a metal object is detected. The Gold Bug DP incorporates proprietary circuitry and programming to eliminate false signals from severe ground conditions.

ASSEMBLY

Adjusting the Arm Rest

The Arm Rest may be moved forward or backward 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. In order to move the Arm Rest backward, the plastic plug must be removed from the aluminum tube.

Arm Rest Strap

(optional accessory)

The Arm Rest Strap accessory can be purchased separately. Some users prefer to use the strap when swinging the detector vigorously, in order to hold the detector securely against the arm.

The detector can always be used without the strap, with no compromise to detector balance and stability under most conditions.
