ABOUT YOUR DETECTOR The gold detector of the future is here! The Fisher Gold Strike takes over where our legendary Gold Bug series left off. With features that include fast automatic ground tracking, precision auto ground balance system, an innovative two-tone ID system, and an adaptive ground system made possible with our advanced digital signal processing.
SETTING UP Your Fisher Gold Strike is built to last for years. However, it's a sophisticated electronic instrument containing state-of-the-art components. Handle it carefully, care for it regularly, and it will give you years of dependable service. The Gold Strike requires little assembly. 1. Unpack your Gold Strike carefully and save the carton: it may come in handy if you ever have to return the instrument for service. 2. Slip the lower stem into the upper stem. 3.
SETTING UP holes in the center stem. The coil angle is adjusted by loosening the nylon wing nut on top of the search coil. NOTE: Remember, the longer the shaft, the more you'll have to bend your elbow to keep the coil off the ground and the sooner your arm will get tired. The CZ-70 Pro is balanced for comfortable searching in a tight semicircle around the front of the operator. 4. With the stem length properly adjusted, wrap the search coil cable snugly around the lower stem and the center section.
SETTING UP 5. Reconnect the coil cable to the control housing. Be careful not to cross thread it and make sure it’s snug, but hand tightened only. 6. With the shaft length and coil angle properly adjusted, you should be able to move into your search position by leaning forward very slightly and raising the angle so the coil rests flat on the ground about 6 to 12 inches in front of your arm. 7. (When using optional headphones) Plug into the headphones jack on the control panel.
BODY/CHEST MOUNT 1. Disconnect the cable from the control housing and unwind all but the last 12 inches or so from the stem. Secure the lower end of the cable with a Velcro strap at least 12 inches up from the coil. 2. Remove the control housing from the pistol grip by holding the grip with one hand and sliding the housing toward you with the other hand. 3.
CONTROL PANEL The Gold Strike control panel is an all new digital I/O System. The LCD Display provides you with a constant control readout showing you all of your current setiings, much like the knobs of an older style metal detector.

The POWER button turns the unit ON and OFF.
CONTROL PANEL a. When in the MENU mode, the DISC control can be varied from 0 to 99 with the UP and DOWN arrow buttons. A 0 discrimination setting will allow all metals to activate the high tone; a 99 discrimination setting fully discriminates out most iron targets, allowing only nonferrous objects (like gold) to activate the high tone (this two-tone audio system will be explained shortly).
CONTROL PANEL d. If the user chooses, the manual GROUND BALANCE can be adjusted with the arrow buttons when the GROUND icon is flashing. See the operation manual for more information on this procedure. We recommend all users take advantage of the high precision auto-ground balance system of the Gold Strike instead. That simple procedure will be described shortly. e. The VOLUME can be adjusted and listened to when the VOLUME icon is flashing by using the UP and DOWN arrow buttons. f.
CONTROL PANEL 7. The ALL METAL/DISC button enables you to toggle between two operating modes: a “true” all metal detecting mode or, with an advanced iron discrimination system activated.
QUICK START GUIDE We strongly encourage you to thoroughly read and understand everything in this operation manual prior to using your new Fisher Gold Strike. This will enable you to obtain the optimum performance when you prospect. However, we can provide a few quick suggestions that can help you get started. To begin hunting with your new Gold Strike, you will at least need to be familiar with the control panel (see page 6). 1. Turn ON the Gold Strike by pressing and releasing the POWER button. 2.
QUICKSTART GUIDE Sensitivity setting when prospecting in harshly mineralized soils, or when using the FisherTrack fast automatic ground tracking system. Try starting with a SENS setting of 5. 7. Set the VOLUME level you are comfortable with by pressing the MENU button until the VOLUME icon blinks, and using the UP and DOWN arrow buttons to adjust the audio level. 8. When the Threshold, Sensitivity, and Volume levels are set, push and release the P/P (“Push to Prospect”) button to enter the search mode. 9.
2 TONE AUDIO SYSTEM The two-tone audio system provides you with more information per sweep, acting as either a non-metal/metal I.D. system in the “all-metal” mode, or a ferrous/nonferrous I.D. system in the “discrimination” mode. While sweeping the Gold Strike search coil over a target, you may hear either one or two tones. The first tone, or “low” tone is to alert you to the presence of a target. The second tone, or “high” tone, if present, alerts you to the type of target.
LCD IDENTIFICATION SYSTEM The LCD will also show you an indication of the type of target you have found, independently of the audio tones, by showing you a number preceded by a “-” or “+” sign. The target identification system works as follows: When in either search mode (ALL METAL or DISC), a target will produce a number between 0 and 99 depending on how strong that target is (either due to its size or depth).
LCD IDENTIFICATION SYSTEM 3. To summarize: ALL METAL mode: - = ferrous target or positive hot rock + = nonferrous target DISC mode: - = discriminated target (incl.
GROUND BALANCING/TRACKING The Gold Strike offers three options for handling the soil mineralization you may encounter. Our new auto-ground balance system and our FisherTrak ground tracking system are made possible by our AFS© (Adaptive Feedback System) technology. We also provide an optional manual ground balance control. AUTO GROUND BALANCE: The precision automatic ground balance system will provide ground balance accuracy that exceeds any setting achieved manually.
FISHERTRAK AFS© “FisherTRAK©” FAST AUTO-GROUND TRACKING: To take advantage of the fast auto-ground tracking system of the Gold Strike, start by using the automatic ground balance procedure just described. Then, simply press the TRACK button on the panel to allow the Gold Strike to automatically adjust to changing ground conditions. Notice that the “TRACK” icon will be active on the display when the tracking system is ON.
FISHERTRAK AFS© stable tracking performance. If you are hunting in mineralized soil, we suggest setting the Threshold control to –5, -10, or even lower. We also suggest setting the Sensitivity control to 5, 4, or lower. If you experience unstable tracking performance, please adjust these controls accordingly.
SETTING MEMORY CONTROL Your new Gold Strike provides you with 3 memory locations to store your favorite control settings. These memory locations will store the DISC level, THRESHOLD level, SENSITIVITY level, and GROUND setting. Please note that the VOLUME level will not be stored and will remain at your current setting at all times. At this point, we would also like to remind you that your Gold Strike has a last-setting memory feature.
ADDITIONAL FEATURES AUTOMATIC LOW BATTERY WARNING: The Gold Strike will let you know when a low battery condition will begin to effect performance — the batteries must be changed at this time. When the batteries get too weak, the LCD will show a “LOW BATTERY” warning on the display. In addition, the audio system will produce a wavering tone to alert you to the low battery condition.
SEARCHING Good search techniques are every bit as important as having a good detector. 1. Once your controls are properly set, press and release the P/P touch pad, and move into your search position. Begin your search by walking slowly and sweeping the search coil in a tight semicircle. 2. Keep the coil parallel to the ground and as close to the ground as practical. This is extremely important for maximum coverage and depth.
SEARCHING 5. Keep the search coil moving at a comfortable rate. 6. Take your time. If you walk too fast you can overlap your sweeps and you’ll miss a lot of ground. If you swing your coil too fast, you could lose some sensitivity to deep and/or small targets. 7. The illustration below shows the GoldStrike search coil pattern and how it is effected by sweep speed, ground mineralization and search mode.
BATTERY REPLACEMENT Two 9-volt transistor batteries are located in separate compartments on the underside of the control housing. When you first turn on your detector you will see your battery level. It flashes for 3 seconds. A reading of 9V means you have maximum battery life. A reading of 6V indicates that you have approximately 11/2 to 1 hour left of battery life. CHANGING YOUR BATTERIES: 1.
TARGET RECOVERY Once you have identified and pinpointed your target, your objective is to recover it quickly and neatly, leaving virtually no trace of your excavation. There are almost as many ways to do this as there are Treasure Hunters. Whatever works for you is good enough as long as you don't break any laws, damage vegetation, or leave uncovered holes. Whichever method you choose, remember that responsible treasure hunters take pride in their ability to leave soil and vegetation intact and undamaged.
MAINTENANCE Your Gold Strike doesn't require a lot of care. It's built with highquality materials and it's splashproof and dustproof. But there are a few things you should do to keep it in peak operating condition. 1. If you're not going to be using it for a while, take the batteries out. Acid damage caused by leaking batteries can be severe. 2. Avoid extreme temperatures. Don't leave it inside a closed car that's sitting in the sun. Or even worse, the trunk of a car. 3.
