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. Throughout this operations manual, we are going to explain to you the controls and LCD Display Panel of the new Gold Strike as well as give you a few tips to get you prospecting. As with any new detector, we strongly encourage that you read the entire operations manual and call your local dealer with any questions.

The Gold Strike control panel and LCD display is designed to give the prospector constant control read out. In addition, the Gold Strike provides an innovative 2-tone audio system to give you more target information.

The rest is up to you. You’ve got the right detector, but you’ll have to decide where to search and then put in a lot of long, hard hours searching. And, of course, you’re going to have to learn your Gold Strike, read this instruction manual carefully and practice often. Drop us a line if you have any questions, comments or exciting gold hunting stories. In the meantime . . .

Happy Hunting! Fisher Research Laboratory

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. Adjust the stem length and coil angle so that the

search coil rests flat on the ground about 6 to 12 inches in front of and slightly to the right of your right foot (to the left of your left foot for left handers). Your arm should be straight and relaxed, the grip held loosely (see drawing on next page). The stem length is adjusted by loosening the lower lock nut and allowing the spring clip to snap into one of the

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. Leave just enough slack near the coil to allow it to be tilted completely backward and forward.

NOTE: A loose cable near the search coil may cause false signals, but don't wrap it so tightly that it pulls against the housing or the coil.

Adjust the stem length and coil angle so the coil rests flat on the ground about 6 to 12 inches in front of your foot. Move into your "search" position by leaning slightly and raising the coil about 2 inches off the ground. This should put the coil about 12 to 18 inches in front of your lead foot.

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. Attach the belt loop to the control housing by slipping it over the brass posts on the bottom of the control housing and pulling it toward the control panel to lock it in place.

4. Reconnect the cable to the control housing.

5. The control housing can then be mounted on your

belt or on the optional Fisher Chest Harness.

It is especially important that the cable connector be installed tightly to prevent false signals during body-mount use. Tight, but never tightened with anything but your hands.

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.

1. The POWER button turns the unit ON and OFF. One of the first things you will notice when you turn on your Gold Strike is the battery level display. Fresh batteries will show 9 volts; when the battery level is down to 6 volts, you have a little more than an hour of battery life left. The detector will not turn on if the search coil is not properly connected. This can prove to be a timesaving safeguard.

2. The LIGHT button enables you to use your back light for hunting in dim light situations.

3. The MENU button enables you to enter the “menu mode”, in which you can adjust any of six controls with the UP/DOWN arrow buttons: the discrimination level, the threshold level, the sensitivity level, an optional manual ground balance setting, the volume level, and the saving or recall of 3 of your favorite control setups with our memory feature. Notice that when the MENU button is pushed, the active control blinks — this is the control that can be adjusted with the UP or DOWN arrow buttons. To move to the next control, just press the MENU button again. When you have all your settings completed, press the P/P (MEM) button to return to the search mode (P/P stands for “Push-to-Prospect” on the Gold Strike).

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). When prospecting, you will choose an optimal discrimination setting between 0 and 99 that allows you to ignore most of the iron trash in your hunting area, without giving up any good targets. Also notice that the constant control readout shows you approximate settings at all times with a graphical icon, whether you are in the MENU mode or the search mode.

arrow buttons between –99 (high threshold) and +4 (low threshold). There are a couple of considerations in choosing a threshold setting: (1) If you prefer to have an audio threshold tone present while hunting, choose a setting between 0 and +4. This will allow your Gold Strike to react to the tiniest targets in a low mineralization environment. (2) However, if you plan to utilize the fast automatic ground tracking feature of the Gold Strike, set the threshold to a –5 or –10 setting for stable tracking performance (and even lower in harshly mineralized soils).

of 0 to a maximum of 10 with the arrow buttons when the SENS icon is flashing. As with most detectors, set the sensitivity higher for best depth performance in soils that are low in mineralization. As the mineralization gets worse, lower the sensitivity setting as needed. We recommend a sensitivity setting of 5 or lower for the most stable performance if the fast automatic ground tracking is enabled. Please note that a SENS setting of 0 or 1 will still yield excellent results.
