Page 3: About Your Gold Bug-2
Almost overnight, the Gold Bug became the standard against which all other gold-hunting detectors were compared. The next generation Gold Bug, the Gold Bug-2, is not meant to be a replacement for the original Gold Bug. Your Gold Bug-2 offers many of... - Page 4 ABOUT YOUR GOLD BUG-2 (continued) An audio boost mode, another new feature of the Gold Bug-2, makes it easier to find smaller nuggets at greater depths. Already a successful and proven feature of the Fisher Gold Bug line of land and underwater detectors, the audio boost mode automatically increases the volume of any faint signal, such as a small or deep gold nugget.

Page 6: Setting Up
UP The Gold Bug-2 comes to you just about ready to use. There are only three steps required: sliding the lower stem into the upper stem, connecting the loop coil to the control housing and adjusting the angle of the search coil. Take a look at page 3 and familiarize yourself with the parts of the Gold Bug-2 before proceeding. -
Page 7: Hipmounting
HIPMOUnTInG Your Gold Bug-2 is light and extremely well balanced; however, if you’re going to be swinging it for more than a few hours, you may want to “hipmount” it by removing the control box and strapping it to your waist. -

Bug-2 handle. COnTROl Panel Figure 5. 1. SenS: This knob adjusts the Gold Bug-2’s sensitivity to targets, and it doubles as a battery tester. By increasing the sensitivity, you can detect smaller and deeper targets, however, you’ll also pick up more false signals in mineralized soil or in areas of electrical interference. - Page 9 1/4-inch plugs. When using headphones with a stereo/mono switch, put the stereo/mono switch in the stereo position. Although, your Gold Bug-2 is equipped with a dust and moisture resistant speaker, we recommend that you always wear headphones while hunting to maximize the number of targets you hear.

Unlike the SENSITIVITY control, the MINERALIZATION switch also affects the retune speed, which is the amount of time it takes for your Gold Bug-2 to automatically retune itself after the search coil has passed over a target. A fast retune speed means a quick response to targets.

In either the AUDIO BOOST or NORMAL MODE, the Gold Bug-2’s sensitivity decreases as you increase MINERALIZATION settings from LOW to HIGH. MineraliZatiOn SWitCH In general, you should start searching with the MINERALIZATION switch set to LOW. -

If it is a “hot rock” or small ferrous object, there will be no sound. Some iron objects chirp or click. If it is nonferrous metal such as gold, your Gold Bug-2 will give a solid “beep.” Unlike the AUDIO BOOST and NORMAL modes, the IRON DISC mode is unaffected by the SENSITIVITY control and threshold settings. -

The threshold signal is a soft MINERALIZATION switches set to background tone heard when NORMAL and the SENSITIVITY operating the Gold Bug-2, is set by control set at something less adjusting a metal stem at the rear of than 10. If you’re working in the control housing. -
Page 15: Ground Reject Procedure
GROUnD ReJeCT PROCeDURe When your Gold Bug-2 is properly tuned or “ground balanced,” it will have only a minimum response to ground minerals when the search coil is raised or lowered. Precise adjustment of the GROUND REJECT control is critical to your success. The lower the MINERALIZATION or the higher the SENSITIVITY settings, the more important it is to maintain proper ground rejection. -
Page 16: Ground Reject Procedure
GROUND REJECT PROCEDURE (continued) Your objective now is to adjust the GROUND REJECT control so that there is no change or at least only a small change in the threshold hum as you bob the coil up and down. Start by clicking the small, center knob back to about 8. -
Page 17: Searching
Keep the search coil moving at a comfortable rate. Remember that the Gold Bug-2 is a motion detector and responds only when the search coil (or the target) is moving. Keep the search coil parallel to and as close to the ground as possible. - Page 18 Avoid hunting in the IRON DISC mode unless the area is so littered with ferrous trash that it’s impossible to hunt in any other way. The IRON DISC mode will cause your Gold Bug-2 to ignore ferrous objects and hot rocks, but it may also cause you to miss small gold nuggets.

Page 19: Pinpointing
With a little practice you’ll be able to zero in on most targets quickly and accurately. Use this procedure: 1. Once a buried target is indicated by the “beep” of the Gold Bug-2, continue sweeping the search coil from side-to-side, narrowing the search pattern. -
Page 20: Target Recovery
PINPOINTING (continued) the HOT SPOT was, and quickly mark the target location with your finger or digging tool. 7. For very strong signals, you may improve your pinpointing accuracy by adding one or more of the following steps: 1) Lift the coil until the signal is just barely heard. 2) Lower the sensitivity level. - Page 21 3. Once your target has been pinpointed by crisscrossing the target area with your search coil, lay your Gold Bug-2 so that the search coil is within easy reach but not close enough to detect your digging tool as you dig.
- Page 22 5. If the target sounds small (faint and soft), sprinkle some of the target dirt on top of the Gold Bug-2 search coil. If you get a response, you can set aside the rest of the dirt in your hand and concentrate on the dirt on your coil.

Page 23: False Signals
A false signal occurs when something that shouldn’t sound like a good target sounds like one. For example, the Gold Bug-2 may detect metal in your boots if you swing your search coil too close to your feet. Here’s some other sources of false signals, and here’s what to do about them. - Page 24 FALSE SIGNAL (continued) 4. Junk: Nails, pull tabs, beer cans, etc. The Gold Bug-2 was designed for extreme sensitivity to small bits of gold. That means it’s also extremely sensitive to small bits of ferrous metal. Solution: Hunt in the NORMAL MODE, but use the IRON DISC Mode to check targets to see if they’re ferrous.

Take a small nugget with you and do the same thing when searching in unfamiliar soil. 4. Practice. The Gold Bug-2 is easy to use, and it’s highly sensitive to gold. But you still have to learn how to use it. Read this instruction manual thoroughly and use your Gold Bug-2 often. -
Page 26: Coin Shooting, Beach And Relic Hunting
True, the Gold Bug-2 was designed for prospecting, but it’s also suitable for Treasure Hunting. Like most coin-shooting and relic hunting machines, the Gold Bug-2’s iron discrimination mode can be used to filter out trash targets in areas where relics and coins are normally found. -

MaInTenanCe Your Gold Bug-2 doesn’t require a lot of care 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 awhile, take the batteries out. -
Page 28: Using Headphones
UsInG HeaDPHOnes Using headphones (not included) improves battery life, and allows you to hear subtle changes in the sound more clearly, particularly if searching in a noisy location. For safety reasons, do not use headphones near traffic or where other dangers are present. This device is to be used with interconnecting cables/headphone cables shorter than three meters. -
