Bounty Hunter Eliminator X-3 Operating Instructions

Introducing your new DISCRIMINATOR . . .

Congratulations on purchasing one of the finest discriminating metal/mineral detectors available anywhere at any price! Your Bounty Hunter instrument is a completely solid state precision accomplishment that will bring you many hours of treasure hunting enjoyment as well-as possibly some very valuable "finds."

Our instruments have been designed by Treasure Hunters for Treasure Hunters with every advance in the electronic field employed to insure maximum sensitivity, dependability, and success in the field.

With any detector, operator skill and familiarity with the instrument will deter mine, in large part the success of the hunt. We recommend that you read thoroughly the operating instructions _and spend some time familiarizing yourself with the instrument . The time you spend will pay off handsomely later.

BASIC OPERATION (Outlaw/X-3)

1. METAL DETECTION WITH THE 6" STANDARD COIL

(For meter operation, see page 5).

1.1 Set detector controls to "NORM" for normal metal search.

1.2 Hold detector in the search position with the coil about 1/2 inch above ground or floor. (See Search Stance on page 7).

1.3 Turn ONOFF/VOLUME control to ON. Rotate TUNING control until an audible tone is heard. Adjust tone volume to comfortable level.

1.4 Rotate TUNING control to point where all sound ceases. This is called the

"NULL" position. To one side of the "NULL" a METAL search tone will be generated to the other side of the NULL, a MINERAL search tone will be produced.

2. TUNING FOR MAXIMUM SENSITIVITY:

2.1 "BFO"--Rotate "TUNING" control toward "METAL" until an oscillating sound like an outboard motor or electric razor is heard.

"TR"--Rotate "TUNING" control toward "METAL" until a tone is barely buzzing or just at the edge of making a sound.

NOTE

The "NULL" width may vary with soil conditions. As a rule the "NULL" position is very narrow in the "BFO" tone position, while the "NULL" width for "TR" may be 1/4 inch or more in width on the TUNING control.

2.2 Place a nickel ring, or something of comparable size on the ground or floor for a practice target Pass the search coil over the target in a side-to-side motion as shown below, keeping the coil as level as possible and about 1/2 inch from the floor or ground. You will notice the target signal is loudest at the center of the coil.

As the search coil passes over the "target" the search tone alters to indicate the target location. Figure 5 shows how the BFO search tone might appear if plotted on a graph. The search tone alters from a low buzz to a high squeal. Figure 6 shows a typical target response with the TR search tone. The TR re response is more abrupt and sharply defined.

3. PINPOINTING THE TARGET WITH THE 6 INCH COIL

When operating with the 6 inch coil, if a target is located generally with a side-to-side sweep, the exact location may be determined by also passing the coil in a forward and back sweep as shown in Figure 7 at the right.

When using the 6 inch coil, try to maintain the 1/2 inch distance above ground when scanning to insure a steady basic search tone. You will notice as you raise or lower the coil that the tone varies with the height above ground. This is the result of electronic "de-tuning" and will cause a target-type signal response.

3.2 In actual field use the detector response will vary with size and/or depth of target. If a faint response is received during a normal search, the TUNING control must be rotated further from the NULL to increase the signal strength to overcome soil resistance to the coil force field. Large targets may be detected at a greater depth than smaller targets.

4. METAL DETECTION WITH THE 6" x 12" TRIPLE COIL

4.1 The triple coil must be used if maximum depth penetration is desired or if highly mineralized soil is encountered. The center coil functions in a normal fashion while the compensating coils at each end "neutralize" the mineralization or "ground effect" caused by highly mineralized soil. As a result, your Bounty Hunter Discriminator X-3 or Outlaw will detect targets in difficult areas that would render most other detectors useless

4.2 Figure 8 shows the design of the triple coil.

You will notice as you use this coil that raising or lowering coil height will not as readily cause a target type signal as with the 6" standard coil (De-tuning).

The triple coil is also useful for "coin-shooting" at the beach, as salty wet sand can cause confusing signals that can make other coils all but useless. Both the 6" Standard and 6" x 12" triple coils are completely waterproof and safe to use submerged.

4.3 Due to the unique coil design, the compensating coils at either end may be used to triple the search scan area as well as overcome mineralization.

You will notice as you pass the compensating coil over the target that instead of an increase in signal frequency or loudness, you will obtain a decrease or down swept tone. (See figures 9 and 10.) If a target is suspected as a result of the decreasing tone it may be confirmed by an x-shaped pass over the area by the center coil.

5. MINERAL DETECTION

5.1 Preparation for MINERAL detection is identical to that for METAL except that TUNING control must be rotated to the MINERAL side to get the proper response.

5.2 As mineral bodies vary in size and depth, there are no typical tone patterns to illustrate here. If you have some ore samples from your area, you may practice to see what kind of tone response to expect before beginning serious search.

6. USING EARPHONES

6.1 Many experienced treasure hunters prefer to use earphones with the detectors There are many reasons for use of earphones . . . they overcome distracting noise such as from traffic, jet plane, wind, ocean surf, etc., that may mask a target signal from a deeply buried coin or object. If you cannot discern the delicate signal from one of these possible valuable targets, you are not realizing the full potential of your instrument. Your Bounty Hunter dealer can furnish you with a pair of quality earphones to increase your treasure hunting enjoyment and productivity.

7.1 USING THE METER TO MEASURE SIGNAL INTENSITY (Proximity to Target)

NOTE: INSTRUMENT MUST BE TUNED FOR AUDIO SIGNAL BEFORE METER CAN OPERATE PROPERTY. The meter responds to the audio signal; therefore, it will not operate properly without correct audio tuning.

FIGURE 11. INTENSITY/DISCRIMINATING METER.

"DISCRIMINATE" SCALE indicates bad (ferrous) or Good nonferrous) targets.

INTENSITY SCALE Records target signal intensity and duration to determine target depth and size.

BATTERY CHECK If needle reads between these marks or higher when the control Is set to Batt Check,"oscillator (detecting) batteries ore good. If needle will not swing enough to reach the marks. replace 9 volt battery pack . When audio signal is weak, replace 12 volt battery pack .

7.2 Set detector controls to "NORM" for normal metal detection.

7.3 Adjust TUNING control to desirable search setting (See TUNING, section 2.)

7.4 Hold detector in search position (Figure 14) so coil is about l/2 inch above ground.

7.5 Turn METER ADJUST control clockwise until the needle moves slightly to the right away from the "0" (zero) setting. The needle is now set for normal response and will indicate proximity to the target. In this position, needle will deflect all the way to the right as a near-surface target is passed over with the coil. With a bit of practice you will be able to determine the depth, size and even the shape of some targets using your meter properly.

7.6 'Weak" Meter Signal

If a deeper or smaller target is passed over, the meter will respond less. If a weak target signal is acquired, rotate the METER ADJUST control to make the meter more responsive. This will help you "pinpoint" the target. If this does not produce an improved reading, retune the detector.

7. 7 "Too-Strong" Meter Signal

Sometimes a large or shallow target will cause the meter to overreact or "peg" against the high mark. Readjust meter with the METER ADJUST control until normal needle motion is achieved over the target.

7.8 With the detector controls set for normal search (Norm), the detector will detect ALL metals, ferrous or nonferrous.

8. THE DISCRIMINATING FEATURE

The Discriminating feature will operate with either the 6" standard coil or the 6" x 12" Triple coil search head. Only the center coil will discriminate properly on-the triple coil.

The Discriminating feature enables the treasure hunter to determine whether the on-target audio signal is caused by a ferrous or a nonferrous object. Ferrous metals are iron or iron-based alloys that are magnetic or magnetically responsive and which comprise the largest percentage of target signals to the treasure hunter.

Nonferrous metals are such as gold, silver, brass, copper or any nonmagnetic metal. All coins are made of nonferrous metals as are most valuable metallic objects.

The Discriminator lets you identify the target before you dig, thus increasing your percentage of worthwhile finds.

8.1 USING THE METER TO DISCRIMINATE

(a) Set the detector controls to "DlSC" for discriminate.

(b) Hold the detector in the search position about 1/2 inch from the ground to one side of the target.

(c) Use the METER ADJUST control to center the needle between the red (bad) and green (good) areas on the dial. Now the needle is ready to "read" the target.

(d) Make a slow side-to-side pass over the target area, preferably from right to left. The needle will deflect to one side or the other.

(e) To "read" the target, observe the direction of the fir t strong deflection of the meter each time the coil is passed over target. Figure 12 shows what the needle might do as a typical Bad (ferrous) target is "read". For practice purposes, use a coin or ring for "Good" target; a tin can or pop bottle top for a "Bad" target.

(f) Figure 13 shows the first deflection of the meter needle as the coil passes over · "good" or nonferrous target. Do not try to hold the coil still over the target to "read" it, ·s the meter needle will just oscillate as it tries to "center" itself.

GET THE MOST OUT OF YOUR METAL DETECTOR WITH PROVEN SEARCH TECHNIQUES

Stand with your arm extended slightly in front of your body. Don't bend or stoop but stand in an upright position that Is comfortable By holding the detector out slightly from your body you are in o position to observe the slightest difference in response.

Adjust the telescoping coil rod out (or in) until the Search Head is about %" above the ground Adjust the search head so it is parallel to the ground.

SWEEP

With the detector in search position swing the search coil gently side to side. Slightly overlap each sweep as you move forward (or backward). Make sure the search coil stays approximately the same height (%") above the ground and don't allow it to lift on the outside edges of the sweep This will cause false readings. Keep each sweep slow about three seconds from one edge to the other.

GRID

To make sure you search an area thoroughly without gaps you may wish to lay out the search area in d grid pattern. Stake out two parallel strings the width of your sweep (about three feet wild) and sweep this area thoroughly. Next move one string over and make a new search area and so on until the entire area has been covered. You may also grid an area mentally using trees rocks buildings etc. as points of reference.

BATTERY REPLACEMENT

Access to the battery packs is gained by pulling out on the nylon snaplok fastener on the battery cover on the rear of the unit and removing the cover.

Your detector is equipped with two battery packs. The larger pack Is the l2 volt supply for the audio circuitry and holds 8: size AA penlight batteries. The smaller pack is the 9 volt supply for the oscillator and hold 6 size AA penlight batteries. These batteries are easily removed and replaced in the packs by pressing the battery against the spring on the negative end and pulling out or pushing in at the positive end of the battery. 11- sur- to observe battery polarity when replacing batteries. The holder is marked on the inside + or-- to show proper battery orientation.

The battery lead connectors snap to the battery pack terminals as shown at the right. Do not reverse these connectors or the detector will not operate properly.

Any size AA penlight battery will suffice for replacement but longer life can be expected using Heavy Duty or Alkaline cells.

When replacing the battery cover, insert the cover tabs in the slots, close the cover inserting the snap-lok fastener through the round hole and press the fastener until it snaps into the locked position.

CAUTION: When the detector is not in use it is good practice to remove the battery packs from the unit as weak batteries will sometimes vent and leak. Damage from battery leakage is corrosive and is NOT covered by the warranty Play it safe!
