Craftsman 3300 manuale d’uso

OWNER’S MANUAL The Discovery 3300 is a professional metal detector . While the most difficult aspects of metal detecting have been automated, it is a sophisticated electronic device which requires an understanding of some basic features and metal detecting concepts. If you do not have prior experience with a metal detector , we strongly recommend[...]

3 TERMINOLOGY The following terms are used throughout the manual, and are standard terminology among detectorists. ELIMINA TION - 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 coil’ s detection field. DISCRIMINA TION - When the[...]

4 ASSEMBL Y Assembly is easy and requires no tools. ● 1 Position the lower stem (the straight tube) with the silver button toward the back. Using the bolt and knurled knob, attach the search coil to the plastic extension protruding from the lower stem. ● 2 Press the button on the upper end of the lower stem, and slide the lower stem into the up[...]

5 ASSEMBL Y Adjusting the Arm Rest Most people will find the standard position of the arm rest very comfortable. V ery large forearms and short forearms (particularly children’ s arms), can be accommodated by moving the arm rest forward. The arm rest is adjustable to three positions. To adjust, remove the screw from the underside, then press the [...]

6 Use ALKALINE batteries only . To install the batteries: ● 1 Remove the battery cover by disengaging the clip at the back. ● 2 Align the polarity of the batteries correctly , with the positive "+" toward the coil plug connection, as indicated by the + and – indicators on the housing. ● 3 Insert (2) 9-V olt ALKALINE batteries, wit[...]

7 Q UICK-ST AR T DEMONSTRA TION I. Supplies Needed • A Nail • A Quarter • A Pull-T ab from a beverage can • A Zinc Penny (dated after 1982) II. Position the Detector a. Place the detector on a table, with the search coil hanging over the edge. (or better , have a friend hold the detector , with the coil off the ground) b. Keep the search co[...]

8 VI. W ave the Nail over the Search Coil a. The Nail will not be detected. b. The Nail has been "Discriminated Out." VII. Press the “DISCRIMINA TION- ▲ ” touch pad twice. Five “R”s are now displayed. VIII. W ave all objects over the Search Coil The Nail and Pull-T ab will not be detected. The other objects will be detected with[...]

9 BASIC OPERA TION POWERING UP Press the POWER touch pad. • The detector will beep 4 times • All display segments will illuminate momentarily •T he SENSITIVITY and BA TTERY indicators will stay illuminated MOTION and NO-MOTION MODES Depending on the operation mode selected, the Discovery 3300 detects metal both with the coil in motion, or wit[...]

10 ALL MET AL MODE (Default Operation) The detector defaults to ALL MET AL mode after powering on. In this mode, all types of metals will be detected. An object’ s PROBABLE identification is indicated by the arrows at the top of the display . In addition, the PROBABLE depth of coin-sized objects is indicated by the rectangular segment indicators [...]

11 disappear , thus returning to detection the objects which fall into the corresponding categories. Discrimination Mode is a fixed-start-point elimination system. Objects are cumulatively eliminated as the level of discrimination increases. NOTCH MODE To selectively eliminate a category from detection within the metallic spectrum, use the NOTCH Mo[...]

12 BASIC OPERA TION continued 3) Notice the T arget Indication Note: Y ou can only ZAP objects that register under the seven left-most segments (from Iron to Zinc). 4) Press ZAP . An "R" appears under the segment to be eliminated. 5) Pass the search coil over the same object again. The undesirable object is eliminated from detection The Z[...]

13 AUDIO T ARGET IDENTIFICA TION (motion modes only) While the LCD (Liquid Crystal Display) is very accurate in identifying buried objects, the user in the field does not always maintain the display screen in his field of vision. Therefore, we have incorporated an audio feedback mechanism to alert the user to the nature of buried objects. This audi[...]

14 DEPTH AND T ARGET DISPLA Y (motion modes only) READING THE DISPLA Y The Liquid Crystal Display (LCD) shows the PROBABLE identification of the targeted metal, as well as the PROBABLE depth of the target, in inches. The detector will register a repeating, unchanging target identification when a buried target has been located and identified. If, up[...]

15 DEPTH AND T ARGET DISPLA Y (motion modes only) THREE DIGIT T ARGET INDICA TOR The three digit target indicator , in the middle of the LCD display , provides a specific target value to help identify buried targets more accurately . With practice in the field, you will learn to associate target values with the probable identification of buried obj[...]

16 ELECTROMAGNETIC INTERFERENCE The principle use for the Sensitivity Control is to eliminate Electromagnetic Interference (EMI). A hobby metal detector is an extremely sensitive device; the search coil creates its own magnetic field and acts like an antenna. If your detector beeps erratically when the search coil is motionless, the unit is probabl[...]

17 IN THE FIELD TECHNIQUES (motion modes only) When pinpointing a target, try drawing an “X”, as illustrated, over where the tone is induced. PINPOINTING Accurate pinpointing takes practice and is best accomplished by “X-ing” the target area. 1. Once a buried target is indicated by a good tone response, continue sweeping the coil over the t[...]

18 Swing the search coil slowly , overlapping each sweep as you move forward. It is important to sweep the coil at a consistent speed over the ground as you search. After identifying a target, your sweep technique can help in identifying both the location and the nature of the target. If you encounter a weak signal, try moving the coil in short, ra[...]

19 angles, you may have encountered multiple objects. If you are new to the hobby , you may want to dig all targets at first. With practice in the field, you will learn to better discern the nature of buried objects by the nature of the detector’ s response. Y ou may encounter some false signals as you proceed. False signals occur when the detect[...]

20 IN THE FIELD TECHNIQUES - Pinpoint Mode GROUND BALANCING Before using the PINPOINT mode, it is necessary to “Ground Balance” your detector , this ground balancing adjustment offsets the effects of minerals and salts in the ground. To GROUND BALANCE your detector: 1. Using the ALL-MET AL mode, find a patch of ground which is free of metal obj[...]

21 IN THE FIELD TECHNIQUES - Pinpoint Mode 5. Lower the search coil to the ground, maintaining it elevated about 1/2 inch above the surface (be sure that this ground does not contain metal). • If the detector emits sound with the search coil 1/2 inch over the ground, further ADJUSTMENT IS NECESSARY . • If the detector remains silent with the se[...]

22 IN THE FIELD TECHNIQUES - Pinpoint Mode In the Pinpoint Mode, coil sweep technique is not important. Rather , user retuning is critical. The detector does not automatically adjust to changing ground and environmental conditions; the operator is required to make the adjustment. If the detector sounds a constant tone over all areas of the ground, [...]
