DE VI C E I NTRODUC TI O N M ENU The menu screen allows you to access all the FORS Tech settings. You can go to the menu screen by pressing one of the up/down/+/- switches while on the main screen and adjust the settings of the device. Now let's take a look at these settings: MODE: MODE GEN FORS Tech has 4 predefined search modes based on ground conditions and target type. During your search, you can select one of these modes and quickly personalize its settings in the menu if you want to.
DE VI C E I NTRODUC TI O N You can customize ID Masking according to your needs. Each mode has its own default ID Masking value in the menu. When you change the mode, the ID Masking value preset for that mode is displayed. This does not affect the ID Masking levels set by the user in other modes. ID Masking is not active in the General Search mode. For detailed information on Target ID and how to use ID Masking, please refer to the section TARGET ID and ID MASKING (pages 22-23).
DE VI C E I NTRODUC TI O N The brightness level of the LCD panel on the system box affects power consumption a lot. Therefore, the backlight illuminates during menu access and ground balancing. It does not illuminate during searching or target detection. On the other hand, the brightness level of the numeric display on the handle affects power consumption relatively less. It illuminates during target detection and pinpointing.
DE VI C E I NTRODUC TI O N IMPORTANT DETAILS ABOUT MENU USAGE: * If no button is pressed for a few seconds after accessing the menu, the device will go back to the main screen. If you do not want to wait, you can press and release the pinpoint button once to go to the main screen as well. * Do not turn off the device while the menu screen is displayed.
SEARC H MODE S GENERAL SEARCH MODE (GEN): Sometimes referred to as the ''All Metal'' mode, this is the deepest mode of the device. Different than the other modes, this mode has a constant threshold sound in the background that enables the user to use his/her own judgment. In the General Search mode, the device will detect all targets (metal, high mineralized rocks etc.) without discrimination.
SEARC H MODES If you want, you can use the ID Masking to ignore unwanted targets. The ID Masking default value is set to 10. We recommend you to change this value according to the type of target. CONDUCTIVE GROUND (COG): This is the special mode of FORS Tech designed for conductive ground (wet beach sand, alkali sand etc.). What is special about this mode is that it will not react to iron or similar targets within the same range and that the device will ground balance easily on all types of ground.
GROUND BAL AN CE One of the following may happen as a result of improper ground balancing: -The device gives a signal when the coil is swept over the ground where there is no target. -The device is silent but loses detection depth for certain metals. -The device receives target-like signals next to holes and dips. The above mentioned situations do not only occur as a result of improper ground balance adjustment.
GROUND BAL AN CE After the ground balance button is released, the device will work in the General Search mode and the ground balance value will remain on screen for a while. (If you do not want to wait for this period you can go to the main screen by pressing and releasing the pinpoint button once). This gives you the opportunity of fine tuning the automatic ground balance value. Please refer to the following MANUAL GROUND BALANCE section for more details.
GROUND BAL AN CE 4. Continue the above process until the sound is eliminated. If the sound is not completely eliminated, then you can fine tune. For fine tuning, follow the numbers above the symbol and use the + and - switches. The sound may not be eliminated completely on some types of ground although you have fine tuned.
GROUND BAL AN CE GROUND BALANCE VALUE: The ground balance value indicates the type of ground. Some typical ground types are as follows: 0-25 25-50 50-70 70-90 Wet salt water or wet alkali soils Wet salt water and wet alkali soils covered with dry layers Regular, low-quality soils Highly magnetic soils, magnetite or maghemite and similar highly mineralized soils, black sand IMPORTANT DETAILS ABOUT GROUND BALANCE: When the device is turned on, the ground balance value is preset to 90.
SENSI T I VI T Y and THR ES HO L D Adjusting these two settings correctly is critical for the device to work at its best performance and without noise. It is possible to obtain an average performance with the startup settings. However, to be able to have better detection depth in clean areas or to be able to search in tough ground conditions, these two settings must be adjusted properly.
TARGE T I D and I D MAS KI N G As mentioned before, Target ID is a 2-digit number produced by the detector and it gives you an idea about what the target may be. The number is displayed both on the LCD panel and the numeric display on the handle. Under certain conditions, the device may generate multiple IDs for the same target. There may be a few reasons for this: target orientation, target depth, purity of metal, corrosion, ground mineralization etc.
TARGE T I D and I D MAS KI N G ROCK IRON NON-FERROUS Brown Area: Hot rocks Blue Area: Ferrous metals, iron rocks, salty and alkali soils Yellow Area: Copper, brass, aluminum, silver, gold, some hot rocks etc. This data may vary based on the field conditions. It may take some time and experience to utilize the Target ID feature in your search area because Target IDs as well as the depths the IDs are generated by different brands and models of detectors are also different.
PI NPOI NT Pinpointing is to determine the center or the exact location of a detected target. FORS Tech operates on the principle of motion. This means that you must move the search coil over the target or the target over the search coil, in order for the device to detect it. In the pinpoint mode, however, the device constantly gives signal when you hold the search coil still over the target. A proper ground balance setting is a must for accurate pinpointing.
DEP TH I NDI C ATI O N The device gives an estimated depth reading based on signal strength in the pinpoint mode. When the pinpoint button is pressed and the target is approached, the depth reading will appear in ''cm.'' on the LCD panel and the numeric display simultaneously. Approximate depth is provided based on the assumption that the target is a typical modern coin. The real depth will vary based on target size.
MAGNE T I C MI NER ALI Z ATI O N L E V EL Magnetic Mineralization level ranges from 0-99 and is 76 displayed in the Magnetic Mineralization Indicator on the Target right side of the main screen. This measurement can be ID summarized as the amount of the magnetic property and intensity of the ground. Simply, if you are working on a GEN General Search ground with intense and magnetic minerals, this value will be high. If the ground has low magnetic intensity, this value will be small.
E F F E C TS OF HOT ROC K S I N GRO UN D TR ACKI N G When the ground tracking is active, the device may give a warning tone and ID when it passes over a hot rock because the effect of the hot rock will be different than the ground's. If you sweep the search coil over the rock, ground tracking will automatically adjust the setting and the warning tone/ID will either disappear or diminish significantly.
MESSAGES At the bottom of the LCD panel, on the main screen, messages will appear if any. If there is no message, the present search mode name will be displayed. Messages that may appear are as follows: OVERLOAD: It appears simultaneously with the overload warning alarm sounding like a siren. This happens when the search coil encounters a shallow or a very large object. The device will revert back to normal operation if you lift the coil up.
FAC TORY and STARTUP S E T TI N GS The technical settings of the device (Mode, Ground Balance, Sensitivity, Threshold, and ID Masking, Frequency) come with their factory default values at each startup. Personal settings (Volume, Tone, Vibration, Brightness, and Language) come with the last adjusted value when the device is turned off and on again.
