ABOUT YOUR FISHER 1270 The 1270 is a “motion” detector and was designed to offer you more versatility in a wide range of conditions: Highly mineralized soil, extremely trashy areas, and deep targets. By utilizing the various controls on the 1270, you will find more items that were unreachable until today. We at Fisher Research Laboratory always strive to give you maximum performance and quality, and have been doing so since 1931.
CONDENSED OPERATING INSTRUCTIONS We recommend that you first read this entire operating manual before taking your new 1270 out for a test drive. You’ll be more successful, and have a better chance of finding more treasure. But, we also understand the excitement of the “hunt”, so here are some simple instructions for setting up the 1270. Set the controls as follows: NORMAL DISC = 5 (iron & foil discrimination) SILENCER switch = ON IRON DISC switch = OFF ALL METAL GROUND ADJ.
Figure #1 SETTING UP Your new 1270 comes ready to assemble and use, but first review the steps below before proceeding. STEP 1. Unpack your 1270 carefully, and save the carton: It may come in handy on the rare occasion that you may need service. STEP 2. The coil is attached to the lower stem. Depress the spring lock button on the lower stem, and slip it into the center handle section until it snaps into a hole. STEP 3.
SETTING UP STEP 6. When the stem length is properly adjusted, tighten the lower lock nut, and the coil wing nut. CAUTION: Never use a pliers or anything other than your hand to tighten either lock nut or wing nut. STEP 7. Disconnect the search-coil cable from the control housing and wrap it around the stem. 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 search coils. Reconnect the search coil cable to the control housing.
CONTROLS & FUNCTIONS 1. ON / OFF VOLUME: ON /OFF VOLUME: Allows you turn on the 1270 and adjust the volume to a comfortable level. No need to have a special headphone with volume controls. Turning this control clockwise adjusts the volume. 2. NORMAL DISC: When operating in NORMAL DISC mode, this control gives you the ability to adjust the rejection point of the 1270 to a wide range of metal objects. At lower settings, the 1270 will reject most ferrous and low-conductivity metal objects.
CONTROLS & FUNCTIONS 7. IRON DISC TOGGLE: When this toggle switch is flipped ON, the 1270 will operate in IRON DISC mode. When operating in this mode, the IRON DISC control becomes active and the NORMAL DISC control will be ignored. The NORMAL DISC control can be momentarily re-engaged without changing the IRON DISC setting by pushing the MODE TRIGGER switch forward. 8. SILENCER: Used in conjunction with the NORMAL DISC control, this feature reduces the normal clicks and pops heard while going over trash.
CONTROLS & FUNCTIONS > PRIMARY AND SECONDARY OPERATING MODES A “primary” operating mode is active when the MODE TRIGGER switch is in the Normal (center) position, and the “secondary” operating mode is active when the MODE TRIGGER is in the Swap position (pushed and held). The following front panel settings will show you how to achieve your favorite primary and secondary operating modes. This will allow you to quickly change modes without losing any settings to gain more information about your targets.
ALL METAL MODE metal. This may be tested quickly by pulling the trigger switch and sweeping over an area of about one square foot. If no signal is detected, release the trigger switch and raise the search coil off the ground, and lower it back down two or three times (also known as “bobbing”). If an audible sound is heard, turn the GROUND ADJUST knob slightly clockwise. Repeat this procedure until no sound is heard when raising and lowering the coil to the ground.
NORMAL DISC MODE When rejection of a full range of other non-ferrous trash is desired, the NORMAL DISC mode will be necessary. Make sure the ALL METAL GROUND ADJUST is OFF; that is, fully counterclockwise until it “clicks” into the “0” position. The IRON toggle switch must also be OFF. Adjust the NORMAL DISC knob to reject the unwanted “trash” targets (see figure 2). When the NORMAL DISC is set at “0”, all metals will be detected. As you turn the NORMAL DISC knob clockwise, certain metals will be rejected.
SEARCH TECHNIQUES Good searching techniques are every bit as important as having a good detector. 1. Adjust your SENSITIVITY control. Only experience will tell you how to set it in every situation. As general rule, turn up the sensitivity to achieve maximum depth and detection of small items. You will also get a wider search scan.
SEARCH TECHNIQUES NO- MOTION PINPOINT 1. When the target “beep” is heard, make an “X” over the target, as described above, to determine the target area. 2. Move the coil away from the target area, and lower the coil to the ground. 3. Pull, and hold the MODE TRIGGER switch. 4. Raise the coil about 1/2 inch; move back across the target area. 5. Stop the coil at the center of the loudest response. 6. Repeat this one more time, moving your coil from side to side.
TARGET RECOVERY Once you have pinpointed a target, your objective is to recover it quickly and neatly, leaving virtually no trace of your excavation. There are many ways do this, and you will soon discover which method works best for you. REMEMBER: Always leave the ground in the same condition as you found it. NEVER leave exposed holes or damage to vegetation. RECOVERY TOOLS 1. Many Detectorists use a heavy-duty blunt screwdriver. An expert with this method can leave virtually no trace of their recovery. 2.
FALSE SIGNALS A “False Signal” occurs when something sounds like a good target, but is not. Your 1270 does a great job of discriminating, but bad “targets” with similar electrical characteristics can fool it. Large pieces of trash or items very close to the search coil will occasionally sound “good”. Experience is the best teacher. As you accumulate more hours with your 1270, you will soon learn how to distinguish “false signals”.
MAINTENANCE: Your 1270 doesn’t require a lot of care, nor does it require regular “maintenance”. However, you should do a few things to keep your 1270 in peak operating condition. 1. Remove the batteries if you’re not going to be using your detector for a while. Batteries can leak, and cause severe damage. 2. Avoid extreme temperatures. When parked in the sun, never leave your detector in a closed car or in the trunk. 3. If you “scrub” your detector coil on the ground, you will eventually wear through it.
