OUTDOOR OPERATION

Metal detectors are primarily intended for outdoor use. Do not use the detector near sources of power or places with a lot of metal. Field detection may also be complicated due to soil conditions, size, shape and oxidation of metals. The more you practice, the more experienced you will become, and will thus get better and more accurate results.

(1) Turn on the device

After pressing the POWER button, the detector will beep twice and all screen icons will light up briefly. Once the detector is ready, it will return to the mode it was in before it was last turned off.

(2) Set the operating mode

Start with the mode ALL METAL. If a particular metal is desired, set the detector to one of the previously described modes. As soil conditions vary, it is sometimes a good idea to take samples of certain metals, bury them, and then adjust the settings of the detector for the most accurate results possible. Using the PINPOINT mode can also help increase accuracy and indicate soil contamination.

(3) Adjust sensitivity

The lower the sensitivity, the more accurate the results will be. However, in soils that contain many minerals, this can also lead to undesirable results. Adjust the sensitivity to get the best results for this type of soil. When working near another person using a metal detector, stay at least 10 meters apart so as not to interfere with each other's results.

(4) The right pattern of motion

Try to maintain a steady pace of swinging. Jerky movements may prevent the detector from being able to probe the ground quickly enough. Hold the search coil parallel to the ground, not at an angle. Move in a constant slow motion.

(5) Metal detection by pitch

With detection, sound is sometimes more helpful than looking at the screen. There are four pitches that will help you recognize what kind of metal has been discovered:

• Low pitch: ferrous metals such as iron, lids, etc.
  • Medium-low pitch: pull tabs, 10-pence nickel coins, etc.
  • Medium pitch: can tabs, 1 and 2-pound coins
  • High pitch: copper, aluminum, silver, etc.

(6) Pinpoint

While in motion mode, it is possible to locate something metallic, but the exact location can be difficult to find. After something has registered on the detector, switch to PINPOINT mode to get the exact location.

- Press and hold the PINPOINT button and the PINPOINT indicator will light up. The coin depth indicator shows [8+]. The upper and lower scale displays will all go out. The detector will emit a deep tone. If the displays do not go out, release the PINPOINT key and try again.

- Once in PINPOINT mode, move the search coil slowly near the object until a high signal strength indicates the exact position. Once the position is determined, the sound will become louder and the target depth indicator will brighten.

- Hold the detector firmly in this position and release the PINPOINT key. Press the button again after a few seconds. The indicator will go off and a single low tone will sound. Move the search coil slowly around the target until the sound becomes louder and the depth indicator brightens again.

- Repeat this process several times until the exact position and depth are known.

- When a depth of 2-4" is displayed, the subject is close to the center of the search coil.

- Note: In PINPOINT mode, the depth indicator becomes the signal strength indicator at the same time.

(7) Adjust ground balance

Before using the PINPOINT mode, use the ground balance button to adjust the detector. This helps to eliminate minerals in mineral-rich soils.

• Find a metal-free area of the soil. Set the ground balance setting to [P].

- Lift the search coil more than a meter above the ground (see picture). Press the PINPOINT button and bring the coil to about 1.5 cm above the floor.

GND BALANCE P DEPTH

• If both the signal frequency and the signal strength show no obvious change, the ground balance is already set.
• If there is an obvious change when approaching the ground, then you need to adjust the ground balance.
• Raise the search coil again and turn the ground balance knob 15 degrees clockwise.
• Press the PINPOINT button again and bring the coil to about 1.5 cm above the ground.
• If there is an obvious change again, repeat the process until the ground balance is set and there is no major change when lowering.
• Adjust the ground balance slowly so as not to over-adjust and reduce the sensitivity.
• Note: In heavily mineralized or magnetic soils, it may be difficult to achieve the correct ground balance.

(8) Depth and destination

• The five modes selected with the MODE button are all motion modes. They indicate a rough metal type, depth and location.
• When the position and type of metal of the object are detected, a repeated beep will sound. If this is not the case, it could be an incorrect target, a waste metal or a heavily oxidized object.
• Once a metal object has been found, the upper scale arrow will indicate the type of metal. The results will be more accurate in neutral soil than in heavily mineralized soil.

- Smaller, thinner gold objects show a result comparable to the 10 pence coin, while larger gold pieces point to the can tab or the 1 pound coin. The largest will be displayed only if the object is at least as large as a 2-pence coin.

- Silver is displayed on the right, and the larger the item, the farther to the right it will appear.

- The depth display for coin-sized objects is very accurate. Larger, irregularly shaped objects may vary in reading. In this case, repeatedly crossing the same area can lead to better results. If the depth display still varies, more than one object may be detected.

- As already mentioned, in unknown areas, the detector will show different results depending on the soil type and composition of the found objects. Certain types of metals may need to be eliminated to avoid missing metals.

(9) The use of non-motion mode

This is the most responsive type of detection. In heavily mineralized soils or in confined spaces, PINPOINT mode may be the best choice for object detection. Move the search coil slowly in PINPOINT mode.
