INSTRUCTION MANUAL QUEST AMD

READ CAREFULLY BEFORE OPERATION OF THE DEVICE

Comply with applicable laws and regulations governing use of metal detectors while using this detector. Do not use the detector without authorization in protected or archeological sites. Do not use this detector around unexploded ordnance or in restricted military zones without authorization. Notify appropriate authorities with details of any historical or culturally significant artifacts you find.

WARNINGS

The Quest Air Metal Detector is a state-of-the-art electronic device. Do not assemble or operate the device before reading the user manual.
To avoid affecting after-sales service, please refrain from disassembling the circuit of the lower rod arbitrarily.
Do not store the device under extremely low or high temperatures for extended periods. (Storage Temperature: -20°C to 50°C)
The device has been designed with IP68 rating as a waterproof unit up to 1 meter.
Pay attention to the items below after using the device especially under salty water:
- Wash the rod and the coil with tap water and be sure no salt water is left in the connectors.
- Do not use any chemicals for cleaning and/or for any other purposes.
- Wipe the rod dry with a soft, non-scratch cloth.
Protect the detector against impacts during normal use. For shipping, carefully place detector in original carton and secure with shock resistant packaging.
The Quest Air Metal Detector may only be disassembled and repaired by Quest Authorized Service Centers. Unauthorized disassembly/intrusion into the metal detector control housing for any reason voids the warranty.

IMPORTANT!

Do not use the device indoors. The device may constantly give target signals indoors where there are many metals present. Use the device outdoors, in open fields.
Do not let another detector or an electromagnetic device come in close proximity (10m (30ft.)) to the device.

EU Declaration of Conformity

Hereby, Dongguan Quest Detection Technology Co., Limited declares that this radio equipment is in compliance with directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following address: www.detectorportal.eu/compliance. The product is marked with CE and RoHS (2011/65/EU) compliance symbols.

Setup

Assembly

The assembly involves connecting the lower rod with the coil to the middle rod, and then to the upper rod. The handle is attached to the upper rod and secured with a locking lever. The armrest is attached to the bottom of the upper rod and tightened with a screwdriver.

Diagram shows the lower rod with coil, middle rod, upper rod, handle, and armrest being assembled.

Holding a Phone

The phone holder clamp can be pulled open to accommodate a phone. It can be rotated for horizontal (recommended) or vertical orientation. Once the phone is placed, the clamp secures it. The holder can be folded away or removed entirely, with a handle cover provided to fill the gap.

Diagram shows the phone holder clamp being opened, a phone being inserted, and the holder being attached to the handle.

Storage

The Quest Air can be flat-folded for compact storage by pulling out the lower rod, rotating it 90 degrees, and inserting the middle rod.

Diagram illustrates the process of folding the metal detector for storage.

App & Connection

Mobile App Installation

Search and download the "QUEST AIR MD" application from the App Store or Google Play Store.

Icons for Google Play and Apple App Store are shown.

Smart Phone Connection

1. POWER ON: Activate the coil by pulling out the lower rod until it reaches the magnetic sensor. This action triggers the magnet, sending a signal to the magnetic sensor to power on. (After the coil is connected with the app, you may adjust the length of the lower rod as needed.)

2. Bluetooth & GPS: For Android, enable Bluetooth and GPS in settings; for iPhone, enable Bluetooth.

3. Launch the Quest AIR MD app.

4. Search for the Quest Air detector in the App. In the Bluetooth device searching list, locate and select "QuestMD-V2.4". If not found, ensure Bluetooth and GPS are enabled, and verify the correct placement of the lower rod. Press "Scan" in the middle of the screen to resume Bluetooth device scanning.

5. Wait for the coil to establish a connection. If the coil fails to connect, close the application, turn off Bluetooth (or reboot the Android device), or adjust the lower rod placement, then retry from step #3&4. To disconnect the coil from the app, simply press the power button located in the upper right corner of the app. Once disconnected, the coil will be deactivated.

Screenshots show the "Connect Device" interface with a "Searching..." status and a "Try again" button.

Settings

SENSITIVITY (1-50)

Sensitivity: The higher the setting, the more your detection depth increases. Caution: High sensitivity may result in more false positives and unstable signal quality.

DISCRIMINATION (-90 to 90)

Unwanted metals discrimination. Below zero indicates iron, while above zero indicates non-ferrous metals.

RECOVERY SPEED (0-10)

Increasing the recovery speed improves metal detection in cluttered areas. However, it reduces detection depth and raises the minimum coil swing speed above targets.

TONES (1...4, FAST)

The number of tones corresponds to various metals. In FAST mode, there's the maximum number of tones and maximum speed.

THRESHOLD TONE (0-10)

A permanent background tone aids in discriminating between wanted and unwanted targets. This feature is only available in FAST mode for the "TONES" setting.

HOT ROCKS (0-10)

Suppresses signals from hot rocks. Highly mineralized soils with hot stones can cause false positives with signal strength above 85. Raise the setting until signal strength from hot rocks becomes comfortable to work with. Setting it too high may reduce detection ability for large silver coins.

Charging

Before first use, it is recommended that you fully charge the battery for 6 hours. Use a high-quality mobile phone charger plug to charge the detector. The specific steps are as follows: Detach the lower rod and unscrew the orange protective cap of the detector. Insert the larger end of the charging cable into a socket or a computer with a standard plug, or a solar power bank, and insert the smaller end (Type-C) into the metal detector plug.

Charging typically takes between 5 to 6 hours. Need to check the app for the charging status. Once fully charged, the battery can operate for approximately 10 hours.

Diagram shows various charging methods: USB-C cable connected to a computer, power adapter, and a solar power bank.

Detecting

1. Swing the coil: Maintain the coil about 4cm above the ground and ensure that swings overlap to cover the area thoroughly.

2. Activate Pinpointer: Upon hearing a distinct tone, press the PINPOINTER button in the app and move the coil in a crisscross manner (XING) to pinpoint the target accurately.

3. Utilize the Pinpointer: Employ a pinpointer to precisely locate the target's position.

4. Digging Process: Use the digging tool to expose the target gradually. Ensure you excavate thin layers of soil to avoid missing any items, periodically checking with the pinpointer for accuracy.

Diagrams illustrate the four steps of detecting: swinging the coil, using the pinpointer, locating the target, and digging.

Trouble Shooting

1. Cannot find Quest AIR Metal Detector in App

Check Coil: Ensure that the low rod is properly extended. Try retracting and extending the lower rod to the right place again.

Check App: Make sure Bluetooth and GPS settings are enabled.

2. The Audio response is slow

Keep Close: Maintain the phone within 10 meters of the handle/coil for prompt audio feedback; the closer, the better.

3. Too Much Noisy Sound

Move Away: Keep distance from electronic devices or power lines.

Balance It: Perform a Ground Balance automatically or manually.

Lower Sensitivity: Turn down the Sensitivity setting.

4. No Sound with Wireless Headphones

Check Headphones: Make sure they are powered on.

Activate Wireless: Ensure the detector's wireless function is enabled and paired with your phone.

Charge Headphones: Make sure they are fully charged.

Volume: Check both the headphone and your smartphone volume settings.

Try Wired: If all else fails, try wired headphones with your phone.

5. Disconnection with App

Check battery status: Check the coil battery status on your phone.

Check coil: Avoid submerging underwater beyond 50cm.

Reconnect: Reconnect the coil with the App as per the instruction on Page 4.
