Minelab Vanquish 340 Metal Detector User Manual
Official guide for operating and maintaining your Vanquish 340.
Quick Start Guide
Get started with your Minelab Vanquish 340 in three simple steps:
- Turn On the Detector: Press the power button.
- Wait 5 Seconds: Allow the detector to initialize.
- Start Detecting: Select your desired search mode and begin.
Search Modes
The Vanquish 340 features 3 preset search modes, each with a different discrimination level, to help you find more targets.
? Coin Mode
Detects most modern coins while rejecting common iron trash found in parks and beaches. This mode offers excellent selectivity, ensuring you don't miss good targets near iron pollution. Discrimination implies a total rejection of iron objects and some small non-ferrous items like aluminum fragments.
? Jewellery Mode
Find precious jewelry regardless of where it was lost. This mode provides excellent selectivity and depth, making it a versatile choice. It's particularly recommended for finding jewelry of all shapes, sizes, and alloys. Discrimination rejects only iron objects.
⚙️ All Metal Mode
Detects all metallic targets, including iron. This mode ensures you won't miss any target, though it may result in finding more trash. Discrimination is set to detect all objects, ferrous or non-ferrous. The tone is adjusted so small non-ferrous targets may sound like iron trash (see page 9).
Buttons and Settings
Familiarize yourself with the control panel:
The control panel features a display screen, several buttons, and indicators. Key elements include:
- 1. Power Button: Turns the detector on and off. A long press (7 seconds) from the off position resets the detector to factory settings.
- 2. Volume Button: Adjusts the audio volume.
- 3. Sensitivity Button: Adjusts the sensitivity level.
- 4. Search Mode Button: Selects the desired search mode.
- 5. Conductivity Scale: A reference guide indicating target types based on their numerical identification (ID).
Display Indicators
The display provides essential information about your detection session:
The display screen shows various indicators:
- 1. Battery Level: Indicates the current battery charge.
- 2. Volume Level: Shows the selected audio volume.
- 3. Sensitivity Level: Displays the current sensitivity setting.
- 4. Target ID Number: A numerical value (from -9 to 40) that helps identify the target's composition. Negative numbers typically indicate iron, while positive numbers indicate non-ferrous targets (e.g., a US 25-cent coin usually reads ID 29). This ID remains on screen for 5 seconds or until a new target is detected. Two large dashes appear if no target is detected or if a rejected target is passed over.
- 5. Depth Gauge: Provides an approximate indication of the target's depth.
- 6. Search Mode: Shows the currently selected search mode.
- 7. Discrimination Segments: These segments represent groups of target IDs on the conductivity scale. They indicate which ID ranges are accepted or rejected by the current discrimination settings.
Detector Settings
Volume
The volume control adjusts the intensity of the audio tones. Press the volume button to increase volume. Once maximum volume is reached, it cycles back to the lowest level. A bar graph on the display indicates the selected volume level.
Sensitivity
The Vanquish detectors are highly sensitive and allow for sensitivity adjustment. Optimizing sensitivity based on ground conditions can improve detection depth. Always choose a sensitivity level that maintains stability for best performance.
Press the sensitivity button to increase the sensitivity level. Once maximum sensitivity is reached, it cycles back to the lowest level. A bar graph on the display indicates the current sensitivity level.
Setting Sensitivity
- With the coil still, increase sensitivity until false signals are heard.
- Reduce sensitivity just enough for the false signals to disappear. (If levels 2, 3, or 4 are selected, press three times to reduce by one level).
- Sweep the coil over clear ground (no metal targets) and reduce sensitivity if false signals persist.
False Signals
False signals can occur due to electromagnetic interference (EMI) from power lines, cell towers, or other detectors. If you experience false signals:
- Move away from potential EMI sources.
- Restart the detector and wait for the automatic interference reduction process to complete.
- If false signals continue, reduce the sensitivity level.
Automatic Noise Cancellation
The Vanquish detectors feature automatic noise cancellation that activates on startup. This calibrates the detector to avoid interference. For best results, keep the coil still above the ground until the process is complete (indicated by two large dashes on the ID display).
Pinpoint Mode
Locating a Target
Once a target is detected, Pinpoint mode helps you precisely locate its center before digging, saving time and effort.
- Slowly sweep your coil over the target, keeping it parallel to the ground.
- Listen for the loudest signal to identify the target's center.
- Memorize or mark the spot.
- Move to the side and sweep over the target at a 90-degree angle to your first sweep.
- Repeat steps 1 and 3 from new positions. The target's exact location is where the imaginary lines from your sweeps intersect.
The diagram illustrates the pinpointing process. First, sweep the coil over the target and trace a line where the signal is strongest (steps 1-3). Then, move 90 degrees from the initial position and repeat the sweep (steps 4-5). The intersection of these two lines indicates the precise location of the target.
Depth Gauge
The depth gauge provides an approximate indication of how deep a target is buried. Few arrows suggest a shallow target, while multiple arrows indicate a deeper one. Accuracy can vary based on target type and soil conditions. The gauge remains visible for 5 seconds after detection or until a new target is found. When no target is detected, the gauge and arrows are off.
Example display for a US 25-cent coin:
- 50 mm (2 inches): 1 arrow
- 100 mm (4 inches): 2 arrows
- 150 mm (6 inches): 3 arrows
- >150 mm (>6 inches): 4 arrows
Target Identification
Target ID Number
Target Identification (ID) numbers range from -9 to 40. Ferrous targets are typically indicated by IDs from -9 to 0. When a target is detected, its ID number appears on the screen, indicating its composition. For example, a US 25-cent coin typically registers an ID of 29. The ID of the last detected target remains on screen for 5 seconds or until a new target is detected. Two large dashes appear if no target is detected or if a rejected target is passed over.
The diagram shows a target ID of '29' displayed on the screen, with a segment highlighted on the conductivity scale, indicating a shallow US 25-cent coin. Another diagram shows two large dashes, indicating no target detected or a rejected target.
Discrimination Segments
These segments are located along the top border of the display and the conductivity scale. They group target IDs into distinct zones. Each numerical ID has a corresponding segment that will flash when a target with that ID is detected.
Discrimination / Search Modes
Discrimination segments can be activated or deactivated to accept or reject specific targets. Activated segments produce audio (accepted targets), while deactivated segments do not (rejected targets). Combinations of accepted and rejected segments form the search modes. The Vanquish 340 has 3 modes: Coin, Jewellery, and All-Metal (see page 9).
Diagrams show how discrimination segments are displayed for different modes. A checkmark (✔️) indicates an accepted segment, and a cross (❌) indicates a rejected segment.
- Coin Mode: Shows accepted and rejected segments for coin detection.
- Jewellery Mode: Shows accepted and rejected segments for jewelry detection.
All Metal Mode
In All Metal mode, all discrimination segments are active, meaning all metallic targets, including iron, will be detected. This mode ensures you don't miss any target, but it may also result in finding more iron trash. It can be useful for verifying if a target is ferrous or not.
Activating All Metal Mode
- Press the search mode button until the All Metal icon (e.g., a horseshoe ⛓️) is selected.
- All discrimination segments will activate, and all metallic targets will be detected.
- To exit All Metal mode, press the search mode button and select Coin or Jewellery.
Using All Metal Mode to Verify a Target
If a target provides a mixed response (both ferrous and non-ferrous) in All Metal mode, it might be a large iron object or a can. If a repeated non-ferrous response occurs, the target is likely non-ferrous. Note that large iron targets and cans are often misidentified as non-ferrous by other detectors; the Vanquish 340 is designed to detect them as trash.
Target Tones
Different tones are assigned to each discrimination segment, allowing quick target identification by sound. The Vanquish 340 offers 3 tones: Low (grave), Medium, and High (aigu). The tone break point is the conductivity scale position where the tone changes. These break points vary slightly between search modes.
A diagram shows the conductivity scale (-9 to 40) with approximate tone break points indicated for Low (Grave), Medium, and High (Aigu) tones.
Batteries and Charging
The detector accepts AA alkaline or rechargeable batteries. ⚠️ ATTENTION: Never mix rechargeable and non-rechargeable batteries, as this can damage the detector. Using an incompatible battery model may pose an explosion risk.
Battery Level
The battery indicator shows the current charge level. Note that rechargeable and standard batteries discharge at different rates, so the indicator provides an approximation.
Low Battery
If using standard batteries, the indicator will flash 20 minutes before automatic shutdown. With rechargeable batteries, a bar will disappear 20 minutes before shutdown. The indicator 'BF' will appear on screen with a specific sound 5 seconds before automatic shutdown.
With some rechargeable batteries, 'BF' may not appear before automatic shutdown.
Automatic Shutdown
When the battery level is critically low, the detector will automatically turn off.
Battery Life and Charging Time
- Minelab AA NiMH rechargeable batteries require 8 hours of charging for approximately 11 hours of use.
- Standard AA alkaline batteries provide approximately 10 hours of use.
Rechargeable Batteries
Minelab AA NiMH rechargeable batteries and chargers are available for separate purchase.
