You’ll need to master three core systems on your Teknetics G2 Plus: the GROUNDGRAB automated ground balance, the V-Break tone discrimination (typically set between 35-40), and the 99-position sensitivity control. Start by wrapping your coil cable with slack near the connection, install a 9V battery, and activate through the POWER/GAIN knob. Your LCD displays target IDs from 0-99, where values below 40 indicate ferrous materials. The thorough guide below explains advanced calibration techniques for mineralized soils and saltwater beaches.
Key Takeaways
- Install 9V battery, wrap coil cable with slack near coil, and turn POWER/GAIN knob clockwise to activate detector.
- Use GROUNDGRAB for automatic ground balancing to eliminate false signals and maximize detection depth in mineralized soil.
- Set V-Break Tone between 35-40 to distinguish ferrous targets (below 40) from non-ferrous targets (40 and above).
- Adjust sensitivity to 85-100 in normal conditions or reduce to 70-75 in heavily mineralized or iron-rich environments.
- Use Static All-Metal Pinpoint mode with VCO audio and LCD depth indication for precise target location.
Understanding the G2 Plus Components and Specifications
The Teknetics G2 Plus operates on VLF (Very Low Frequency) induction balance technology at 19-19.2 kHz, utilizing quartz crystal timing for frequency stability. This frequency excels at detecting small, low-conductivity gold nuggets while maintaining versatility for coins, jewelry, and relics. Your standard equipment includes a waterproof 7×11-inch BiAxial Double-D coil optimized for relic hunting in mineralized soils.
Coil exchange considerations become important when you’re switching between applications—the optional 5-inch DD coil dramatically improves target separation and gold prospecting performance. The control system features 99 sensitivity levels, adjustable threshold (-40 to +40), and V-Break tone discrimination (0-80). You’ll monitor ground conditions through continuous Fe3O4 mineralization displays and ground phase readouts. The GROUND GRAB computerized system balances across 0-99.9 range, handling everything from ferrite to saltwater environments. Overall detector handling benefits from the backlit LCD showing 2-digit VDI numbers and 7-bar signal strength indicators.
Setting Up Your Detector for First-Time Use
Before field deployment, you’ll need to complete several critical configuration steps that establish baseline detector performance. Start by wrapping the coil cable around the stem with adequate slack near the coil, then securely connect it to the control housing receptacle. Install a 9V battery following polarity markings in the rear compartment.
Turn the POWER/GAIN knob clockwise to activate, noting the three-bar battery indicator when fully charged.
Power on considerations include testing initial gain settings in your actual operating environment before extensive detecting. Most operators maximize gain (0-100 range) for ideal depth penetration. However, gain reduction strategies become essential when encountering excessive noise or instability—particularly in heavy iron soil conditions where settings between 70-100 work best alongside discrimination values of 32-39.
Mastering GROUNDGRAB and Manual Ground Balance
Ground balancing represents the most critical calibration step for achieving ideal depth penetration and target identification in mineralized soil conditions. The GROUNDGRAB system offers one-touch automation—hold the GG/MENU button while pumping your searchcoil vertically from 6 inches to 1 inch above clear ground until the display stabilizes.
For troubleshooting ground balance issues near power lines or electromagnetic interference, switch to manual mode. Rotate discrimination to zero, maximize sensitivity, and adjust threshold to barely audible. Lower your coil from 10 to 4 inches while monitoring pitch changes. Turn the GB knob two full rotations right if humming increases, then reset. Repeat until pitch remains constant.
Soil specific calibration eliminates false signals and maximizes detection depth in challenging terrain exceeding 10,000 micro-cgs units magnetic susceptibility.
Configuring the V-Break Tone Discrimination System
The V-Break function establishes a frequency threshold that splits your detector’s audio response into distinct low and high tones based on target conductivity values. You’ll access this setting through the menu system and use plus/minus buttons to adjust the breakpoint value—typically between 35-40 for general hunting—where targets below the threshold produce low tones while those at or above generate high tones.
This tone separation mechanism works in coordination with your discrimination settings to help you distinguish ferrous iron signals from non-ferrous targets worth digging.
Understanding V-Break Basics
V break optimization depends on hunting conditions: set 35 for gold detection to capture marginal signals, 39-40 for relic hunting to separate iron from non-ferrous targets, or 40 for field scanning. The system functions even in zero discrimination mode, maintaining maximum sensitivity while providing audible target classification.
You’ll hear iron pops at reduced volume alongside clear high tones for desirable finds—no signal loss, just intelligent audio separation.
Adjusting Breakpoint Settings
To configure your detector’s tone discrimination, press the menu button three times until the V-Break screen appears. Use the plus and minus buttons to adjust the numerical value across a 0-80 VDI span. V break range optimization depends on your hunting environment and target priorities.
Field-Tested Configurations:
- Gold Priority: Set V-Break at 35 with discrimination at 0, sensitivity 85-95, and gain 99-100 for maximum depth on low-conductors reading up to 40 VDI.
- Park Mode: Raise V-Break to 40 to reject foil while retaining nickels; pair with discrimination 32-39 in heavy iron zones.
- Volume Settings Integration: Configure volume at 14 (non-ferrous 10, ferrous 4) or 13 (non-ferrous 10, ferrous 3) to distinguish faint target tones effectively.
Keep notch at 0 to avoid interference with your V-Break discrimination.
Optimizing Tone Responses
Enable V.C.O. audio in all-metal mode for pitch-based feedback that rises with target strength.
In discrimination mode, combine notch settings with adjustable notch width to eliminate specific conductivity ranges while maintaining distinct tones for accepted targets.
This configuration excels in iron-infested sites, beaches, and mineralized soil, providing the audio clarity you need for confident, independent hunting decisions without unnecessary signals restricting your freedom.
Using FeTone for Iron-Heavy Environments
When you’re hunting in iron-contaminated sites, FeTone transforms the G2+ into a sophisticated audio filter that lets you hear iron signals as distinct low buzzes while non-ferrous targets produce clear high tones. This adjustable iron tone feature operates at 19 kHz, providing exceptional ferrous signal audibility even in mineralized ground.
Volume Configuration Strategy:
- Scale 10-20: Set non-ferrous maximum at 10, with remaining points controlling iron volume (example: 14 = ferrous at 4)
- Heavy Iron Fields: Use 15-20 settings to maintain awareness without audio overload
- Discrimination Integration: Run disc at 0 with FeTone for maximum depth while maintaining iron awareness, or disc 32-39 in heavy contamination
Confirm suspected iron by tipping your coil forward—genuine iron produces characteristic buzz versus false high VDI readings when detecting flat.
Reading the LCD Display and Target ID Numbers
The G2 Plus LCD provides real-time target identification through an all-encompassing numeric readout spanning 0-99, where each number represents the conductive signature of objects beneath your coil. Reading the LCD display requires understanding that values below 40 signal ferrous or low-conductive materials, while numbers 40 and above indicate high-conductive non-ferrous targets like coins and jewelry.
When reviewing target ID numbers, stable consistent readings confirm reliable signals, whereas fluctuating values suggest ground mineralization interference. Cross-reference the numeric display with audio tones for precise identification.
The 3-segment battery indicator at top-left monitors power status—three segments mean full charge, one segment warns of depleted power requiring alkaline 9V replacement. In discrimination mode, you’ll see rejected segments alongside active ID numbers, while All Metal mode displays the complete 0-99 range without restrictions.
Selecting the Right Operating Mode for Your Hunt
You’ll need to master the G2 Plus’s two primary operating modes to match your detector’s capabilities to field conditions. Discrimination Mode filters unwanted targets in trash-heavy sites through conductivity-based rejection, while All-Metal Mode delivers maximum detection depth by processing signals through a single filter without discrimination.
The V.C.O. (Voltage Controlled Oscillator) audio feature in All-Metal Mode provides variable pitch and volume responses that help you interpret target size and burial depth before you dig.
Discrimination Mode for Trashy Areas
How can you maximize depth and target separation when detecting in trash-laden sites? Set discrimination to zero for complete target recovery strategies, allowing you to hear all signals while using V-Break tone separation to distinguish valuable finds from iron. This discrimination threshold adjustment maintains full depth without false rejections.
Configure your G2 Plus with these critical parameters:
- V-Break at 35-39: Low tones indicate ferrous targets; high tones signal non-ferrous items worth digging
- Volume Balance: Set non-ferrous at 10, ferrous at 3-4 to reduce iron chatter while preserving weak signal audibility
- Sensitivity 85-100: Run maximum gain in disc mode; drop to 70-75 only in extreme trash conditions
This setup liberates you from arbitrary target rejection, giving you complete control over what you dig based on repeatable high-tone responses.
All-Metal Mode for Maximum Depth
Switching to Motion All-Metal mode reveals your G2 Plus’s absolute maximum sensitivity depth—critical when you’re targeting deep silver coins, small relics, or anything buried beyond 8 inches in challenging ground. This mode bypasses discrimination circuitry entirely, allowing full signal transmission from ferrous and non-ferrous targets alike.
The 19 kHz frequency excels at detecting tiny hammered coins and thin low-conductivity artifacts that discrimination might miss. Engage GROUNDGRAB for efficient ground tracking in mineralized soil—the continuous phase readout and Fe3O4 graphic show exactly what you’re dealing with. Manual fine-tuning eliminates false signals that rob depth.
VCO audio provides instant target sizing cues, while the static pinpoint with depth indicator confirms precise location before digging. Maximum depth demands All-Metal mode—discrimination trades reach for selectivity.
VCO Audio for Target Sizing
The Teknetics G2 Plus’s Voltage Controlled Oscillator (VCO) audio system transforms raw signal strength into proportional pitch and volume changes, giving you real-time target sizing data before you ever glance at the display. This audio architecture enables precise target size quantification through acoustic signatures alone, liberating you from constant screen monitoring.
Optimizing audio response requires strategic configuration:
- Discrimination VCO: Deploy V-BREAK at 40+ for park hunts, isolating ferrous trash while maintaining tonal clarity on non-ferrous targets
- FeTone Integration: Set iron volume (10-20 range) to suppress 0-40 ID ferrous signals without masking adjacent good targets
- Threshold Tuning: Adjust -40 to +40 range to establish baseline hum, ensuring weak signals from small or deep objects break through ambient noise
Combined with 19 kHz frequency sensitivity and 99-segment Target ID, VCO delivers complete target characterization without visual dependency.
Pinpointing Targets With Depth Estimation
Once you’ve located a target in discrimination mode, activating the G2 Plus’s Static All-Metal Pinpoint mode allows you to determine its precise location and estimated depth. Switch to All-Metal mode to engage VCO audio feedback—you’ll hear pitch variations that intensify as you approach the target’s center. Move your coil horizontally until detecting the highest pitch, then sweep vertically for confirmation. The LCD displays depth in 1-inch increments, with the lowest number appearing at target center beneath the coil’s black dot indicator.
For maximum accuracy, analyzing target density indicators through signal strength bars (1-7) helps verify depth readings. Interpreting ground mineralization details via GND PHASE and Fe3O4 graphics provides essential context, since mineralization affects detection depth. Use X-pattern sweeps to narrow your pinpoint precision effectively.
