Wireless Technology: Z-Link Changes the Game
When you’re hunting in remote terrain, the last thing you need is audio lag compromising your target signals. Z-Lynk technology delivers 17-millisecond latency—six times faster than Bluetooth and up to four times quicker than competing wireless systems.
Z-Lynk’s 17-millisecond latency outperforms Bluetooth by six times, ensuring you never miss critical target signals in the field.
This near-instantaneous transmission guarantees you’ll catch every nuance of your detector’s audio response.
The frequency-hopping protocol operates across the 2.4 GHz band, creating unlimited channels that eliminate interference from nearby detectors. You’ll maintain a reliable connection even in crowded hunting sites.
Battery lifespan extends to 30 hours per charge, with automatic shutoff preserving power during breaks. The system recharges via standard USB connections, allowing you to power up from laptops, vehicle ports, or phone chargers during extended field sessions. A battery indicator LED alerts you when approximately three hours of power remain, preventing unexpected shutdowns in the field.
The wireless range supports unrestricted movement across challenging landscapes, while factory-paired modules work immediately with compatible Garrett models or through the optional WT-1 transmitter for legacy detectors.
Display Readability in Challenging Conditions
How well can you identify targets when sunlight glares off your screen or mineralized soil floods your display with noise? Display glare compromises the Manticore’s screen readability in bright conditions, forcing you to rely on audio signals when reflections obstruct your VDI scale readings from 0-99.
Mineral interference creates additional challenges—ground mineralization readouts continuously affect depth perception while bar graphs show concentration levels that can mask weak target signals. You’ll need to adjust sensitivity settings carefully, as maximum levels above 90 amplify internal circuit noise and clutter on mineralized ground. Consistent, solid tones indicate promising targets even when visual display becomes difficult to read, while broken or noisy audio patterns typically signify junk items. High-pitched tones suggest shallow targets near the surface, whereas lower-pitched sounds indicate deeper buried objects that may require adjusting your digging strategy.
The menu-driven interface remains accessible in inclement weather, but cold wet conditions risk screen damage and bubbling. Environmental factors like power lines cause erratic display behavior, requiring sensitivity reductions to minimize constant interference alerts while maintaining target detection capability.
Ground Balance Performance in Difficult Soils
Ground balance systems separate genuine metal targets from mineralized soil interference through continuous signal processing that compares ferrous and conductive ground properties against your detector’s baseline settings.
You’ll encounter soil conductivity variations that demand different approaches—saltwater beaches require frequent rebalancing against conductive minerals, while rocky terrain needs adjusted parameters to eliminate stone interference. Mineral interference escalates in highly mineralized ground, causing excessive noise and depth loss without aggressive settings.
The AT Pro’s manual ground balance lets you customize precisely for specific mineralization levels, while the AT Max adds automatic tracking that continuously adapts as you sweep across changing conditions. Wet soils force sensitivity reductions unless you’ve dialed in exact balance. Proper ground balance removes false signals from ground salts and minerals that would otherwise obscure legitimate targets.
Your freedom to hunt anywhere depends on mastering these soil-specific adjustments that restore target separation and detection depth. Ground balance calibration should occur at the beginning of every detecting session and whenever you move to different terrain within your hunting site.
Audio Systems: Threshold Control and Iron Discrimination
You’ll find the AT Pro and AT Max share similar iron discrimination features through their Iron Audio modes in disc settings, but neither offers the dedicated threshold control found on the ATX’s 25-level adjustment system.
The ATX’s threshold control lets you fine-tune the constant background hum independently from target signals, while the Pro and Max rely on volume controls that affect all audio output equally.
Your iron identification capabilities remain comparable across both models with 5-tone target ID and Iron Audio, though you’ll sacrifice the ATX’s specialized Iron Check feature that produces distinct ferrous growls. The ATX’s pulse induction technology provides enhanced stability in mineralized environments that both the Pro and Max models cannot match with their VLF detection methods. The ATX operates at 730 pulses per second, delivering rapid target response that can be adjusted to match your hunting conditions.
Iron Audio Mode Differences
One critical distinction separates the AT Pro and AT Max iron audio implementations: mode availability. Your AT Pro restricts Iron Audio to discrimination modes only, leaving All Metal mode without this capability.

Battery life remains consistent between units, but the AT Max’s proportional-only system demands practice for mastery in iron-contaminated sites. The AT Max provides adjustable threshold settings that enhance your ability to customize audio response, while the AT Pro lacks this threshold control feature.
The AT Max includes a headphone output for audio signal monitoring, supporting standard mini-jack connections for enhanced detection clarity.
Volume and Threshold Controls
While both detectors share identical volume and threshold architectures, mastering these controls transforms your ability to hear faint targets in challenging terrain. Adjustable volume caps loud signals from oversized objects without sacrificing sensitivity to small targets—you’ll reduce can-sized blasts while maintaining gold ring detection.
Threshold tuning operates independently, establishing a barely audible background hum that guarantees weak signal breakthrough from depth. Set your threshold between negative 9 and 25, positioning it at barely audible levels for perfect performance.
This constant audio baseline breaks or blanks over discriminated iron, giving you instant feedback on rejected targets. Combined with full sensitivity settings, proper threshold tuning delivers measurable depth advantages in mineralized soils where freedom-seekers chase elusive gold nuggets and deep relics.
Saltwater Beach Detection Capabilities
Saltwater beach environments present significant operational challenges for VLF single-frequency detectors like the AT PRO and the AT MAX.
The conductive nature of salt water amplifies ground mineralization and produces false signals that don’t occur in freshwater conditions.
