Key Features

  • NEW Built-in Z-Lynk™ Wireless Technology: Cut the cord! Integrated circuitry transmits audio to your wireless headphones. Six times faster than Bluetooth speed! Auto pairing. No cables, and no interference from other wireless devices.
  • Maximum Detection Depth: Increased transmit power and enhanced electronics provides AT Max with significant depth increase.
  • True All Metal Mode: Detects all types of metal and provides the greatest possible detection depth and sensitivity.
  • Backlight: Illuminates LCD screen for improved visibility in low-light situations.
  • High Resolution Ground Balance: Automatic and manually adjustable for improved performance. Includes 175 points of Ground Balance resolution, allowing the AT Max to handle both conductive soils (such as saltwater beaches) and highly mineralized ground.
  • Automatic Ground Balance Window™: Garrett Exclusive feature will simultaneously ground balance to a range of values to help overcome localized ground variations. By reducing subtle ground responses, the Automatic Ground Balance Window smooths detector audio and allows the user to hear faint targets.
  • Larger Display Numbers: Digital Target ID number, Iron Discrim number, etc.
  • More Controls: All easily accessible with a single finger as you search.
  • Iron Audio™: Hear discriminated iron (normally silenced) to avoid digging tricky, undesired flat iron items.
  • All Metal Iron Audio™: Garrett Exclusive feature that audibly identifies discriminated iron while operating in a True All-Metal Mode.
  • Adjustable Frequency: Small frequency shifts to eliminate interference.
  • All Terrain Versatility: Fully submersible to 10-foot (3 meter) depth. Weatherproof design also protects against dusty and humid environments. For underwater use, optional wired headphones must be used.
  • Digital Target ID: 0 to 99 scale.
  • High-Res Iron Discrimination™: 44 points of iron resolution.
  • Adjustable Threshold: User can manually adjust the audio threshold (the constant background sound or “hum”) to better hear faint targets.
  • Pulse Width Modulation Audio: Proportional PWM audio response and Tone Roll Audio provide more target information and sharp, responsive target signals.
