    Frequently Asked Questions

    What is pulse induction (PI) technology, and how does it differ from VLF detectors?

    Pulse induction (PI) uses short bursts of energy to detect metal objects, making it less sensitive to mineralized soil and saltwater compared to VLF (Very Low Frequency) detectors, which rely on continuous frequency signals. PI is ideal for detecting targets in highly conductive environments like wet sand and saltwater.

    How does the adjustable pulse delay benefit treasure hunters?

    The adjustable pulse delay (7µs to 11.5µs) allows users to fine-tune the detector’s sensitivity to specific targets. A lower pulse delay increases sensitivity to small gold objects, while a higher delay minimizes interference from conductive saltwater or black sand.

    What is the significance of the Fisher Impulse AQ's Zero Target Separation (ZTS®) feature?

    Zero Target Separation (ZTS®) ensures the detector can identify closely spaced objects without missing valuable targets. This is especially useful in areas with mixed metal content, like beaches littered with trash and treasure.

    What is the purpose of the Volcanic Sand Mode on the Impulse AQ?

    Volcanic Sand Mode is designed for use on extreme black sand beaches, where mineralization is high. It adjusts the detector’s sensitivity to reduce interference, allowing it to still perform well in highly mineralized areas where most detectors fail.

    How does the Highly Reactive System (HRS®) benefit beach hunters?
    The HRS® technology allows the Impulse AQ to maintain a fast recovery speed while detecting, ensuring that even when moving quickly over large areas, small and valuable targets are not missed.
    What are the advantages of the Fisher Impulse AQ’s multitone audio system?
    The multitone audio system provides distinct audio signals for different types of metal, allowing users to quickly identify whether a target is likely to be valuable (like gold or silver) or trash (like iron or aluminum).
    Can the Fisher Impulse AQ be used for underwater detecting?
    Yes, the Impulse AQ is waterproof up to 3 feet (1 meter), making it suitable for shallow water detecting, wading, and detecting in the surf zone.
    Why does the Impulse AQ use multiple pulse frequencies depending on the detection mode?
    The Impulse AQ utilizes different pulse frequencies across its detection modes to optimize for various environments. Higher frequencies (4.02-4.17kHz) in All Metal mode enhance sensitivity and depth, while lower frequencies in Volcanic Sand mode (1.54-1.56kHz) help manage extreme mineralization by reducing noise and ground interference.

    Depth Detection Factors

    The detection depth of a pulse induction (PI) metal detector is influenced primarily by the search coil size, but unlike VLF detectors, PI technology excels in challenging environments like wet sand and mineralized soils. In general, a coil can detect coin-sized objects at a depth roughly equivalent to its diameter. For instance, a 4" coil may detect objects up to 4" deep, while an 8" coil may reach depths of 8". However, depth can be affected by factors such as electromagnetic interference (EMI), detector sensitivity, and ground conditions.

    Pulse induction detectors are particularly effective at maintaining depth in challenging soil conditions:

    Highly Mineralized Soil: PI detectors are less impacted by conductive minerals like iron, which commonly cause false signals in VLF detectors. The PI system transmits short bursts of energy, allowing it to differentiate between mineralized ground and metal targets, providing more accurate detection depth in these conditions.

    Wet or Saline Soil: PI detectors excel in wet, salty environments such as beaches, where VLF detectors typically struggle. The ability of PI detectors to ignore the conductivity of wet or saline soil allows for greater detection depth and fewer false signals, making them ideal for beach hunting.

    Compact Clay Soil: Although compact clay can still reduce detection depth due to its density, pulse induction technology’s ability to penetrate dense soil with powerful, short pulses makes it more effective than VLF detectors in detecting deeper targets in this type of soil.

    Adjusting pulse delay and sensitivity settings on a pulse induction detector helps optimize performance across various ground conditions, maximizing detection depth and accuracy.
