  • What is the estimated shipping time ?
    We offer two shipping options: Standard and Express. For Standard Shipping, the estimated delivery time varies depending on the destination. Typically, it takes 8-30 business days to arrive. If you prefer a faster delivery, we also offer Express Shipping. With this option, you can expect your package to arrive within 3-7 business days. To ensure peace of mind and transparency, we include a tracking number with every order. This tracking number allows you to monitor the progress of your shipment and provides real-time updates on its whereabouts. Please note that these delivery times are estimates and can be subject to slight variations due to unforeseen circumstances or customs procedures. However, we strive to ensure timely delivery and will assist you in any way possible should any issues arise.
  • Can Fluxgate sensors find Gold?
    Our Fluxgate sensors are designed to detect ferromagnetic materials, which unfortunately means they cannot detect gold. However, it's worth noting that gold is often found in chests that are typically made from ferromagnetic materials.
  • What is the maximum depth at which fluxgate sensors are capable of detecting an object?
    The detection depth of fluxgate sensors varies depending on factors such as soil type, object size, and material composition. Under favorable conditions, these sensors can detect objects as large as a car at depths of up to 10 meters.
  • Which 3 axis magnetometer is best suited for drones?
    For drone applications, we would highly recommend considering the FG-43 magnetometer due to its lightweight and compact design. However, the FG-33+ magnetometer is also a viable option that can meet your requirements.
  • What measures can be taken to ensure stable performance of flux gate sensors in high-temperature environments?
    To maintain stable temperature conditions for flux gate sensors in high-temperature environments, one effective approach is to bury them in soil. This helps provide a more consistent and controlled temperature environment, ensuring their stable operation.
  • Can the flux gate sensors provide sufficient sensitivity to accurately measure variations in Earth's magnetic field caused by phenomena like coronal mass ejections and magnetic storms?"
    Yes, the FG-3+ sensor is indeed sensitive enough to measure variations in Earth's magnetic field caused by phenomena such as coronal mass ejections and magnetic storms.
  • Do you provide a tax-free option for businesses?
    Yes we do. We kindly request you to fill out this form, and rest assured, we will swiftly prepare your invoice for you.
  • What Payment options do you accept?
    For Payments we accept Bank Transfer, Paypal and Credit Cards.
