Whites TDI: A Pulse Induction Detector for All Terrains

Whites TDI: A Treasure Hunter’s Dream Machine – Unlocking the Power of Pulse Induction Technology

Whites TDI was released in 2008 and is still in production as the TDI SL. It is based on the Goldscan technology developed by Eric Foster, a pioneer in PI detectors. The TDI stands for Target Discrimination Identification, which refers to the detector’s ability to distinguish between different types of targets based on their conductivity. The TDI has a 3-way target conductivity selector that allows you to hear either only low-conductive targets like most gold nuggets, or high-conductive targets like silver coins and large relics, or both. This feature is useful for avoiding unwanted targets and focusing on your desired ones.

Pulse induction (PI) metal detectors are known for their ability to detect deep and small targets in highly mineralized soils and saltwater environments. They are also immune to electromagnetic interference, which can affect other types of detectors. However, PI detectors also have some drawbacks, such as poor discrimination, high weight, and high cost. White’s Electronics, a leading manufacturer of metal detectors, has developed a PI detector that aims to overcome these challenges and offer a high-performance and versatile machine for all terrains.

What is Pulse Induction (PI) Technology?

PI technology is a type of metal detector technology that uses pulses of electromagnetic energy to detect metal objects. PI detectors are known for their depth penetration, which makes them ideal for finding deep targets.

Whites TDI also has a full-control ground balance that can balance out the iron mineralization of hot rocks, black sand, and other tough ground. This feature improves the detector’s depth and stability, and allows you to hunt in areas that might be difficult for other detectors. The TDI has a ground balance switch that lets you turn the ground balance on or off, depending on the conditions. When the ground balance is on, the detector produces a dual-tone audio response that varies depending on the target’s conductivity and position relative to the ground balance point. When the ground balance is off, the detector produces a single-tone audio response that is more sensitive to all targets.

Whites TDI also has an adjustable pulse delay that lets you fine-tune the sensitivity and depth of the detector. The pulse delay is the time between the transmit and receive pulses of the detector, and it affects the size and depth of the targets that the detector can detect. The TDI has a pulse delay range from 10 ms to 25 ms, with lower values being more sensitive to smaller and shallower targets, and higher values being more sensitive to larger and deeper targets. You can adjust the pulse delay to suit your preferences and the type of targets you are looking for.

Whites TDI comes with a 12-inch spider coil that is waterproof and covers a lot of ground. You can also use other accessory coils from White’s to suit your needs. The TDI has a frequency control that helps you avoid interference from power lines and other sources, and a battery life indicator that shows you how much juice you have left. The TDI runs on two rechargeable lithium-ion batteries that last for several hours.

What are the benefits of using the Whites TDI?

There are many benefits to using the Whites TDI. Here are just a few:

  • Superior depth penetration
  • Excellent performance in mineralized ground
  • Precise target identification
  • Ability to ignore unwanted targets
  • Precise target location
  • Lightweight and ergonomic design
  • Waterproof construction
  • Long battery life

Whites TDI is easy to use and has a simple control panel with only four knobs and a switch. You can adjust the threshold, ground balance, pulse delay, and conductivity, and choose between ground balance on or off. The TDI produces a dual-tone audio response that varies depending on the target’s conductivity and position relative to the ground balance point. You can hear a high-low tone for low-conductive targets like gold nuggets, a low-high tone for high-conductive targets like silver coins, or both tones for all targets.

Whites TDI is a powerful and sensitive detector that can find small and deep targets that other detectors might miss. It can also discriminate between different types of targets based on their conductivity, which is useful for avoiding trash and iron. However, the TDI does not have a visual display or a pinpoint mode, so you have to rely on your ears and your digging skills to locate and identify your targets. The TDI is also a bit heavy and bulky, so you might need a harness or a hip mount to reduce fatigue.

Whites TDI is a great detector for anyone who wants a PI machine that can handle various terrains and targets. It is especially suited for gold prospecting, relic hunting, and beach detecting, where its depth and sensitivity give it an edge over other detectors. The TDI is also a durable and well-built detector that can last for years. If you are looking for a PI detector that offers high performance and versatility, the White’s TDI might be the one for you.
