Product Description

The F75 is the standard model without Boost and Cache modes and features a gold upper stem.
The F75LTD-BLK includes Boost and Cache modes, comes with both 11" and 5" searchcoils, and has a black upper stem.

The F75 series delivers top-tier performance for treasure hunters, relic enthusiasts, and professionals alike, offering two exceptional options tailored to varying needs. The F75 is the standard model, built for reliability and versatility, making it ideal for coin shooting, relic hunting, and even gold prospecting. With its powerful 13 kHz operating frequency, intuitive controls, and FastGrab™ ground balancing, this detector provides excellent depth and accuracy. It features a sleek gold upper stem and a waterproof 11" BiAxial™ searchcoil, ensuring it can tackle various environments, from parks to beaches.

For those seeking even more advanced detection capabilities, the F75LTD-BLK offers all the features of the F75, with the addition of Boost Process and Cache Locating Mode. These exclusive modes enhance depth penetration, making it possible to detect deeper, larger targets while maintaining accuracy in challenging terrains. Whether you’re working in highly mineralized ground or looking to uncover deeply buried relics, the F75LTD-BLK’s advanced technology excels where other detectors might struggle. It includes both an 11" and 5" searchcoil for added flexibility and comes equipped with a durable black upper stem, perfect for long detecting sessions in tough environments.

Both models are engineered for high performance, offering exceptional target separation, comprehensive EMI suppression via Digital Shielding Technology (DST), and a large, easy-to-read LCD screen that provides vital information on target ID, depth, and confidence levels. The F75 series is designed to deliver maximum depth and sensitivity without sacrificing usability, making it the go-to choice for serious metal detecting enthusiasts.

Purpose: General Purpose, Coin Shooting, Relic Hunting, Jewelry, Gold Prospecting

Frequently Asked Questions

What’s the best sensitivity setting for detecting in highly mineralized soil?

In highly mineralized soil, it’s recommended to reduce the sensitivity to around 60–70 and use manual ground balancing to minimize false signals.

How does the Boost Process affect detection depth in mineralized soil?

The Boost Process enhances depth even in mineralized soil, but it’s important to use a slower sweep speed to maximize accuracy in challenging ground conditions.

Is there a way to reduce iron audio without eliminating iron targets completely?

Yes, you can use the 2H or 2L tone modes, which will still detect iron but at a reduced audio volume, helping you avoid digging unnecessary iron targets.

What’s the ideal ground balancing method for saltwater beaches?

Manual ground balancing is preferred for saltwater environments, as the detector’s automatic FASTGRAB™ may not balance effectively on highly conductive soils like wet sand.
What’s the impact of using the smaller 5" coil on the F75LTD-BLK in trashy areas?
The smaller coil improves target separation in trashy areas, allowing you to better differentiate between valuable targets and metallic trash, while maintaining good depth in confined spaces.
What’s the recommended frequency for detecting gold nuggets with the F75?
For detecting small gold nuggets, use a higher frequency setting (around F1 or F2) and switch to JE mode, which enhances sensitivity to low-conductivity metals like gold.

Depth Detection Factors

The detection depth of a metal detector is primarily influenced by the size of the search coil. Typically, a coil will detect coin-sized objects at a depth roughly equivalent to the coil's diameter. For example, a 4" coil is likely to detect coin-sized objects up to 4" deep, whereas an 8" coil may detect similar objects at a depth of up to 8". However, detection depth can be significantly affected by several variables, including electromagnetic interference (EMI), detector sensitivity settings, and soil mineralization. 

Soil conditions play a crucial role in depth detection. Here are three common soil types that can impact performance: 

Highly Mineralized Soil: Rich in iron and other conductive minerals, this type of soil can cause false signals and reduce the detector's depth capability. The detector may struggle to differentiate between the soil and metal objects, leading to decreased accuracy. 

Wet or Saline Soil: Soils with high moisture content or salinity, such as those found near coastal areas, can enhance conductivity, causing the detector to register numerous false signals. This interference may mask deeper targets and limit the effective detection depth. 

Compact Clay Soil: Dense and compacted clay can create a challenging environment for metal detection. Its dense nature can impede electromagnetic signals, reducing the detector's sensitivity to deeper targets. Additionally, the moisture-retaining properties of clay may cause additional signal distortion. 

Understanding these factors and adjusting the detector's settings accordingly can help optimize detection depth and accuracy across various conditions.
