Frequently Asked Questions
Can I use the Fisher F11 in saltwater environments?
The Fisher F11 is not designed for use on wet sand saltwater beaches due to the high conductivity of saltwater. It is best suited for dry sand and other land environments.
What are the different operating modes of the Fisher F11?
The Fisher F11 features three operating modes: Jewelry, Coin, and Artifact. Each mode is optimized to detect specific types of metal objects, enhancing search precision.
What does the Notch feature do on the Fisher F11?
The Notch feature allows you to accept or reject specific target categories. By notching out unwanted metals, you can focus on detecting more valuable items.
What kind of audio feedback does the Fisher F11 provide?
The Fisher F11 provides four distinct audio tones (bass, low, medium, high) to help differentiate between different types of metals.
What does the 9-segment target ID mean?
The 9-segment target ID on the Fisher F11 provides a visual representation of the type of metal detected, ranging from iron (low conductivity) to silver (high conductivity), helping users quickly identify potential targets.
Can the Fisher F11 be used indoors?
While the Fisher F11 can be used indoors, it may be prone to interference from household electronic devices. It is best used outdoors where electromagnetic interference is less likely.

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.
