Frequently Asked Questions
What is the operating frequency of the Fisher F19?
The Fisher F19 operates at a frequency of 19 kHz, making it highly sensitive to small and low-conductivity targets such as gold nuggets and small relics.
Does the Fisher F19 have manual ground balancing?
Yes, the Fisher F19 has manual ground balancing, allowing users to fine-tune the detector's settings for optimal performance in varying soil mineralization conditions.
Does the Fisher F19 have a backlight feature?
Yes, the Fisher F19 features an adjustable backlight for the display, which enhances visibility during low-light conditions or night-time detecting.
What is FeTone™ on the Fisher F19?
FeTone™ is an adjustable iron audio feature that allows users to adjust the volume of iron signals separately from non-ferrous signals, making it easier to distinguish between unwanted iron targets and desirable non-ferrous targets.
What is the purpose of the V-Break® feature on the Fisher F19?
The V-Break® feature allows users to set a variable tone breakpoint, customizing the tone response for different target ID ranges, enhancing target identification and discrimination capabilities.
What is the purpose of the Notch Width adjustment on the Fisher F19?
The Notch Width adjustment allows users to selectively filter out specific types of unwanted targets, such as pull-tabs or small iron objects, without affecting the detection of other valuable targets.

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.
