Unearthing Treasure: Mastering Metal Detector Discrimination Modes
Metal detecting can be an exciting and rewarding hobby for many enthusiasts. Whether you’re a beginner or a seasoned detectorist, it’s important to be aware of the various discrimination modes available on metal detectors. Discrimination modes allow users to filter out unwanted targets based on their conductivity or composition, helping to focus on valuable finds.
In this comprehensive guide, we will explore the top 8 discrimination modes commonly found on metal detectors and discuss how they can enhance your metal detecting experience.
1. All Metal Mode:
All Metal mode is a versatile setting that detects all types of metals without any discrimination. This mode is ideal for general metal detecting when you want to uncover all buried objects regardless of their composition. It’s particularly useful in areas where you might encounter a variety of targets and want to ensure you don’t miss anything valuable.
While All Metal mode provides maximum sensitivity, it also means you’ll dig up more trash items like bottle caps, nails, and other undesirable objects. However, using this mode can help you identify hotspots with high levels of activity before switching to more selective discrimination settings.
2. Discrimination Mode:
Discrimination mode is one of the most common features on modern metal detectors. This setting allows users to selectively ignore certain types of metals based on their conductivity levels. By adjusting the discrimination level, detectorists can choose which targets they want to detect and which ones they want to reject.
For example, if you’re looking for coins and jewelry while avoiding iron nails or pull tabs, you can set the discrimination level accordingly. Keep in mind that higher discrimination levels may cause you to overlook smaller or deeper targets made from valuable metals like gold or silver.
3. Notch Discrimination:
Notch discrimination takes traditional discrimination one step further by allowing users to create custom acceptance windows for specific target categories while rejecting others within the same conductivity range. This feature is beneficial when hunting in areas with mixed trash and treasure signals.
By setting notches at different points along the target scale, detectorists can fine-tune their detectors to only respond to desired items such as coins while ignoring unwanted objects like aluminum foil or steel bottle caps. Notch discrimination offers greater control over signal filtering compared to standard discrimination modes.
4. Tone Discrimination:
Tone discrimination assigns different audio tones or pitches to various target categories based on their conductivity levels. This feature adds an auditory dimension to metal detecting by providing distinct sound signals for different types of metals detected by the coil.
For example, high-pitched tones may indicate valuable targets like silver coins or jewelry, while low tones could signify ferrous materials such as iron nails or rusted tin cans. Tone discrimination helps detectorists make quick decisions about whether a target is worth digging based on its audio signature alone.
5. Iron Audio:
Iron Audio is a specialized form of tone discrimination designed specifically for identifying ferrous (iron-based) targets among non-ferrous items in the ground. When activated, this feature produces a unique audio response whenever the detector encounters iron objects below the coil’s surface.
By listening for distinct iron tones alongside regular target signals, detectorists can determine if there are potential artifacts hiding beneath layers of trashy iron debris without having to visually inspect each find individually. Iron Audio enhances detection accuracy in areas where iron contamination poses challenges during treasure hunting expeditions.
