Reason For Slow Scanning During Metal Detection


When you’re using a metal detector, you might notice that scanning too quickly doesn’t give you the best results.

One big reason for this is that metal detectors need time to process what they’re sensing underground.

If you move too fast, the detector might miss small or deeply buried objects. It’s like when you walk quickly past a bookshelf and miss seeing a small book tucked in the corner.

Moving slowly allows the metal detector to accurately identify signals and alert you to buried treasures.

Another reason for scanning slowly is that metal detectors often need to filter out unwanted signals.

These could come from minerals in the ground, trash, or other metallic objects that aren’t what you’re looking for.

When you move slowly, the detector has more time to differentiate between valuable targets, like coins or jewelry, and junk.

This careful approach not only helps you find more interesting items but also saves you time and effort in the long run by reducing false alarms.

Importance of Slow Scanning

Let’s explore 8 key factors by GoldXtra that explain why slow scanning is sometimes needed to make sure no treasure is missed!

  • Detector Sensitivity
  • Soil Type and Mineralization
  • Target Size and Depth
  • Discrimination Settings
  • Coil Size and Type
  • Detector’s Operating Frequency
  • Environmental Conditions
  • User Experience and Skill Level
  • Recommendations for Effective Metal Detecting

1. Detector Sensitivity:

Sensitivity in metal detectors means how well they can sense metals buried underground. If the sensitivity is high, the detector can feel even small or deeply buried metals. 

But you’ll need to move it slowly to catch those signals properly. It’s like tuning your ears to hear very soft sounds.

2. Soil Type and Mineralization:

   It matters the kind of soil you’re searching in. Some soils have many minerals and can mess with your detector’s signals.

In such cases, moving the detector slowly helps tell apart false signals from real ones, ensuring you don’t miss out on hidden treasures.

3. Target Size and Depth:

   The size and how deep the metals are buried also count. Tiny objects or those that are way down in the ground need the detector to be moved slowly so that it can pick up their signals clearly and you can find them.

4. Discrimination Settings:

   Discrimination settings in metal detectors help the detector ignore useless metals and only alert for the good stuff. When this setting is high, moving slowly ensures it works effectively, so you’re not wasting time digging up trash.

5. Coil Size and Type:

   The coil is like the detector’s ‘ear’. Bigger coils can hear deep signals, but they need to be moved slowly to hear clearly, especially for small or deep treasures. It’s about giving the detector enough time to “listen” carefully.

6. Detector’s Operating Frequency:

   Frequency is like the pitch of the detector’s ‘voice’. Lower ‘voices’ are good for big, deep treasures, but you need to go slow to ensure that every ‘note’ is heard and no valuable item remains buried.

7. Environmental Conditions:

   Weather and surroundings affect the detector. Wet ground, high temperatures, or other electronic signals can make detection tricky. Going slow ensures that, despite these challenges, you don’t miss the treasures lying underneath.

8. User Experience and Skill Level:

   Your skill level affects how well you find treasures. If you’re new, taking it slow helps you understand the detector’s signals better, making sure you don’t overlook any hidden gems. 

Recommendations for Effective Metal Detecting:

Adjust the detector’s sensitivity according to where you’re searching, pick the right coil for what you want to find, and keep practicing to get better at understanding the signals. It’s like learning to listen and understand a new language, the more you practice, the better you get!


So, now you know the different factors by GoldXtra that make slow scanning important in metal detecting. It’s not just about waving the detector around quickly; taking your time can help you find more hidden treasures!

Remember, different soils, weather conditions, detector settings, and your experience level all play a role in how effective your treasure hunting can be.

We hope that next time these tips on metal detecting can help you the next time you’re out with your metal detector while considering these factors and taking it slow—you might just find something amazing!
