Most metal detectors, including advanced Minelab metal detectors, cannot detect metals like stainless steel, pure lead, and certain non-magnetic alloys. These metals have very low magnetic permeability or electrical conductivity, making them difficult for standard detection technology to identify.
Metal detectors work by sending electromagnetic waves into the ground. When a metal with good conductivity (like gold, silver, or copper) is present, it disrupts these waves, creating a detectable signal. However, metals like stainless steel or lead do not react strongly to this signal, so they may remain undetected unless using specialized equipment.
For example:
- Stainless Steel – Highly resistant to corrosion, but has low conductivity, making it harder to detect.
- Lead – Heavy and dense, but with low reactivity to electromagnetic fields.
- Certain Alloys – Some nickel or aluminum blends are challenging to pick up without high-sensitivity settings.
If you’re searching for gold, a gold metal detector or a gold detector machine is the best choice. Minelab offers high-performance detectors that can even locate tiny gold nuggets, making them popular in metal detector shops near me.
Whether you’re checking the metal detector price in India or looking for a 10 feet deep metal detector price in India, knowing what metals your detector can and cannot detect will save you time and improve your search results.
In India, hobbyists and professionals often choose Minelab metal detectors for their reliability and advanced technology. From gold hunting to security checks, understanding your device’s limits will help you choose the right model and settings for your needs.
