Small gold nuggets are faint targets in often heavily mineralized ground. High-frequency VLF detectors, often above about 40 kHz, are sensitive to small gold and are lighter and cheaper. Pulse induction and similar gold-focused technologies cope better with mineralization and reach larger, deeper nuggets. Learn to ground balance, expect hot rocks, and check for active mining claims before you detect.
Gold detecting rewards patience. The right detector and an understanding of the ground matter more than luck.
Technology
| High-frequency VLF | Pulse induction and gold-specific technologies | |
|---|---|---|
| Small gold | Very sensitive | Good on many models |
| Mineralized ground | Struggles in extreme ground | Handles well |
| Depth on larger nuggets | Moderate | Strong |
| Weight and price | Lighter, cheaper | Heavier, pricier |
Ground
Goldfields are often full of iron minerals that create noise. Ground balance carefully and expect hot rocks; learn their signals.
Coils
Small coils find tiny nuggets in rough terrain; larger coils cover ground for bigger targets. See search coils.
Claims and land
On US public lands, active mining claims give the claimant rights to the minerals. Check land status and claims with the BLM or Forest Service before you detect, and follow the laws and permission guide.

Common questions
What frequency is best for gold detecting?
High frequencies, often above about 40 kHz on VLF detectors, are most sensitive to small gold.
What are hot rocks?
Mineralized rocks that give signals like a target, common in goldfields.
Can I prospect anywhere on public land?
Not on active mining claims without permission. Check land status and claims with the land manager first.
Is pulse induction better for gold?
PI handles mineralized ground and larger, deeper nuggets well, while high-frequency VLFs are often better on tiny gold.
