How is gold detected?
As the coil passes over the target the signal rises; the app looks at the decay character of the signal, i.e. the conductivity of the target, to determine the target type. The target card moves from “waiting for conductivity” to a result; when gold is classified, a “Gold detected” alert appears and the speaker tone rises with signal strength.

What is on the screen?
- Signal: live signal strength in dB and the threshold line
- Depth: estimated depth in metres
- Target: target type such as gold nugget or gold chest
- Coil: the coil in use (mono Ø33 cm or 2×2 m frame)
- Oscilloscope: the pulse decay curve
For all app screens, see the HS Detector mobile app.
Near the surface and deep down
In the demo video the Ø33 cm mono coil finds a gold nugget at 22 cm and the 2×2 m frame coil a gold chest at 5 metres. Real search depth depends on the target size, the mineral content of the ground and the coil; the app shows the estimated depth for the selected coil.
An app for your own gold detector
If you make or sell gold detectors, I can build a device-specific mobile app with target classification and a depth display: metal detector app development. For the technical foundation: pulse induction detector software.

Frequently asked questions
How does the gold detector app work?
It connects to the detector; when the signal rises it determines the target type by conductivity and shows a “Gold detected” alert when the target is classified as gold.
Does the app show depth?
Yes. It shows the estimated depth in metres for the selected coil.
How deep can each coil go?
The Ø33 cm mono coil is for small targets near the surface, the 2×2 m frame coil for large and deep targets; depth depends on target size and ground.
Can I have a gold detection app built for my detector?
Yes. I build an app with target classification and depth display based on your device's data output.
