6Fg8 has released a pretty cool app that detects metal using the HTC HD2. The application (artwork by youmeus) is still in beta but is functional with ongoing bug fixing and development.
Metal Detector currently only works on the HD2, as it uses the built-in compass and calculates the deviation from magnetic north. This only works on the HD2 as it houses a real physical magnetic compass and the sensor API on other devices will likely differ. It requires .NETCF3.5 to run, and can be installed on either device memory or storage card.
6Fg8 has stated that the app will remain freeware.

All gauges are fully functional. Clicking sound and vibration working too. You may turn them on/off using the corresponding buttons on the left. To exit the app, use the lower right button. The camera button has a new meaning as of v0.2.0.0: It enables a test mode, where sensor readings are simulated. Use the sliders to advance the main/aux gauges.
Calibration and testing:
Place your device flat on a surface. After starting the app, the gauge should show zero. If it doesn’t, take your device and write a couple of “eights” in the air (this is to get rid of magnetism which might get stuck in the sensors). Then use a pair of scissor or something the like and move it slowly to the right side of your device. At a distance of approx. 5 cm. the gauge should start to move. Take your device and move it with its right side near metals, and see if the gauge shows values.
Planned future developments:
- DONE new skin
- DONE sound ticks
- DONE- vibration
- adjustable sensitivity and offset
- improved detection algorithm
- 3rd party skinning options
- save vibrate and sound settings
