    Q: I lost my physical copy of the Orbitor Prospector 100 Metal Detector Manual. Can I get a PDF? A: While Orbitor has discontinued this specific model, you can often find scanned PDFs on enthusiast forums like TreasureNet or DetectorProspector.com. Alternatively, use this guide as your primary reference.

The manual recommends a higher frequency detector (18 kHz+) for dedicated gold prospecting. The original Orbitor Prospector 100 manual suggests this
