How It Performs On Each Terrain

🏖 Beach Detecting

Capable on dry beach but single-frequency VLF means wet salt sand causes instability. Use with manual ground balance carefully.

🪙 Gold Prospecting

Its 13 kHz frequency gives reasonable sensitivity to small gold in moderate soils. Not a dedicated gold machine but holds its own.

🌱 For Beginners

Too complex for true beginners. The 99-level sensitivity and advanced ground balance need experience to use effectively.

🪙 Coin Shooting

One of the best single-frequency coin shooters. Its depth, combined with the 5-tone audio, makes it outstanding for deep coin hunting.

🏹 Relic Hunting

Excellent relic detector. Deep, sensitive, and the DD coil handles heavy mineralisation in farmland and battlefields well.
