Golden Mask Altus, WS107, 11x14 inch search coil

The Golden Mask Altus is a real game changer. It incorporates the new Golden Mask Binary Sinus Pulse (BSP) hybrid technology to outperform any detector on today's market. The shape and cycle of emitted magnetic fields are key to achieving superior detection depth. Mass-market detectors typically use one of two field types:

1. Continuous Sinusoidal Fields (VLF-based):

Efficient, lightweight, fast-response, and easy to produce with good discrimination.

Drawbacks: Shallow depth, poor ground noise suppression, and reduced performance in mineralized soils.

2. Pulsed Rectangular/Trapezoidal Fields (PI-based):

Greater depth, robust in diverse soils, and broader signal range.

Drawbacks: High power consumption, heavy, very expensive, complex, and slow signal analysis with poor selectivity.

To overcome these limitations, GM developed BSP (Binary Sinus Pulse) — a hybrid waveform combining two sine signals of different frequencies, producing a continuous bipolar pulse with sinusoidal edges and plateaus.

BSP technology key benefits:

• Exceptional depth performance

• Full ground and cavity noise suppression

• Wide signal spectrum detection

• Strong magnetic field with low power use (high efficiency)

• Lightweight and compact

• Simple antenna system

• High immunity to external interference

• Superior discrimination and selectivity

• Fast, clear target response (high scan rate)

BSP merges the strengths of both VLF and PI systems without their flaws. It supports both deep relic hunting and fast coin shooting. BSP is already implemented in the fast and deep-seeking ALTUS detector.

This detector "loves" targets with high VDI - 60 and above. It could detect such targets at incredible depths, while low-VDI targets are detected at "normal" depth, comparable to the best detectors on today's market.
