Overview
The VHL series Land 3C string is a three-component geophone assembly designed for multi-wave and multi-component seismic data acquisition. It features high sensitivity, low distortion, controlled damping, linear response, waterproof sealing and high resolution. The unit provides reliable surface coupling in silt, swamps and loose buried sand. Universal resonant frequency range: 8 Hz to 40 Hz. Suitable for single-unit use or combined arrays.

Series / Model
VHL series Land 3C string (VHL series)

Key features

• Compact, lightweight and streamlined design for easy deployment
• Alloy external housing for mechanical protection and impact resistance
• Sealed construction for long-term field waterproofing
• Integrated bubble level and orientation markings for correct sensor alignment
• Robust housing-to-internal coupling to improve surface coupling
• High shell strength enabling use on firmer surfaces
• Internal arrangement accepts multiple geophone models for single-point acquisition
• Dedicated six-core connector for centralized field connections
• Universal resonant frequency: 8 Hz to 40 Hz
• Designed to provide good coupling in silt, swamps, loose sand, tidal flats and snow

Applications
Land seismic exploration, single-point or combined seismic data acquisition in silt, swamp, snow, loose sand and tidal-flat environments.
