EdgeTech 3400 Portable Sub-bottom Profiler

High-Resolution Wideband CHIRP Imaging for Strategic Sub-bottom Stratigraphy

Product Overview 

The EdgeTech 3400 is a high-performance, wideband Frequency Modulated (FM) sub-bottom profiler designed for high-resolution imaging of sub-bottom stratigraphy in oceans, lakes, and rivers. Built on EdgeTech's legendary Full Spectrum® CHIRP technology, the 3400 delivers superior penetration in various bottom types while maintaining the crisp vertical resolution required for precise geological and engineering assessments.

As a "Portable" system, the 3400 is engineered for flexibility, featuring a hydrodynamic towfish that can be easily converted for pole-mount operations. It is the industry’s premier choice for surveyors who need a versatile system that can transition from deep-towed offshore missions to shallow-water coastal surveys on small boats of opportunity.

Why Choose the EdgeTech 3400 Portable?

• Dual 2-16 kHz Transducers: Equipped with dual transducers, the 3400 provides a balance of deep penetration (up to 80m in clay) and high resolution (6–10 cm), making it a "do-it-all" tool for most sub-bottom applications.
• Unique "Pipeliner" Mode: The towfish features segmented PVDF receiver arrays that can be switched to a specialized mode optimized for the detection, location, and imaging of buried pipelines and cables.
• Real-Time Reflection Coefficient Measurements: Utilizing linear system architecture, the 3400 allows users to collect complex "analytic" data to measure sediment reflection in real-time, assisting in accurate sediment type determination.
• Integrated Motion & Position Sensors: The system includes internal sensors for pitch, roll, heave, and depth, ensuring all acoustic data is automatically corrected for vessel motion—a critical feature for high-accuracy surveying in rougher seas.
• Discrete Transmit/Receive Channels: Unlike many entry-level systems, the 3400 features separate channels that allow for continuous data collection and a high ping rate, essential for high-speed construction and pipeline surveys.
