Knudsen Pinger Sub Bottom Profiler

A portable CHIRP sub-bottom profiler designed for shallow-water surveys, combining dual low-frequency channels (3.5 & 15 kHz) for sediment penetration with a 200 kHz channel for high-resolution seabed definition. The system delivers up to 2 kW output power, configurable pulse lengths, and supports industry-standard formats like SEGY and XTF. Compact and field-ready, it operates from a 24 VDC supply, mounts over the side, and can achieve up to ~40 m sub-bottom penetration in soft sediments.
