GeoScope 6100 Deep‑water Parametric SBP

100 kHz parametric SBP · rated 6,000 m

Rated to 6,000 m — Pressure housings built and validated with high redundancy for reliable operation at full working depth.
Up to 30 m penetration — Mature parametric technology resolves complex deep-sea sediment structure.
Narrow beam, no side lobes — A ~5.5° × 5.5° primary beam suppresses clutter and delivers ≤5 cm range resolution.
Split layout, easier integration — A 5 kg transducer and 15 kg electronics bottle mount separately, easing space and trim on deep-diving vehicles.

GeoScope 6100 is a parametric sub-bottom profiler rated to 6,000 m for deep-sea vehicles. Built on nonlinear acoustics, it transmits at a 100 kHz primary frequency and generates 5 – 20 kHz secondary frequencies with strong sediment penetration.

Transducer and electronics bottle are separate pressure-rated units, designed for integration on crewed submersibles (HOV), work-class ROVs and long-endurance AUVs. It holds range resolution at ≤5 cm while penetrating up to 30 m into the seabed — a profiler for deep-ocean science and deep-sea geological mapping.
