Hi-Target iBeam 8140S Multibeam Echo Sounder

Overview

The Hi-Target iBeam 8140S is a compact multibeam echo sounder developed for high-resolution underwater terrain mapping and hydrographic surveys. With a depth measurement range of 0.2–200 m and a wide 150° swath coverage, the system enables surveyors to collect dense bathymetric data across rivers, reservoirs, navigation channels, and other inland or coastal waters.

Its lightweight transducer integrates acoustic measurement, motion sensing, and processing components into a compact design. Weighing approximately 1.7 kg, the iBeam 8140S is particularly suitable for installation on small survey vessels and unmanned surface vehicles (USVs).

Key Features

High-Density Multibeam Bathymetry

Unlike conventional single beam echo sounders, the iBeam 8140S collects depth measurements across a wide swath, supporting detailed underwater terrain mapping and more complete survey coverage.

Wide 150° Swath Coverage

A maximum swath angle of 150° allows the system to survey a broad section of the water bottom during each pass, helping improve coverage efficiency.

Compact and Lightweight Transducer

The approximately 1.7 kg transducer simplifies transportation, installation, and integration with compact survey platforms, including unmanned survey boats.

Integrated Inertial Navigation

The built-in inertial navigation system provides vessel motion information for compensating survey measurements during operation, helping maintain data quality in changing water conditions.

Narrow Beam Design

The 1.4° × 1.7° beam angle supports detailed representation of underwater terrain features, channel profiles, and submerged structures.

Flexible Survey Platform Integration

The compact system can be integrated into suitable manned survey vessels or USVs for bathymetric data acquisition in waterways where larger survey platforms may be impractical.

Hydrographic Data Collection and Processing

Compatible HiMAX multibeam surveying software supports survey line management, data acquisition, bathymetric visualization, and processing workflows.
