Hi-Target HD-MAX II Dual-Frequency Echo Sounder

Overview

The Hi-Target HD-MAX II is a professional dual-frequency echo sounder designed for hydrographic surveying in shallow and deep water environments. Featuring high- and low-frequency sonar channels, it supports bathymetric data collection in rivers, reservoirs, navigation channels, and areas with challenging bottom conditions.

The HD-MAX II is particularly suited to dredging surveys, sediment investigations, and projects involving high-turbidity water. Its integrated survey computer, 15-inch display, and SLHydro Sounder software provide a complete platform for depth measurement, survey navigation, and hydrographic data processing.

Key Features

Dual-Frequency Depth Measurement

The high-frequency channel supports detailed depth measurements, while the low-frequency channel provides extended sounding capability for deeper water and sediment-related survey applications.

Wide Depth Measurement Range

The system supports depth measurements from 0.15 to 300 m at 200 kHz and from 1 to 2,000 m at 24 kHz, allowing surveyors to work across different water depths with suitable transducer configurations.

Adaptive Depth Processing

An automatic depth detection algorithm helps improve sounding performance in varying underwater terrain and challenging survey conditions.

Integrated Sound Velocity Support

The transducer incorporates a temperature sensor to support sound velocity calibration, helping surveyors account for changes in water conditions.

Integrated Survey Computer and Display

A 15-inch display, onboard computer, and high-capacity storage allow operators to manage sounding data and survey workflows directly from the instrument.

SLHydro Sounder Software

The software supports survey planning, navigation, data acquisition, external sensor integration, processing, and export of hydrographic survey data.

Rugged Housing and Flexible Connectivity

The IP66-rated magnesium alloy housing is designed for demanding field environments. Multiple communication interfaces support integration with positioning systems and other survey equipment.
