The D60 is an integrated dual-frequency echosounder designed for USVs. The 200 kHz channel gives precise depths, while 33 kHz penetrates soft sediment to the harder layer below.

Built-in attitude and temperature sensors compensate in real time, and adaptive algorithms tune gain and range automatically – no manual settings.

CHCNAV D60 – 200 kHz + 33 kHz echosounder that finds the true bottom

The D60 is an integrated dual-frequency echosounder designed for USVs. The 200 kHz channel gives precise depths, while 33 kHz penetrates soft sediment to the harder layer below.

Built-in attitude and temperature sensors compensate in real time, and adaptive algorithms tune gain and range automatically – no manual settings.

Soft bottoms and sediment thickness

Measure the water depth and the mud

Comparing 200 kHz and 33 kHz returns shows sediment thickness for dredging, ponds and reservoirs. The D60 fits the Apache 4 and Apache 4 Pro directly (and the Apache 6 with a bracket), and a manned-boat kit is available. See how single-beam, multibeam and ADCP surveys work in our 3D animations.

How it works · 3D

Two frequencies, one survey: how the D60 finds the true bottom

The D60 sends 200 kHz and 33 kHz pings at the same time. The narrow 200 kHz beam gives centimetre-level depth to the first strong surface – the top of soft mud. The wide, low-frequency 33 kHz pulse loses less energy in mud, weeds and turbid water, so it reaches the harder layer below. Comparing the two gives sediment thickness on every ping.

Auto-tuning gain

200 kHz – precision

Narrow 6° beam, 0.2–250 m, ±1 cm + 0.1% of depth. Maps the water–sediment surface in detail – the surface you navigate over and dredge to.

33 kHz – penetration

Wide 18° beam, 0.8–1000 m. Lower frequencies lose less energy in soft mud, weeds and particle-laden water, so the echo comes from the firmer layer underneath.

Where the D60 shines

Dredging, settling ponds, lagoons and reservoir sedimentation
Weedy lakes and canals where single-frequency sounders read the weed tops
Turbid or rough water – auto-tuning in 0.2 s and a 100 Hz IMU
Mounts on the Apache 4 and Apache 4 Pro

Illustration with vertical scale exaggerated. How deep 33 kHz penetrates depends on sediment type, density, gas content and water mineralization – confirm thickness with a probe or core at a few points.

Real-time correction from water temperature.

Ultra-compact design

Half the size of a typical dual-frequency system

The integrated design shrinks the main unit to 16.2 × 12.1 × 6.4 cm and installs quickly on CHCNAV Apache USVs – one operator, one boat, one remote.

Calibration-free IMU

Every ping attitude-corrected

A high-precision IMU (roll and pitch ±0.1°, 20 ms latency) paired with the transducer compensates every depth at 100 Hz – stable even with instantaneous roll or pitch beyond 30°.

Intelligent auto-tuning

Reliable depths without expert settings

Adaptive algorithms read echo strength and depth in real time and correct gain and range within 0.2 s – ideal for turbid water and rapid depth changes.

Streamlined operation

One app from field to results

EasySail on the Android controller handles acquisition, real-time display, post-processing and export – no laptop required.

Questions

D60 FAQ

What is the D60 used for?

Bathymetry in turbid or variable-depth water and sediment-thickness surveys – 200 kHz finds the water–sediment surface and 33 kHz the harder bottom beneath.

Which USVs fit the D60?

The Apache 4 and Apache 4 Pro directly; the Apache 6 with a custom bracket. A manned-boat kit is also available.

Single-beam or multibeam?

The D60 is a single-beam, dual-frequency sounder. For swath mapping see the HQ-400 or HN-400M.
