D270 Single-Beam Echosounder
CHCNAV D270 – portable 200 kHz single-beam echosounder
The D270 is a portable single-beam echosounder with a built-in water-temperature sensor that corrects sound velocity in real time for superior depth accuracy.
A cost-effective choice for river cross-sections, reservoir capacity and dredging volumes – with web-based setup, Wi-Fi and Bluetooth, and 8 GB of internal storage.
Controller, transducer and mast in one kit
The D270 runs on Linux with browser-based configuration from a PC, phone or Android app. Pair it wirelessly with a CHCNAV GNSS RTK receiver for accurate bathymetry; the OLED display shows voltage, depth and satellites at a glance, and shallow-water voice alerts improve safety. It is also the sounder built into every Apache USV. In Alberta, RTK corrections can come from the LATNET RTK network over 4G. See how single-beam, multibeam and ADCP surveys work in our 3D animations.
Why choose the D270
High-precision depth
Temperature sensor corrects sound velocity in real time.
Extensive range
0.15–200 m from rivers to reservoirs.
Portable
Light controller, quick setup.
Information at a glance
Voltage, depth and GNSS status on screen.
Wireless
Wi-Fi and Bluetooth to GNSS and phones.
Safety alerts
Voice prompts for shallow water and anomalies.
Real-time sound-velocity correction
The integrated water-temperature probe (–55 to +125 °C) corrects sound velocity as conditions change, giving ±0.01 m + 0.1% depth accuracy.
From 15 cm to 200 m
A 200 kHz transducer with a 6.5° beam and 300 W transmit power covers shallow rivers through deep reservoirs.
Light, wireless and easy to configure
The 0.84 kg controller, IP67 aluminium housing and wireless links make setup quick; configure from any browser and see key data on the 1.46″ OLED.
Compare CHCNAV echosounders
Single-beam sounders measure one depth under the boat; multibeam sounders map a full swath of the bottom on every pass.

D270 FAQ
What is the D270 used for?
River cross-sections, reservoir capacity, dredging volumes and general bathymetry from boats and USVs.
How deep can it measure?
From 0.15 m to 200 m.
How much data does it store?
8 GB internal.
Single-beam vs multibeam?
A single-beam measures one depth directly below the transducer; a multibeam such as the HQ-400 maps a full swath. See how single-beam, multibeam and ADCP surveys work in our 3D animations.
