Product Info

The EchoLogger ECT-series offers a scalable solution for shallow-water hydrographic surveys, environmental monitoring, and bathymetry in challenging bottom conditions. All models feature a compact and lightweight construction, making them ideal for USVs, ROVs, and UAV-integrated sonar payloads. Choose from single-frequency high-resolution or dual-frequency penetration-capable models to match your operational environment—from clean, ultra-shallow ponds to sediment-heavy reservoirs and weed-covered lakes. With real-time depth output, integrated tilt & temperature sensors (D24S/D052S), and compatibility with leading survey navigation software, EchoLogger sounders deliver dependable bathymetric data whether you're profiling soft sediments, measuring true bottom depth, or navigating through variable aquatic vegetation.

Key Features

1. Compact & Lightweight – Purpose-built for USVs, ROVs, and small platforms where payload efficiency matters.

2. Single & Dual-Frequency Options – Choose high-resolution or vegetation/sediment penetration depending on survey requirements.

3. Reliable Bottom Detection – Dual-frequency units differentiate vegetation, soft organic layers, and hard bottom.

4. Field-Proven Durability – Designed for real-world survey environments, including turbid, weedy, and sediment-heavy waters.

Delivery

Free UK Delivery is available on all orders over £100. 

Orders under £100 have a fixed delivery price of £8.
