Unmanned surface vehicles have become a standard platform for hydrographic survey, and the echosounder is the part that turns a USV into a survey boat. Echologger builds compact, lightweight, low-power echosounders that integrate cleanly into USVs and autonomous survey craft, delivering survey-grade depth data without straining the vehicle's payload or power budget.

The ECT400 is the most popular choice for straightforward USV bathymetry, with the dual-frequency ECT D24 and ECT D032 adding backscatter alongside precise depth for bottom characterisation. Each can be hull-mounted for permanent USV installations or pole-mounted for quick deployment, and connects over USB or serial so depth data feeds directly into the vehicle's autopilot and data-logging system.

From a USV, these echosounders support full hydrographic surveys, shallow-water mapping and environmental monitoring — reaching areas that are unsafe or impractical for a crewed boat, lowering survey cost and keeping personnel out of hazardous water. Their compact size makes them equally suited to small electric USVs and larger autonomous survey platforms.

Survey companies, USV manufacturers, research institutions and government agencies use Echologger echosounders to equip unmanned surface vehicles for reliable, repeatable bathymetric survey across coastal, inland and nearshore waters.
