Endura Logger with 3 Sensor Ports
Designed specifically for USVs, the Endura-3 is the first infinite endurance profiler on the market. With no fragile mechanical connectors or finite battery life, the Endura Loggers were made to “set and forget”, unlocking the potential to do unlimited casts for hydrographic surveys. The Endura-3 has three sensor ports on the endcap; the sensor payload is modular and can be field-swapped to meet project requirements.

Endura Logger with 6 Sensor Ports
Designed specifically for USVs, the Endura-6 is the first infinite endurance multiparameter sonde on the market. With no fragile mechanical connectors or finite battery life, the Endura Loggers were made to “set and forget”, unlocking the potential to do unlimited casts for every parameter of interest. The Endura-6 has six sensor ports on the endcap; the sensor payload is modular and can be field-swapped to meet project requirements.
| Sensor port capacity | 6 |

Frequently Asked Questions
The Endura Loggers are the first connector-free, wirelessly charging instruments designed specifically for USV (Uncrewed Surface Vehicle) deployments. Unlike traditional systems, they eliminate fragile mechanical connectors and finite battery limitations, enabling reliable, long-term use in harsh marine environments.
The Endura-3 is an infinite endurance profiler with 3 modular sensor ports, ideal for hydrographic surveys. The Endura-6 is an infinite endurance multiparameter sonde with 6 modular sensor ports, optimized for collecting diverse environmental parameters. Both are built for 'set and forget' deployments with unlimited cast potential.
The Endura Loggers are engineered for high-performance in unpredictable, remote marine environments - making them ideal for long-duration USV missions. Extensive in-house bench testing, combined with 10 000 hours of deployments on various remote platforms has demonstrated their reliability under the most demanding conditions.
Yes. Both Endura-3 and Endura-6 feature modular, field-swappable sensor ports, allowing you to tailor your instrument to specific project needs without the need for specialized tools or returning to base.
