Description
Long-range, long-term, and reliable, the LONG RANGER is the best choice for gathering detailed data on seasonal and annual current structure fluctuations for scientific research and offshore oil and gas applications. Hundreds of Long Ranger units are currently deployed on: • environmental monitoring buoys • offshore oil rigs • polar research moorings The highly flexible Long Ranger unit is available in three product configurations: self-contained, direct reading, or remote- head— depending on your application requirements. Third-party solutions Collect data at your desk: the Long Ranger is designed to operate in real-time data mode. Third-party products are available for acoustic and radio data transfer direct to your location.
Product Features:
• Precision data: Broadband signal processing produces precise measurements, allowing for frequent sampling with extended battery life.
• Proven reliability: The Long Ranger inherits the Workhorse family of electronics, which have been proven in thousands of field applications.
• Extended deployment life: Set it and forget it. The Long Ranger can handle three, six or twelve month long deployments, from frigid polar waters to the balmy tropics.
