Smart Tether, a complete underwater navigation system, offers you unmatched operation with your VideoRay system or tethered diver. The Smart Tether system, which includes tether, control box, ultra-mobile PC and software, is designed to meet multiple missions and tested to survive extreme environments. No matter what your mission, the Smart Tether system makes it smarter, faster, safer, and easier.


Smart Tether includes a series of sensors nodes embedded in the tether itself. These nodes use acceleration, magnetic, and rate-gyro sensors to measure the orientation and track the position of your vehicle and tether. This data is then transmitted to the control box and displayed on your computer screen in real time. With Smart Tether, there is no need for additional external transponders or complicated set-up, measurement, and training. Since the sensors are embedded in the tether, you won’t need extra wires and batteries, either. It’s a “drop and go” system.


The Smart Tether system’s fast refresh rate gives your crew instant and accurate information about your diver's or VideoRay submersible's position. This real-time navigation facilitates missions that require precise operation, including: close-up inspections, rescue and recovery work, ordnance location, and homeland security operations.


Tides, currents, and wave dynamics can make precise underwater navigation using a fixed launch point nearly impossible. Smart Tether includes GPS integration to help you navigate your ROV or diver from a moving point such as a boat or barge.


Smart Tether makes navigation in the field simple, smart, and safe. The system displays the live position of your ROV or diver and tether, allowing real-time navigation, communication, and tether awareness. Smart Tether even provides a position history of visual and SONAR scans so your operators know what areas have already been searched.

“After using the Smart Tether, it’s something that I’m really glad that we do have on our recent system purchases because it’s a tremendous timesaver and a great piece of equipment.”Tom Wrasse, Conservation Warden Supervisor for the Wisconsin Department of Natural Resources
