Built for Ultimate Control

Wireless Synchronizations

Up to 24 Opals in one wireless network.

Record Natural Movement

Subject will wear it and forget it.

Real-Time Results

Continuously stream data for real-time processing.

Never Lose Data

Over 30 days of kinematic data can be stored on each Opal.

Long Battery Life

16 hours of battery life while logging data and more than 8 hours while streaming data.

Use Anywhere

Break out of the lab and record movement anywhere.

Assess Functional Mobility Anywhere

Easy to collect, analyze, and store data. Attach sensors to your subject, and instruct them to perform a standardized test. A report is then automatically generated to compare against normative values. This process takes less than five minutes.
