【Ultra-Precise Velocity Tracking】Our linear encoder auto-calculates your barbell speed (m/s), power output (W), 1RM and fatigue index during lifts like squats and cleans, allowing you to optimize your training and prevent overtraining through scientific testing. While customizable voice announcements keep you focused without checking your phone. 【Pro-Grade Sensor】This weightlifting power measurement device uses an industrial servo position sensor (rated load 15-20kg) to provide lab-grade data in the gym. The 70x70x35mm casing survives drops from racks and repeated impacts, delivering consistent <1% error margin even during max-effort snatches or plyometric jumps. 【50H Ultra-Long Battery】Our smart speed tracker has 10 times longer battery life than ordinary gym trackers - just 2H of charging can meet a week's training needs. niversal Type-C interface works with any mobile phone charger/power bank, never miss any action due to dead battery again. 【Real-time App Tracking】VBT encoder uses advanced APP program control technology, which allows you to view training data in real time on the mobile phone APP. It supports viewing speed, distance, power, number of times, fatigue detection and other sports data. Voice coaching calls out PRs and form tips, while screen projection lets coaches view data on TVs/tablets during team sessions. 【Complete VBT Device for All Athletes】The Velocity based training tool Includes a 5m wire rope(self-retracting, non-tangle) handles squats, sled drags, and plyometrics.
