• 【COMPLETE VBT EQUIPMENT FOR ALL ATHLETES】This speed-based training tool includes a 5.0m long wire rope (automatic retractable, anti-entanglement) for squats, sled drags and plyometrics. The magnetic bracket can be installed on the training rack/barbell plate in 2 seconds without worrying about loose straps or clips. Trusted by weightlifters and strength coaches around the world.
• 【ULTRA-ACCURATE SPEED TRACKING】Our linear encoder automatically calculates your barbell speed (m/s), power output (W), 1RM and fatigue index in squats, etc., through scientific testing, to help you optimize training effects and prevent overtraining. Customizable voice broadcast allows you to stay focused without checking your phone.
• 【PROFESSIONAL-GRADE SENSOR】This weightlifting power measurement device uses a high-precision contact linear position sensor (rated load 15-20kg) with a measurement accuracy of up to 1.0mm, providing laboratory-grade data in the gym. The 70x70x35mm housing can withstand drops from the rack and repeated impacts, and can always maintain an error range of <1% even in full-force snatches or plyometric jumps.
• 【50H ULTRA-LONG BATTERY LIFE】Our smart speed tracker has a battery life 10 times that of ordinary gym trackers, equipped with a 300mAh capacity battery, which only needs 2 hours of charging to meet a week's training needs. The universal Type-C interface can be used with any mobile phone charger/power bank, and you will never miss any action due to a dead battery.
• 【REAL-TIME APP TRACKING】The VBT encoder uses advanced APP program control technology, allowing you to view training data in real time on your mobile phone APP. It supports viewing sports data such as speed,repetitions, fatigue detection, etc. Voice guidance will broadcast personal bests (PR) and movement techniques, and the screen projection function allows coaches to view data on TV/tablets during team training.
