How It Works: The Kizuna GTS7 Pro Sports Max uses bioimpedance analysis to measure body composition by sending a small, undetectable electrical current through your body when you complete the circuit with two fingers on the bezel. The temperature sensor takes readings every 5 minutes to establish your personal baseline and alert you to potential fever states. The sleep apnea detection works by combining blood oxygen readings with respiratory rate data.

Benefits: The Kizuna GTS7 Pro Sports Max excels at preventative health monitoring, potentially identifying issues before they become serious problems. The body composition analysis provides a more useful metric than weight alone, helping you track muscle gain and fat loss during fitness journeys.
