The importance of explosiveness in sports calls for multiple tests for evaluating power (Stockbruggar & Haennel, 2003). Overall peak power is one of the most important performance variables (Stone et al, 2003), and a primary measure of power is the ability to perform well at the vertical jump. The purpose of this project was to investigate the validity and the reliability of the V-scope (VS-120) for measuring vertical jump height. Subjects were twenty-two students from a small Midwestern university. All subjects completed a test protocol which consisted of performing three vertical jumps to achieve their maximum height. All jump heights were measured using a Vertec and the V-scope. A dependent t-test and a correlation test were performed and revealed that there was a significant difference (p = .003) between the values collected by the two devices, and there was a moderate correlation (r = .636) between the values. .
