## Overview

The Just Jump System is a portable, battery-operated athletic testing tool that accurately measures jump height, hang time, ground contact time, foot quickness, and explosive leg power. It records and averages data over multiple jumps, providing fatigue analysis to optimize training and rehabilitation. Compact and easy to use, it offers pro-level insights at a fraction of the cost of traditional force plates.

## Description

Hand held computer displays height and hang time for one jump, ground contact time for one jump and average height and hang time for four jumps. Computes foot quickness (shuttle runs and dashes) and explosive leg power rating. Records 60 jumps, then averages heights, contact times and leg power for first and last 15 jumps, in addition to a fatigue factor rating. Extremely accurate and eliminates guesswork. Portable, easy to operate, sets up in seconds. Use for testing athletic performance as well as charting rehabilitation. Battery operated, 1 year warranty. (27" x 27" mat with hand held computer)

Review: Best Option - Works good. Hard to cheat and a monkey could use it. And at $500 it is a lot cheaper than $20,000 for force plate that correlates between 0.90-0.95 with this timing pad. And it is comparable price to a Vertec, but this is much easier to do sports teams when you have 8 minutes to get 15 kids through vertical jump tests during fitness testing and adds some other training versatility.
Review: Five Stars - The Just Jump System has been a great addition to my assessment process. It's fast and easy to understand.

### ⭐⭐⭐ Solid but room for improvement
*by P***E on August 6, 2023*

Durable and gets the job done. We use at our private facility. The grooves can be rough on the hands for plyo push ups. Would also be cool if the controller was rechargeable instead of battery operated. Would like to see the price come down as well, especially with the emergence of other options.
