The QMD4 Billiards Stroke Trainer/Analyzer is an innovative billiards training aid designed to help you find and fix the flaws in your pool stroke. A new way to practice, let QMD4's precision and accuracy take your game to the next level.

The highly sensitive QMD4 Bluetooth enabled device is attached to your pool cue and transmits detailed 3-D information about your stroke to the free QMD4 app on your iPhone or iPad.

QMD4 features automatic shot recording/playback with a stroke velocity chart and cue tip view. Instant, audible 'as you stroke' alerts pinpoint problem areas in your stroke. Comprehensive metrics are generated for each practice shot allowing in-depth analysis to identify flaws, tendencies and to compare your progress with prior practice sessions.

The QMD4 is the forth generation of QMD Stroke Trainers with improved hardware and software features. The QMD4 device may be ordered from www.theQMD.com.
