A Bluetooth® enabled revolutionary electronic cue training device for improving player performance. Simply slide the DigiCue BLUE onto the butt end of your cue, push the power button and then play your game of choice. This device is like having your own personal coach giving you immediate feedback on every shot that you shoot by alerting you with vibrations when it detects any inconsistencies in your stroke when you hit a ball with your cue and sending that information to your smart phone or tablet and giving you detailed results and stats about multiple aspects of your game.
The DigiCue BLUE will Detect:
• 4 unique settings: beginner, intermediate, advanced and custom modes
• Discreet and lightweight (less than an ounce)
• Can be used when you train/practice and also during competition*
• Comes with two sizes to fit the vast majority of Pool, Snooker, and Billiard cues
• Automatically shuts off after 5 minutes of not hitting a ball to maximize battery life
• Battery included
• Made in the USA
