    Love the thick handle and Barre barrel, but the tape is very slick and doesn’t provide a very good grip. With the thick handle and barrel the bat is not as likely to break. Great bat, bad tape.

    I got this yesterday and have been absolutely raking. It's so dope and it looks even cooler with the ink dot. I got maple and would totally recommend this to anyone in middle school though college even to the MLB

What is a Smart-Ready Knob?

Marucci’s Smart Bat technology allows Diamond Kinetics’ SwingTracker sensor to be securely fitted inside of the actual knob of a Custom Pro Model bat. By selecting Smart-Ready knob, you’re authorizing Marucci’s wood production team to carve out part of the knob and install a dual-locking mechanism to firmly hold your SwingTracker sensor in place, allowing for the most accurate data possible.

Don’t forget the sensor!

The Diamond Kinetics SwingTracker sensor captures your most precise swing data using 11 different metrics in four core swing categories: speed, power, quickness, and control, then sends it to the SwingTracker app through a paired iOS device via Bluetooth. View metrics in easy-to-read graphics and charts or sync with a unique 3D image or video of your swing.
