    This bat was beautiful and had a ton of pop right out of the box. I’ve hit with it live once and it felt good. It has a slight taper and is a great bat with great feel

    used this as the first wood bat I ever purchased, Good for contact hitters, it did break on me about 3 months into use, hit it off of the end. Died a hero. Would absolutely recommend this bat

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.
