“The PowerMaxx has allowed me to focus on my strength as a power pitcher. I have used it in my pre-season training. If I see my 4 seam fastball run off on my arm side, I know that the speed of the fastball is not where I want it to be.I need my fastball toridethrough the catcher. The PowerMaxx has helped me identify the reason why and correct it immediately. The PowerMaxx does what it says it will do. The boys have created a device that baseball has never seen before.“

“I use the PowerMax in my baseball training facility. The PowerMax helps kids understand where they need to bein their delivery and how important it is to stay balanced while pitching. It lets them make adjustments in realtime, which is something we have needed in baseball for a long time. I like it.”

“PowerMaxx is a game changer for our program. A key element on the mound is the ability to control yourbody with timing. PowerMaxx will help you understand how your body can move efficiently with correcttiming. The instant feedback helps our players become their own coach. Easy to use and no brainer for our program.”

"PowerMaxx provides a cost-effective way for pitchers to receive real time data about their delivery and mechanical sequencing. The portability of the device is excellent, and the setup/configuration time is very minimal.  Pitchers of all ages can benefit from the feedback that the PowerMaxx provides."

"When I first spoke to Marshall on the phone, you could hear his passion and willingness to help the game of baseball. His background and extensive knowledge have helped him create Powermaxx, a simple but essential device that instantly lets pitchers understand if their pitching delivery is on time. Being on time in the pitching delivery is one of the most critical measurables for current and future success. I extensively tested the Powermaxx in conjunction with our Delivery Value System. I found the values generated from the Powermaxx directly correlate to the body and arm being in a more supported orientation from the time the front foot strikes the ground to ball release. I’d encourage coaches and players to speak with Marshall and learn how the Powermaxx can help power their development to the next level. DVS Baseball will continue to collaborate with Marshall and his team on how to make pitchers better."
