Inaccurate Readings

I reached out via email to “b4” and didn’t receive a reply on how to resolve my issues. It has been over a week now with no response. I contacted them through their support link on the app.

I have tried baseballs and softballs. I have tried lower pitching and higher pitching. I have switched batters. I have double and triple checked the setup and measurements. Nothing I have tried has lead to accurate Exit Velocity (EV). We’re hitting balls over 300’ fences and the highest EV reading we get is less than 65.

I canceled the premium plan today. I’m seeing better readings on the reels than we get and I feel like I’ve put more effort into figuring this out than most would.

Excellent teaching tool

Exit Velo seems close enough, launch angle right on point. Great tool for seeing mechanics of head tilt, center mass, and stride. Will def use for lessons and individual hitting coaching.

Good but bad

It seems like it works for certain people and i don’t know the conditions it’s supposed to work at but the ev seems incredibly off.
