I have been using BatSense for 2 months now. It's been really helpful from what I have seen. It gives me data of what I see from my eyes. It measures if something is off in terms of timing, impact, angle etc. BatSense has really changed the way I approach my lesson plans. BatSense give clear picture, if the timing was off, or the way they hold their bat. That helps in seeing the mistake and correct the players.
One of my favourite features is Speed Impact, it tells me a lot. It tells me if they played too early or if they are going for the ball, if they are holding their bat back. Also, it allows me to see when they are not using their energy properly in a shot, that's definitely a key feature for me. I also like the impact angle. I know if they play too early or late that helps me to change their game. So when they go into power hitting I want to get them in the right angle hitting the ball.
When you play the hook shot it shows you the bat angle whether you're hitting with open face, or coming under the ball and slicing it or if you are playing it horizontally. All of these features have helped me in my training sessions and what I am doing at the time. It really helps my students in those regards.
