"I was new to the Dynavision D2 when Dr. Joe Clark and our vision training team introduced it to us as part of our vision training plan and was neutral on whether or not it would be of value to us.  We use the machine two to three times per week as part of our vision training program which I am completely sold on.  Our hitters claim to be able to pick up spin better and I have personally observed improved pitch recognition in our players.  They have improved noticeably in what pitches they swing – and don’t swing – at. The D2 vision training is challenging, fun, user-friendly and competitive – and the customizable programming keeps the players engaged and motivated.  At the end of the 2011 season, I asked our hitters about whether or not we should continue with the vision training.  The answer from them was an overwhelming “yes.”  The D2 will continue to be part of our program, and our plan is to get our pitchers on the device next.  Dr. Joe Clark is our resident expert on the science behind the technology and on how it all works; from my standpoint, I just know that it works and that I’m a huge fan.”

“I had already been fighting in UFC for a long time when I contacted Jim Leo at PitFit Training. I knew he was doing some things no one else was doing, so I paid a visit. He found some things I needed work on, and my reaction and vision response were at the top of the list. I’m blown away how much improvement I have had since using the D2. When it’s incorporated into a fighting-type circuit, it makes it that much more specific to a fight. ”

“That’s the kind of environment that we race in. There is a lot of noise; you are focusing on different things. You are having to verbalize something a lot of times about the car. So that’s actually a really good test.”

“I’m always on the prowl for new technologies. And there are a lot of technologies out there that I have seen and dismissed because they are too simple, too subjective, too easy to “game” or just wrong.  This year I came across Dynavision, a company that caught my attention with a sports vision training device called the D2. Based on results we’ve attained through our study at the University of Cincinnati, we believe the D2 can help us identify players who might not perform as well on game day, because of various distracting elements. And with continued, consistent training and testing, the D2 can actually be used to train athletes to focus and ultimately perform better on the field.”

“We feel the D2 takes the subjectivity out of the equation when it comes to grading the mTBI. It gives us a more valid score for return to play. Our pull from play is very simple; any head trauma and the player is out for the day until further assessment.”

“The D2 is definitely a step forward. There is so much more you can do with it. We had to be more creative with our old equipment to make it challenging for the athletes. The D2 forces you to be precise – it’s all about accuracy – and it is interesting to see how our athletes improve after using all the features and competitive-aspects of the unit.”

“There’s an important cognitive element to the Dynavision technology. Users have to quickly process the difference between green and red lights and only hit the red ones. We’ve found that the Dynavision is an excellent basemarker for concussion testing, because it detects and tracks cognitive and neurological changes with physical scores.”
