The D2™ is a cutting-edge, FDA cleared, high performance evaluation and training device that records response to visual, gross motor and neuro-cognitive tasks. The user trains peripheral awareness, eye-hand coordination and visual reaction time. While reacting to the lights, the eyes focus in the middle of the light board at the tachistoscope (T-Scope). The T-Scope is the key to vision training success. In High Performance athletes, The Dynavision D2™ light board measures performance and records the data to track improvement. The training routines are also customizable, with sport-specific programs for athletes of every level. Performance will improve in areas such as the peripheral alert state, concentration, reaction speed, physical development, decision making, visual processing while in increasing levels of stress, speed and the recognition repertoire.
