发明名称 Tech-track
摘要 This device is easily detachable. When the arrow makes impact, the dart with the transmitter remains in the target. The impact activates the transmitter which puts out a signal that can be picked up by the receiver. Because the device is small and ver light and has a counter-balance, it won't interfere with the accuracy and the flight of the arrow. This allows the archer to find the game faster and easier.
