Hornady HIT Target Impact Indicator Features The Hornady HIT Target Impact Indicator is built around an internal accelerometer that senses the vibration created when a bullet strikes the steel target it is mounted to. The moment that impact is detected seventeen ultra bright red LEDs flash the letters H-I-T in Morse code giving the shooter an unmistakable unambiguous confirmation that the shot connected. That signal is strong enough to read with the naked eye at 1000 or more yards which means long range shooters no longer need a spotting scope or a second set of eyes just to confirm hits downrange. Because the flash pattern is a fixed code rather than a simple blink there is little chance of confusing an impact signal with sunlight glare or a loose connection. Each Black 9.5 inch indicator is designed to mount directly to a target stand using the included elastic band making setup quick at the range or in the field without tools or permanent hardware. Power comes from a built in rechargeable battery that is topped off through a standard micro USB cable so there are no disposable batteries to keep buying or swapping out between sessions. This listing covers a 2 pack letting a shooter outfit two separate steel targets or keep a spare charged and ready to go. For anyone who shoots steel at extended distances the HIT Target Impact Indicator turns a guessing game into a clear repeatable confirmation every time the target is struck.
