The HIT Impact Indicator means never guessing again. Attach it to a target stand and it easily distinguishes impacts by blinking H-I-T in Morse code. Being on target is six dots and a dash away. Ultra-bright light indicates bullet impact on distant steel targets, visible up to 1000+ yards with naked eye. Easily attaches to most stands with included elastic band. The indicator is rechargeable using micro-USB, morse code "H-I-T" blinks for impact distinction, the accelerometer detects bullet vibrations for activation.
