The LaserLyte Target Trainer records and stores where the installed laser hits the target after a dry fire. It does not, however, display the location of the hit immediately. After you’ve taken as many shots as you would like, you simply point the laser and dry fire at the small circle that says ‘Display’ and it shows the locations of your hits. To reset the Target Trainer, you just point the laser and dry fire at the small ‘Reset’ circle. LaserLyte designed the Target Trainer this way to simulate the delayed feedback that you would receive while shooting at the range. It runs off of 3 AAA batteries.
