The Aetronix Dry Fire Training System provides a complete and professional shooting range experience safely at home, eliminating the need for expensive and time-consuming range trips. This all-in-one electronic laser training target system features five distinct difficulty grade options (55mm, 40mm, 27.7mm, 16.8mm, and 8.5mm) with four extra center covers, allowing you to choose the proper film cover to set your desired challenge level. A clear built-in digital count display instantly shows the exact number of times you hit the target for highly personalized training and progress tracking. Designed for dynamic feedback, the target features responsive brightness and volume adjustment buttons, and it emits an alternating red and green flashing light along with a sound cue upon a successful hit, allowing you to customize the settings to fit different ambient lighting and indoor environments. Built for ultimate convenience, this portable electronic target features an eco-friendly built-in rechargeable battery that can be quickly powered via its Type-C charging port, complete with a practical low-battery alarm and clear charging indicator to solve the inconvenience of disposable batteries. It is engineered for multiple usage scenarios and can be placed on a table, floor, or mounted on a standard stand or tripod via the integrated 1/4-inch screw port on the bottom, while its powerful magnetic back design allows it to be securely attached to a refrigerator or any steel surface for versatile training sessions.
