Two phones over local Wi-Fi — the sensor phone sits meters from the target while you shoot from real distance. With a mid-point travel router, handgun drills tested at 30–50 m and rifle drills up to ~100 m. Your eyes focus at true range, where small sway means a large miss — the refinement that actually transfers to live shooting.

LaserLock scans only your yellow ROI zone and ignores everything outside it. Shade just the target (even a simple cardboard box works) and it doesn't matter if the entire field between you and the target is in blazing sun — detection stays clean, false hits stay out, and battery lasts longer because the app processes only the pixels that matter.

ROI-focused processing instead of full-frame scanning means longer sessions and cooler phones. With camera zoom set so the target fills the frame — keeping the laser dot visibly sized instead of a vanishing speck — standard laser cartridges detect reliably at typical training distances, and brighter cartridges extend range further where they are legal to own and use in your jurisdiction.

⚠️ Check your local laser output limits before buying any cartridge. Maximum permitted laser output varies by country and region, and is strictly enforced in many jurisdictions. LaserLock neither encourages nor accepts responsibility for the use of lasers exceeding local legal limits.
