Mantis
The entry MantisX sensor: same muzzle-trace and trigger-control analysis as the X3, restricted to dry fire.
The X2 is the floor of the MantisX line and the honest recommendation for a lot of shooters. It clamps to the accessory rail, watches how the gun moves through the press, and tells you what your trigger finger did to the muzzle. That is the entire MantisX value proposition, and the X2 delivers it at the bottom of the line.
What you give up is live fire. Mantis's own model comparison lists the X2 as built for dry fire use only; the X3 is the model that adds live-fire sessions and the ability to compare dry and live data side by side. Everything else the two share: muzzle trace, trigger-control analysis, a shot timer, historical tracking, coaching tips keyed to your proficiency, the drill and course library, daily challenges, groups, and per-firearm tracking. The app is free with lifetime access and no subscription.
Two practical notes. The sensor needs somewhere to mount, so a pistol without an accessory rail needs one of Mantis's MagRail floor-plate adapters or a universal adapter, sold separately, where the X10 Elite includes both a BR7 rail and a Universal MagRail in the box. And because motion analysis works by measuring the gun rather than reading a target, the X2 pairs naturally with a laser kit rather than competing with one; Mantis designs it to run alongside Laser Academy and Blackbeard.
