Mantis X2 Dry Fire Training System vs Mantis X3 Dry Fire Training System

Both are the same tiny 1.3 x 1 x 0.75 inch Bluetooth sensor that mounts on a rail or slide and logs your draw, trigger and recoil trace in the Mantis app. The X3 is the newer unit and the one most owners describe as a worthwhile training tool with rich movement data and no ammo cost; the X2 is the earlier version with the same form factor and core shot-tracking. Buy the X3 for the current app support and the feedback owners praise; pick the X2 only if you find it and want the basic trace. Neither is a build-quality upgrade over the other; the difference is generation and software.

• Choose the Mantis X2 if you want the entry-level Mantis sensor and only need core shot and draw tracking in the app.
• Choose the Mantis X3 if you want the newer generation with the fuller movement data and training modes owners call effective.
