MagnetoSpeed's patented \u003cstrong\u003eelectromagnetic sensor\u003c\/strong\u003e technology delivers precise velocity readings by sensing the bullet as it passes through a pair of sensors clamped to the rifle's barrel, so there are no light gates, fragile optics, or downrange setups to fuss with.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eBuilt for everyday rifle use, the Sporter fits \u003cstrong\u003ebarrels from 0.5\" to 1.0\" in diameter\u003c\/strong\u003e, making it ideal for the contoured and tapered muzzles found on most sporting and tactical rifles.
