The G303 Daedalus Apex by Logitech uses an Optical sensor, specifically the PMW3366, providing a DPI/CPI range of 200 - 12,000 dpi. This is combined with a 32-bit ARM processor. This results in a tracking speed of 300 ips, and a maximum acceleration of 40g. It uses a USB connection with a Braided cable. The G303 Daedalus Apex is considered to be an ambidextrous mouse. It weighs in at 127g grams with the cable and 87g without the cable and is approximately 115 x 65 x 37 mm (LxWxH).

At the core of G303 is our best optical sensor, the PMW3366. Built with Delta Zero technology, it delivers exceptional tracking while minimizing speed-related accuracy variance, commonly known as mouse acceleration, allowing for quicker reactions and more consistent targeting. For maximum responsiveness, the PMW3366 sensor has zero smoothing or filtering across the entire DPI range-even at high sensitivity. The sensor can be tuned, optimizing sensor parameters, not just LED intensity, to match the properties of your mouse surface for maximum high speed performance and lower lift-off distance.
