Logitech G303 Daedalus Apex

RGB Performance Edition Gaming Mouse

Part No: 910-004383

The G303 Daedalus Apex™ metal spring button tensioning system keeps left and right buttons precisely positioned to reduce pre-travel and backlash, delivering optimal response and feel. In-game actions remain fast and accurate.

    Advanced Optical Sensor with Delta Zero Technology

    Superior tracking for precision movements

    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.

    *Surface tuning requires Logitech Gaming Software

    Designed for the Performance Enthusiast

    You asked, we listened

    Logitech G took customer feedback from the community and used it to build a gaming mouse that meets the special performance needs of enthusiast gamers. We combined our highest-performing components, including the PMW3366 optical sensor, and put them in a lightweight, compact body.

    * Logitech Gaming Software is required to tune sensor.

    Six Programmable Buttons

    Customized to your style of gameplay

    Achieve great results with the default configuration straight out of the box. Or, set up one-button triggers for actions that typically require digging into menus. Put push-to-talk communications in easier reach. Temporarily down-shift DPI for sniping. Reassign any game command or multi-command macro to any one of six programmable buttons with Logitech Gaming Software.*

    * Logitech Gaming Software is required to program mouse buttons.

    Onboard Memory Profiles

    Take your settings with you

    Program up to three profiles for individual players or games, including keyboard macros, lighting, report rate and DPI settings. Take your settings to other PCs with no software required.

    * Logitech Gaming Software is required to program profiles.

    On-the-Fly DPI Switching

    Precision for every situation.

    Make the right moves in any game situation. Switch through up to five DPI settings, from pixel-precise targeting, 200 DPI, to lightning-fast maneuvers, up to 12,000 DPI, in 50 DPI increments with zero pixel rounding.
