Optical Sensor with Delta Zero Technology

At the core of G303 is the optical sensor, the PMW3366. Built with Delta Zero technology, it delivers higher tracking while minimising 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, optimising sensor parameters, not just LED intensity, to match the properties of your mouse surface for maximum high speed performance and lower lift-off distance.

Designed for the Performance Enthusiast

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

Metal Spring Button Tensioning System

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.

Programmable RGB Lightening

Customise from 16.8 M colours.

Bring your mouse to life with 'breathing' light patterns or set your lighting to sleep when you aren’t using your system. Choose lighting colour and brightness to match your style, system or environment. Daedalus Apex lighting can be customised from a palette of up to 16.8 million colours.

Durable and Lightweight

A gaming mouse that lasts as long as you do.

Designed for comfort and durability, Daedalus Apex performance gaming mouse is rigorously tested to make sure it can stand up to even the longer gaming sessions. The left and right buttons have been successfully tested for 20 million clicks, the equivalent of a pro gamer training 10 hours a day, every day, for 2 years. Sturdy yet lightweight materials and flexible braided cable ensure your gaming sessions are comfortable from start to finish.

Surface Tuned Performance

Adapts to your environment.

Fine tune the optical sensor in Daedalus Apex to your playing surface to reduce lift-off distance and enable better accuracy, precision and responsiveness.

G303 Daedalus Apex is pre-tuned for Logitech gaming mouse pads, G240 and G440. Add a mouse pad for higher accuracy.

Six Programmable Buttons

Customised to your style of gameplay.

Achieve better 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.

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.

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.
