Introducing the Proteus Spectrum, Logitech's most popular gaming mouse, with an advanced optical sensor for maximum tracking accuracy, custom game profiles, and repositionable weights. Now with customizable RGB illumination.

Control like you are in the game
Get maximum tracking accuracy from our most responsive optical sensor (PMW3366). Exclusive Logitech G Delta Zero™ optical sensor technology minimizes mouse acceleration and increases reliable targeting. Switch DPI modes on the fly—choose from five settings from 200 to 12,000 DPI*.

It’s your mouse the way you like it
Customize to your advantage. Five 3.6g weights come with your Proteus Spectrum. Use some or all of them in the positions where you like more weight, or less.

16.8 million colours to choose from
Adjustable RGB lighting lets you select from up to 16.8 million colors. Use Logitech Gaming Software to choose lighting colour and brightness to match your style, system or environment.

Adapts to your environment
Playing surfaces vary. You can get better accuracy by fine tuning the optical sensor in Proteus Spectrum to your playing surface. By tuning the mouse to your surface, you get improved precision and responsiveness.

Fingertip control
Program your favorite commands and macros to each of the 11 buttons. Select from thousands of profiles on your PC, or save your setting to one of the onboard profiles. Logitech Gaming Software (LGS) is required to change button programming. LGS is not required for onboard memory settings.

Be ready in an instant
Be an unstoppable force with Proteus Spectrum in either low or high DPI. Shift from headshot-precise 200 DPI targeting to lightning-fast 12,000 DPI maneuvers by shifting through up to five DPI settings per profile. Logitech Gaming Software (LGS) is required to set DPI preferences. LGS is not required for settings stored in onboard memory.
