MagSpeed Electromagnetic Scrolling

Switch between deliberate line-by-line movement and fast free scrolling when working through a long document or spreadsheet. The electromagnetic MagSpeed wheel gives the mouse a clear role in research, editing and office work, where reaching a distant section quickly matters as much as making a precise adjustment.

Darkfield Tracking up to 4,000 DPI

The original Darkfield sensor adjusts from 200 to 4,000 DPI in 50 DPI steps. Choose a pointer sensitivity that matches your screen arrangement and hand movement. This is the original MX Master 3 sensor specification, suited to everyday desktop navigation and detailed document or design work.

A Thumb Wheel and Seven Buttons

A separate thumb wheel supports horizontal navigation, useful when a timeline or spreadsheet extends beyond the screen. Seven buttons provide controls around the main grip. Supported Logitech software can adapt available functions to the application, helping arrange frequent actions around a familiar hand position.

Connect without a Fixed Mouse Cable

Bluetooth and 2.4 GHz Unifying connectivity provide two ways to connect to compatible computers. Easy-Switch supports moving between paired devices, while supported Flow software can help with multi-computer work. Software functions and operating-system support should be checked for the equipment used at each desk.

USB-C Rechargeable Power

A built-in rechargeable lithium-polymer battery is rated for up to 70 days under Logitech test conditions. A one-minute quick charge can provide up to three hours of use under the stated conditions. USB-C handles charging, keeping regular disposable battery replacement out of the routine.
