Play Without Limits G603, with the revolutionary HERO sensor and LIGHTSPEED wireless technology, delivers exceptionally accurate and consistent performance and a breakthrough in battery life setting a new standard in wireless gaming. Next-Gen HERO Gaming Sensor HERO is a revolutionary new optical sensor designed by Logitech G to deliver class-leading performance and up to 10 times the power efficiency (compared to previous gen). HERO sensor delivers exceptionally accurate and consistent performance with zero smoothing, filtering or acceleration from 200 to 12,000 DPI. Magic Quadrant HERO is a true breakthrough innovation in sensor technology providing revolutionary performance and efficiency. It’s the first of its kind to enable high-performance and long-lasting wireless gaming mice. 10x Efficiency HERO utilizes a smart power management system to continuously adjust frame-rate processing based on mouse speeds. This allows for optimized by constantly managing and minimizing power consumption for up to 10x efficiency compared to previous generation sensor. HERO IN ACTION HERO delivers accuracy at velocities over 400 IPS across the full DPI range—from 200-12,000—with zero smoothing, acceleration or filtering. HERO sensor gives players unsurpassed responsiveness, precision and power efficiency. LIGHTSPEED Wireless Through end-to-end engineering and design, Logitech G developed a robust wireless solution to solve the fundamental problems of latency, stability, and connectivity. The end result is LIGHTSPEED, a pro-grade wireless solution, that achieves wired-like performance. 1 ms Wireless Achieved Logitech G engineers worked through a complete end-to-end technology optimization from sensor to firmware, circuitry to antenna design. We tested and refined each component, focusing on the slowest link until nothing was slow. Advanced Power Management Quickly switch between HI and LO modes with the flick of a switch. In HI mode, G603 delivers peak performance with LIGHTSPEED 1ms report rate and up to 500 hours of non-stop gaming. When not gaming, simply switch to LO mode and extend battery life. LO mode reports at 8 ms for up to 18 months of use with 2 AA batteries. Connect to Multiple Devices Dual connectivity with LIGHTSPEED and Bluetooth® allows you to connect to and control multiple devices across platforms. Easily toggle between the two connected devices with a press of a button. Amazing Battery Life G603 wireless gaming mouse delivers up to 500 hours on 2 AA batteries—twice as long as our previous generation. Even with a single battery the G603 can last through up to 500 matches of League of Legends®. You can also choose which side to place a single battery with no impact to performance for custom balancing. When battery is at 15%, both LED status indicator and Logitech G HUB will notify you before the critical moment. Six Programmable Buttons The G603 wireless gaming mouse can be fully configured to match your preferences. G603 comes with 6 programmable buttons including on-the-fly DPI shifting through up to 5 sensitivity settings. Use G HUB to assign custom commands, configure macros (sequences of clicks and keystrokes to simplify in-game actions and quickly execute complex tasks), store configuration profiles in the onboard memory, and more. Wireless Gaming Desktop Pair the G603 gaming mouse with the G613 wireless mechanical keyboard to acquire the complete wireless gaming desktop solution. G613 features advanced LIGHTSPEED wireless, Romer-G mechanical key switches, programmable G-keys, and more gaming features.
