Razer Launches Basilisk V4 Pro Gaming Mouse With 50K Sensor

Razer has expanded its ergonomic gaming mouse lineup with the release of the flagship Basilisk V4 Pro and the value-oriented Basilisk V4 HyperSpeed. The new flagship model, priced at $169.99, introduces a suite of hardware upgrades including a 50,000 DPI optical sensor and a redesigned scroll wheel system. Alongside the mice, Razer introduced the Mouse Dock V2 Pro, a $69.99 accessory that provides magnetic wireless charging and serves as an 8,000 Hz wireless transceiver.
Hardware and Sensor Upgrades
The Basilisk V4 Pro features the new Focus Pro 50K Optical Sensor Gen-3, capable of 50,000 DPI sensitivity, 930 IPS tracking, and 90 G acceleration. Razer has also integrated its fourth-generation optical mouse switches, which the company claims offer 12 percent lighter actuation and are rated for 100 million clicks. The mouse retains the series' signature ergonomic chassis with a dedicated thumb rest but has been engineered to be 12 grams lighter than its predecessor.
The Basilisk V4 Pro weighs 100 grams in black.
Connectivity is managed through HyperSpeed Wireless Gen-2, which supports a native 8,000 Hz polling rate. The device offers flexible pairing options, supporting up to five devices across HyperSpeed, Bluetooth 6.2, and a wired connection. Battery performance is rated for up to 200 hours when using the HyperSpeed link at 1,000 Hz, extending to 275 hours over Bluetooth 6.2.
Enhanced Control and Scroll Functionality
A central feature of the V4 Pro is the HyperScroll Tilt Wheel Gen-2. This component offers four distinct scrolling modes: a standard 24-step tactile mode, a new 48-step Precision Tactile mode for finer control, a Free-Spin mode for rapid scrolling, and an adaptive Smart-Reel system that switches modes based on scroll speed. The exterior has been updated to include 14 customizable controls, featuring a repositioned multi-function trigger, a third side button, and an M1 edge button.
Software enhancements include a new Perfect 180 feature, which allows users to snap their view 180 degrees with a single click, a tool Razer notes is designed for low-sensitivity gaming. The Mouse Dock V2 Pro complements the setup by consolidating peripheral connectivity into a single USB port while providing magnetic charging and 8-zone Chroma underglow lighting. The budget-focused Basilisk V4 HyperSpeed, priced at $109.99, utilizes a 33,000 DPI Focus X 33K sensor and offers up to 140 hours of battery life on HyperSpeed wireless.
Razer puts the click latency of the Basilisk V4 Pro at 8,000 Hz at an average of 0.204 milliseconds, and users who consistently use the full 8,000 Hz polling rate can expect a runtime of around 54 hours.
What to look for beyond the sensor number
A 50,000-DPI sensor specification describes the upper end of a setting, not a sensitivity that most players need. Shape, weight, click feel, lift-off tracking and wireless latency tend to influence daily play more directly. The Basilisk V4 Pro's suitability will depend on hand size, grip style and the software needed for customization. Buyers should also compare battery life under the lighting and polling-rate settings they intend to use. A high maximum sensor resolution is not, on its own, evidence that a mouse delivers better aim.
