Kaliber Gaming by IOGEARs RETIKAL Pro FPS Gaming Mouse is a pure-bred gaming beast, specifically built to dominate first-person-shooter games. The RETIKALs tournament-grade optical gaming sensor provides a huge step up in accuracy, allowing much more precise shots, especially when aiming-down-sight. In addition to its tournament-grade sensor, the RETIKAL also features a dedicated sniper button that changes mouse dpi while pressed, making head shots much quicker and easier. RETIKALs built-in memory stores up to five different mouse profiles, and allows you to change every single programmable option from dpi steps to macro functions with a single click. With five programmable steps up to 5000 dpi, RETIKAL is great for low sensitivity FPS gamers and has more than enough resolution for even high sensitivity 4K Ultra HD gaming.
