► Mercury V75HE - Mercury V75HE
Introducing the Mercury V75HE, featuring an 8000Hz USB polling rate and 256kHz key-position scanning for near-instant latency of 0.125ms. The GravaStar x Gateron Magnetic Jade Pro Switch offers 0.005mm precision with adjustable trigger depth (0.1mm–4.0mm) to eliminate lag and improve control. The adjustable actuation point (0.1mm steps) allows customization for different playstyles—shallow for fast combos, deep for accuracy. The dynamic rapid trigger adjusts activation/deactivation points based on key travel, enabling fluid rapid-fire key repeats.
