Mercury V75- Stealth Black（US Only）
8000Hz. 0.01mm Precision. Hall Effect. No Compromises.
The GravaStar Mercury V75-HE Gaming Keyboard - Stealth Black is the first Hall Effect keyboard from GravaStar — and it doesn’t ease you in gently. True 8KHz polling rate. GravaStar-customized Hall Effect switches with 0.01mm precision. Dynamic Rapid Trigger. Last Keystroke Prioritization. Adjustable actuation from 0.1mm to 3.5mm. This is a 75% keyboard built for players who know exactly what those specs mean — and why they matter.
Rated 4.6/5 stars by 123 verified buyers. On sale: $161.95 (was $179.95).
🔑 Key Features at a Glance
- True 8KHz Polling Rate — 8000Hz USB polling + 256kHz key-position scanning = 0.125ms keyboard latency
- GravaStar Customized HE Switches — Hall Effect magnetic switches with 0.01mm precision and 0.1–3.5mm adjustable trigger depth
- Dynamic Rapid Trigger — Activation and deactivation points adjust dynamically based on actual key travel, not fixed limits
- Rapid Trigger Mode — Instant reset on upward travel. No stiction. No waiting. Just re-press
- Last Keystroke Prioritization (LKP) + Snap Click — Intelligent simultaneous key press resolution for clean directional changes
- Adjustable Actuation Point — 0.1–3.6mm in 0.1mm increments. Tune every key to your playstyle
- Hot-Swappable Hall Effect Switches — Tool-free swap compatible with select TTC and Gateron magnetic models (S-pole down)
- Semi-Aluminum Construction — Metal frame backbone with premium plastic base. Rigid, lightweight, desk-ready
- 5-Layer Acoustic Foam — Minimizes keystroke vibration for a crisper, more satisfying sound profile
- 16-Mode Dual-Zone RGB Lighting — Dual independent RGB systems with multi-zone control
- 75% Compact Layout — Function row, arrow keys, and all the essentials. Maximum mouse room
- Wired USB-C — High-speed wired connection for zero-latency competitive play
⚡ True 8KHz Polling Rate
The V75-HE delivers a true 8000Hz USB polling rate paired with 256kHz key-position scanning — cutting keyboard latency to a near-instantaneous 0.125ms. That’s 8x faster than the 1KHz standard found in most gaming keyboards. At 1KHz, your keyboard reports its position every 1ms. At 8KHz, every 0.125ms. In competitive play, that gap is the difference between the input registering before or after the moment that matters.
🔮 GravaStar Customized HE Switches
Engineered for 0.01mm precision with an adjustable trigger depth of 0.1mm to 3.5mm, the GravaStar Customized Hall Effect switches use magnetic fields instead of physical contact — eliminating wear, eliminating bounce, and eliminating the lag that comes with traditional mechanical actuation. Perfect for clutch plays in CS2, precise aiming in Valorant, or any scenario where input accuracy is the margin between winning and losing.
Note: This keyboard uses south-pole-down (S-pole down) Hall Effect switches and does not support north-pole-down (N-pole down) configurations.
🎯 Adjustable Actuation Point
Most keyboards give you one actuation point. The V75-HE gives you 36. Adjust trigger depth from 0.1mm to 3.6mm in 0.1mm increments — shallow for lightning-fast combos, deep for deliberate precision. Eliminate accidental taps. Optimize response times. Tune every key individually to match your exact playstyle and the demands of each game.
⚡ Dynamic Rapid Trigger
Traditional switches have fixed reset points that create input delays. Dynamic Rapid Trigger eliminates this entirely — activation and deactivation points adjust dynamically based on actual key travel distance, not predefined limits. Keys engage instantly on press and release immediately on upward travel, enabling fluid, rapid-fire key repeats that are physically impossible with conventional switches. Essential for FPS aim, MOBA skill shots, and any scenario requiring split-second reactions.
🔄 Rapid Trigger Mode
Rapid Trigger Mode eliminates key “stiction” — the resistance that prevents keys from resetting instantly as they travel upward. With this mode active, keys reset the moment they begin moving up, so you can re-press and switch inputs faster than ever. No waiting for keys to bounce back. Execute rapid combos, skill shots, and direction changes with zero delay.
🎮 Last Keystroke Prioritization (LKP) + Snap Click
Two features that work together to eliminate “input chaos” in competitive play:
- LKP — Ensures smooth directional changes by always prioritizing your last-pressed key. Critical for games like Valorant and Apex Legends where clean WASD movement is the difference between a clean strafe and a missed dodge
- Snap Click — Intelligently resolves simultaneous key presses by favoring deeper inputs and auto-resetting shallower ones. So you never miss a command, even when your fingers are moving faster than your brain
🔧 Hot-Swappable Hall Effect Switches
The V75-HE’s magnetic switches are hot-swappable — swap out switches without soldering, without tools, without downtime. Experiment with different feels, replace worn switches, or customize individual keys. Compatible with select TTC and Gateron magnetic Hall Effect models (S-pole down configuration). Four GravaStar × Gateron Magnetic Jade Pro sample switches are included to get you started.
🔊 Silence Meets Sensation — 5-Layer Acoustic Foam
The V75-HE’s enhanced acoustic foam system minimizes keystroke vibrations, delivering a crisper, more satisfying sound profile and a smoother typing feel. Whether you’re grinding ranked matches or typing up a report, every press feels deliberate, every click stays clean, and your focus stays sharp.
🎨 16-Mode Dual-Zone RGB Lighting
Two independent RGB systems with multi-zone control and 16 dynamic lighting modes. Configure colors, effects, and zones through the web-based driver — no software installation required. The Stealth Black chassis makes every RGB effect hit harder.
💻 Durability Meets Modern Design
The V75-HE’s semi-aluminum construction pairs a sturdy metal frame for structural integrity with a premium plastic base for a lightweight, modern desk presence. Built to handle intense gaming marathons without flex, rattle, or fatigue.
