Show HN: GhostDot – Airsoft Smart Red Dot HUD

Airsoft Smart Red Dot HUD

Advanced targeting computer and targeting system for precision airsoft sports

VIDEO DEMO HERE*

A next-generation smart optic that combines real-time environmental sensing, inertial tracking, and target computation to deliver professional-grade target correction in a compact, affordable package.

The Smart Target System is a revolutionary precision aiming solution designed for airsoft, and training applications. By integrating multiple sensors and real-time computational targeting, GhostDot provides airsoft with instant hold-over/hold-under corrections, wind compensation, and target tracking capabilities previously only available in 6th-Gen systems.

• 🎯 IMU-Based Target Tracking - Advanced IMU sensor provides stable target lock with sub-degree accuracy
• 🌪️ Real-Time Wind Compensation - Integrated anemometer calculates wind drift and displays MOA corrections
• 📏 Laser Rangefinding Integration - Automatic ballistic drop calculation based on target distance
• ⚙️ Configurable Ballistics - Support for multiple calibers (.177, .22, .25) with grain weight adjustment
• 🖥️ Multi-Mode HUD - Four specialized display modes for different operational scenarios
• 🔋 Low Power Design - Hours of continuous operation on a single charge
• 📡 Tactical Navigation - Geo-enabled waypoint navigation and team coordination display
• 🛰️ Motion Tracking - Advanced threat detection and situational awareness system
