Stop adjusting – start hitting. Utilize the most effective ballistic software ever invented. Simple, intuitive and now integrated with smart sensors. With the tap of a button you can calibrate density altitude, Coriolis, cant and slope in real-time. Fully integrated with our new heads-up display, TRASOL enables you to capture video and snapshots, as well as track moving targets. TRASOL was developed for precision shooters who desire first round hit accuracy out to 5000 yards. FEATURES • Interfacing HUD • Automatic device sensor input • Unlimited equipment profiles • Cloud backup/sync for equipment data • Range up to 5000 yards (4572 meters) • Highly accurate trajectory prediction • Moving target speed tracking • Scope turret calibration • Cold bore adjustment • Light/dark color themes • Built-in tutorials HEADS-UP DISPLAY There is genius in simplicity. TRASOL is the first ballistic application to incorporate Heads-Up Display technology. By using your iPhone’s or iPad’s built-in camera and onboard sensors, TRASOL allows users to point their device at their target and automatically generate absolute accuracy solutions. The HUD environment has highly intuitive drag-and-drop tools for quick input of range and wind, and the device’s sensors do the rest. The HUD also allows tracking of moving targets to provide very accurate lead solutions. Photo/video capturing capability allows you to log your shots easily and share them with your friends. REFINED ACCURACY Utilizing proprietary algorithms, TRASOL is the most accurate ballistics calculator on the planet. No more need to alter manufacturer bullet data to get your hits; we developed new algorithms using Doppler radar data to create the most predictive flight path possible. In live-fire testing of TRASOL’s predictions the following results were documented (.338LM ammunition, using manufacturer's published data): • Within 0.1 MRAD up to 1400 yards • Within 0.5 meters up to 1700 yards • Within 1.1 meters at 2200 yards
