The rapid advancement of technology on all fronts has yielded some fascinating mash-ups to make life easier for small groups of people with specific needs and the US$15 KAC Bullet Flight 1.0.0 iPhone app and rifle iPhone mount are a case in point – they are just perfect for the sniper/hunter. One of the many skills of the modern day marksman is mathematics – to measure or estimate the range, cross winds, and calculate the allowances needed for one shot to hit its target after travelling up to 2000 yards. Bullet Flight turns the iPhone into a handy, touch screen, ballistics computer using the iPhone’s accelerometer to calculate angles, providing highly detailed, very quick solutions out to 2000 metres. The KAC mounting attaches an off-the-shelf Otterbox ruggedising case. You can also download different weapon and ammunition profiles (it comes with three) and even subscribe to highly detailed weather and forecast information, not to mention listen to music whilst you await your quarry. BTW – this scares us to death!
