1. Overview

1.1 AtragMx from Horus Vision

Horus ATragMX software considers atmospheric conditions, gun data, ammunition, range, speed and muzzle velocity to calculate precise aiming solutions with "come-up" results – and even accounts for Coriolis and spin drift effects. ATragMX, loaded on a handheld computer made by TDS Recon, is easy to use and lightning-fast. The Recon meets the rigorous MIL-STD-810F military standard for drops, vibration, humidity, altitude and extreme temperatures.
