The Field Ops watch includes our revolutionary SureShot calculator. In a partnership with Horus Vision, makers of proven long-range ballistic software, we give you the ability to input thirteen critical variables needed for long range shooting solutions quickly and easily. Shooting solutions are provided in Mils, True Minute of Angle (TMOA) and Shooters Minute of Angle (SMOA). Weve beefed up the pins, sealed the watch for 1 meters of water resistance and given you a switchable backlight so you can see your data when you need it and turn the light off when you dont.The Field Ops Watch has all the features youll need for work and play. Weve included digital day and date, and two digital time zones. Along with an audible alarm, there is an hourly chime, a countdown, timer and you can check your lap times with a digital chronograph. Weve included an omni-directional bezel along with a backlight. The Field Ops Watch also has a fully functional digital compass which can be adjusted for true north readings. And last but not least, weve given you a full function ballistic calculator. The SureShot calculator accepts thirteen critical shooting variables to give you point of impact shooting solutions out to 1 meters. Input your known ballistic data (bore height, ballistic coefficient, muzzle velocity and zero range), then add your environmental data (range, temperature, altitude, inclination) and the SureShot calculator will give you a shooting solution in MILS, TMOA or SMOA. You can even get your solution in clicks for both windage and elevation. The calculator is very easy to use and most of the variables can be put into the Field Ops Watch before going out to the field. The Field Ops Watch has a high-density polycarbonate case which is lightweight and tough. The mineral glass crystal face is scratch resistant and reduces glare. Weve included an extended length band so that you can wear your watch over outerwear or a glove.
