For Christmas two years ago my fiance got me a 5.11 Field Ops Watch featuring a SureShot ballistic calculator. I thought it was a very cool gift but had my reservations about how accurate it would be. After opening the box I quickly started playing with it. The directions were easy to follow and I soon had everything set and digital compass calibrated. I entered my ballistic information into the program and started testing it versus my hard data. I was surprised to find the predictions from the watch were very close and often the same as my D.O.P.E.
With my loads ballistic profile entered into the watch I was ready to hit the range. For practice and local matches I didn’t use the watch much other than to tell the time. I stuck to using the information I had recorded in the past. It was during a AZ PRC match in Prescott, Arizona that the convenience of the 5.11 Field Ops Watch struck me. It was February, we had snow on the ground. Shortly after arriving we took out the Kestrel to start getting atmospheric conditions. Once we had them I entered it into the watch. The location of the match was 8,000 ft. above sea level. It isn’t a traditional range and you find your self hiking around in the woods. Density altitude was 7,500 feet. That is considerably higher than was we see at our home range so I entered the D.A. into the altitude field, temperature was a cool 40 degrees. Using my hard data and consulting my watch I was able to accurately predict the needed elevation to score hits in those conditions. I have never shot a competition before with such drastically different conditions than to what I was accustomed to at home.
