JBM Ballistics to Build Handheld Ballistics Calculator
JBM Ballistics (JBM), based in Las Cruces, NM, has provided free online ballistics info for the past 15 years. JBM Ballistics’ sophisticated algorithms deliver extremely reliable ballistics solutions. To complement its software, JBM plans to introduce a new hardware product: the BallistiComp.
Laster this year, JBM will unveil its new BallistiComp, a portable handheld ballistics computer that measures atmospheric temperature and pressure. Once your load data (Bullet BC, Velocity) is entered, the BallistiComp provides instantaneous drop and windage corrections for your load and shooting conditions. Calculated parameters include drop, windage, coriolis, drift and lead, plus terminal information including velocity, energy, time of flight and danger space. All of these parameters are displayed on an LCD display with backlight. Small enough to fit in your pocket, the BallistiComp is packaged in a rugged, watertight Lexan® case, measuring about 3″x5″x1″.
Why Not “An App for That”
Why would JBM produce dedicated hardware when there are good Ballistics Apps that can run on an Apple or Droid smartphone? Battery life is one reason. The single 9-volt battery should last for months (by contrast some smartphones need to be charged every DAY). Importantly, no connection to cell towers or the internet is needed. You could use this unit anywhere on the globe. Lastly, JBM wanted something that was inherently rugged and reliable. Smartphone touch screens are notoriously fragile.
How It Works
Using an 8-button keypad, you enter your firearm, ammunition and zero parameters into the system memory. BallistiComp then calculates the bullet drop and windage correction at the current atmospheric conditions, latitude and altitude (or calculated pressure altitude). BallistiComp continually measures the air temperature and pressure and provides constantly updated drop and drift numbers.
JBM has not yet disclosed a launch date or a suggested price for the new BallistiComp. However, you can download an Operators Manual to learn more about the BallistiComp. JBM cautions: “The manual is just a draft and may change during beta testing”.
