“Coming soon, BallistiComp, a portable hand held ballistics computer that measures the atmospheric temperature and pressure and provides instantaneous drop and windage corrections for your load and shooting conditions.
BallistiComp provides a simplified interface to the proven JBM ballistics algorithms which gives you the information you need to make the shot with confidence.
How It Works
You enter your firearm, ammunition and zero parameters into the system memory through the easy to use interface. BallistiComp then calculates the bullet drop and windage correction factors (among other parameters — see below) at the current atmospheric conditions, latitude and altitude (or calculated pressure altitude). BallistiComp continually measures the atmospheric temperature and pressure and provides updated correction factors.
BallistiComp is packaged in a small, watertight, impact resistant Lexan® case. It’s simple to use eight button interface is fast and intuitive.
Features
Calculated parameters include drop, windage, coriolis, drift and lead, terminal information including velocity, energy, time of flight and danger space. All of these parameters are displayed on a fast, easy to read LCD display with backlight. A list of input and output parameters are listed below.
BallistiComp is powered by a single nine volt battery. No rechargable batteries required. No special connections to a computer and no other software is required. BallistiComp is designed to be completely programmable in the field.

Beta testers wanted!
JBM will be looking for beta testers for the new product within a couple of months. If you would like to be one of the first to use the BallistiComp, send us an email and tell us about the kind of shooting you do, how often you shoot and your familiarity with computers. There are no wrong answers as we are looking for a diverse cross section of the shooting community. If selected to be a beta tester, you will be required to sign a non-disclosure agreement to enter the testing program.”
