For years, JBM solutions have been integrated into software. There are now hardware solutions with JBM Ballistics solutions so you can have the same accuracy in the field without having to carry a bulky computer. These units solve the equations of motion and do not use approximate methods to find the ballistics solution.
A weapon mounted Optical Ranging Device & Ballistic Calculator (Powered by the JBM Solver) providing firing solutions at the current atmospheric conditions.
From the the RIANOV™ website: "With the simple motion of aiming your rifle and pushing a button, you will be accurately determining range to your target and calculating the perfect ballistics solution with the RIANOV doing all of the complicated mathematics."
The RIANOV™ can be ordered from a number of distributors including MountsPlus here.
