This is what I want- Rangefinder that connects to my desktop with USB cable. Using software that comes with the rangefinder I can pre-load all of my ballistics data on it, for let's say 10 different loads. When I range something, the rangefinder will also calculate that angle, the direction I am aiming, everything. The unit will then tell me- in my choice of MOA, mils, IPHY exactly what my correction is for the range and angle that I am wanting to shoot based on the data I gave it with my computer. Do we really need to carry a freaking PDA? The math is not exactly something that needs to be done on a windows based unit. My dream device takes it out of the equation. I would rather carry a back up rangefinder and a range card than a PDA and my dream system would make the whole process faster- just shoot the laser and get the info. The military could probably use something like this.
