I was wondering why makers of lazer range finders such as the Fusion 16oo arc made by Bushnell persist in providing outputs that are calculations of bullet drop based on ballistic curves for assumed combinations of bullet and bullet speed. They give you an output in bow mode that consist of the actual distance to target, angle of shooting, and corrected horizontal distance. In gun mode they give you the actual distance to target, angle of shooting, and a calcualted bullet drop. This drop is only good for the assumed bullet/speed combo and other factors such as temperature, elevation, etc. If they just gave the same output for rifle mode as they do for bow, the shooter could calculate the required drops for his particular situation. What am I missing? Why not give the same output at the bow mode?
