Stadiametric Rangefinder vs Calccis

Stadiametric Rangefinder is a range to the target estimation utility. It's designed to find distance to the target with a MIL, MOA, MRAD scale reticle fast and easy. The intuitive graphical interface was designed to replicate what you would actually see through your riflescope. Real-time calculations provide instant range measurements in yards or meters. You can also select any point in the world on map and location of the target on map and see how your target will look through eyepiece of your scope. Features: • Fast target distance estimation in both yards or meters • More than 3000 reticles. Including reticles from Carl Zeiss, Nightforce Optics, Kahles, Vixen Sport Optics, Premier Reticles, Primary Arms, Schmidt and Bender, SWFA, U.S. Optics, and Vortex Optics, US Army, USMC mil-dot ( see list of reticles supported here http://jet-lab.org/chairgun-reticles ) • More than 80 targets (IPSC, NATO, EIC targets). Also you can add targets for shooting created by you • Target size presets • Adjust for magnification setting (second focal plane) • Calculator for MOA at distance • Click value validator • Ballistic coefficient from 2 speed calculator • Angle units converter • Speed units converter • Weight units converter • Pressure units converter • Length units converter • Torque units converter • Air laboratory (Air Density, Density Altitude, Relative Air Density (RAD), Dew Point, Station Pressure, Saturation Vapor Pressure, Virtual Temperature, Actual Vapor Pressure, Cumulus Cloud Base Height, Dry Air, Dry Air Pressure, Volumetric Content of Oxygen, Oxygen Pressure) • Light/dark/gray color themes

Calccis is a reverse polish notation (RPN) calculator. It supports basic arithmetic, trigonometrical, logarithm and exponent calculations for real, fractional, and complex numbers. Degrees and radians can be used for trigonometrical functions. You can perform matrix calculations, too. There is an undo stack, which supports undoing and redoing the 100 latest operations. Calccis does not copy or mimic any existing physical calculators. However, the operation of the stack has been influenced by how the stack works in the 1990s Hewlett-Packard HP-48 family of calculators.
