Easy-to-see at your desk or in the field
Calculate dimensions
The Construction Master Pro Trig - Desktop is perfect for completing layouts, bid and estimates. You'll be able to work in and convert between all building dimensional formats-yards, feet-inch-fractions and metric-including area and volume, and it also comes with a full trigonometric functionality.
Plus, you will be able to calculate complete stair calculations, built-in right angle functions, area, volume and perimeter solutions, roof function, custom rafter, compound miter angles, advanced circular solutions and more.
Built-in time-saving functions
The Construction Master Pro includes a number of built-in time-saving functions, including calculations for risers, treads, stringer length, and incline angle; how many 4x8, 4x9 or 4x12 sheets are needed to cover an area; jack rafter results for regular and irregular pitch roof; and right angles. It also offers advanced solutions for circles, pillars, windows and segments.
Everything you need
