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 (sine, cosine, tangent, arcsine, arccosine and arctangent simplify complex design and construction-math).

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; determining number of on-center studs for an entered length; and right angles. It also offers advanced solutions for circles, arches, columns, cones, pillars, windows and post-holes arcs, circumference, and segments.

Additional features include a large multi-position tilt display LCD, ability to custom define your preferences (such as fractional settings), a "paperless" tape that lets you review the previous 20 entries to double-check your totals, and accumulating memory with three additional memory storage locations. It's powered by a single 3-volt CR2032 lithium battery, and the Construction Master Pro has an auto shut-off feature that turns the calculator off after about 8 to 12 minutes of non-use.
