In the office or at the drafting table, the Construction Master Pro--Desktop helps get the job done right the first time! Unlike a regular calculator, the Construction Master Pro--Desktop has large and intuitively labeled ''construction keys'' and a format that is so simple, even the novice user will find it easy to solve hundreds of problems directly in feet, inches and fractions! Plus, its extra large LCD and big keys make it even easier to use!
Dimensional Math & Conversions: Works in all dimensional formats: quickly add, subtract, multiply, divide and convert in feet-inches-fractions, decimal feet, decimal inches, inches and fractions, yards, meters, centimeters, millimeters, board feet, as well as square and cubic formats.
Handles all fractions-1/2's, 1/4's, 1/8's, 1/16's, 1/32's, 1/64's : Work in fractions for all sorts of dimension problems. You can even set fraction denominators to display your desired accuracy (in above fraction formats).
Complete Right-Angle SolutionsInstant square-ups, slopes, rafter length and rake wall solutions. No more formulas or memorization of Pythagorean theorem! Pitch, Rise, Run, Diagonal/Common, Hip/Valley and Jack keys find rafter lengths. Also solves for lengths of irregular Hip/Valley and Jack rafters, as well as rafter cutting angles!
Automatic Stair Calculations Finds number of risers, treads, riser height, tread width, and any underage or overage for stairway layouts. Now calculates an entire stairway based on the entry of a floor-to-floor rise. Also calculates stringer length and angle of incline.
Complete Circle Solutions Solves circumference, circle area, arc lengths for columns, post holes, pillars, as well as solving circular segments.
Instant Area & Volume Calculations For fast & accurate material estimates, such as volume of concrete.
Trigonometric Functions Sine, cosine, tangent, arcsine, arccosine, arctangent have been added, in case you need additional trig. solutions.
Weight per Volume Key Lets you convert between weights (lbs, tons, kg) and find weights of any material (e.g., tons per cubic yard).
Board Feet KeyHelps estimate material amounts and costs of lumber.
“ Smart ” Fraction Setting Saves keystrokes by entering preset fraction denominators for you, from 1/2 to 1/64.
User-Set Preferences Allows user to set preferred dimensional formats and customize rafter/rake wall calculations.
Paperless Tape Lets you review the last 20 entries, for double-checking answers.
Standard Calculator Works as a regular math calculator, for your everyday math needs.
