CONSTRUCTION MASTER®PRO
USER’S GUIDE
This User’s Guide helps you solve common construction math and ma-
terial estimation problems using the latest Construction Master®Pro
calculators—five of the most powerful feet-inch-fraction calculators to
date:
The Construction Master Pro Series —
1. LT (#4030)
2. Handheld (#4060)
3. Trig Plus III (#4075)
4. Desktop (#44060)
5. New! Desktop with Printer (#44065)*
*CI now offers a Printing Model—the Construction Master Pro DT
Printer! It has all the features of the Construction Master Pro Desktop,
plus a built-in printer (see Appendix C).
IMPORTANT: The Construction Master Pro calculators share many
keys and functions. However, some keys and functions differ. Please
refer to the grid on page 8to see what features are applicable to your
model, so that you can follow the corresponding examples in this
User’s Guide. Note: the Desktop with Printer (#44065) operates almost
identically to the Desktop (#44060).

INTRODUCTION
The Construction Master Pro line includes the most advanced feet-
inch-fraction calculators designed specifically for building pro’s!
The Pro calculators handle practically any problem involving measure-
ments and can be used to save time, prevent errors, and accurately
perform common building projects such as: estimating concrete vol-
ume, squaring up foundations, framing roofs, ordering lumber, building
stairs, walls, laying driveways, carpet or floor covering, figuring precise
angle calculations, or simply working in feet-inch-fractions or decimal
feet!
Your Calculator Helps You Solve:
•Dimensional Math Problems
•Conversions Between Feet-Inch-Fractions, Decimal Feet, Deci-
mal Inch and Yards
•English/Metric Conversions
•Problems Involving All Common Fractions –1/2" to 1/64"!
•Area/Volume Calculations
•Board Feet/Lumber Calculations
•Circle Calculations
•Material Estimations and Costs
•Rake Walls
•Right Angle/Triangle Solutions
•Stair Layout (Risers/Treads)
•Weight/Volume Conversions
Selected Models Also Solve:
•Block/Brick, Concrete Footing, Column and Roof Bundle
Material Estimation
•Complete Rafter Solutions (Regular and Irregular Hip/Valley Raf-
ters, Jack Rafters and Cut Angles)
•Trigonometry Calculations

KEY/FUNCTION COMPARISON
The Construction Master Pro calculators vary slightly in keys and func-
tions, sharing basic measurement unit, right triangle and stair keys.
Some models additionally compute advanced roof framing problems,
project material estimations, or advanced Trigonometry applications.
Note: The DT (Desktop) with Printer (#44065) operates almost identi-
cally to the DT (#44060).
