With your experience and the CMPro you can build with confidence

Quick, accurate solutions in the field
You'll be able to work in and convert between all building dimensional formats--yards, feet-inch-fractions and metric--including area and volume.
The Construction Master Pro includes a number of built-in functions, including calculations for risers, treads, stringer length, and incline angle; how many 4 by 8, 4 by 9 or 4 by 12 sheets are needed to cover an area; jack rafter results for regular and irregular pitch roof; and right angles.

Handheld convenience
The Construction Master Pro also includes the ability to custom define your preferences, a 'paperless' tape that lets you review the previous 20 entries to double-check totals, and accumulating memory with three additional memory storage locations.
It has an auto shut-off feature that turns the calculator off after about 8 to 12 minutes of non-use.

Ready to use
This model comes with one Calculated Industries 4065 Construction Master Pro calculator. Plus it comes with an Armadillo Gear protective cover. Additionally, it has a pocket reference guide in English/Spanish. The two LR-44/A76 batteries are included so the calculator has everything you need to start using it.
Safety & Compliance
Designed with a tool-secured button-cell battery compartment to reduce risk of unintended access and align with current U.S. consumer product safety requirements.
