Calculated Industries Construction Master Pro

The construction master pro 4065 from Calculated Industries sets the industry standard for advanced construction math calculator. Offering powerful built-in solutions and expanded preference settings, it's perfect for completing layouts, bids, and estimates as well as helping to save time and money by helping you figure out the right amount of needed materials. It's ideal for or contractors, estimators, architects, builders, framers, engineers, concrete/foundation contractors, draftspersons, and more.

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 time-saving 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; 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.

Handheld Convenience

The construction master pro also includes the 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 two 1.5-volt batteries (LR-44/A76), 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.

I am using the calculator for both work and school. For work it has saved me so much time but in school we need more soft conversion than hard conversion(ex. inches to cm, or yards to metres). It would be nice if you had a calculator with this ability!

I was all set to love this calculator until I discovered it doesn't calculate rafter tail length. Then I found that the 4067 model does calculate total rafter length including the rafter tail. I returned this item and intend to purchase the 4067 model in the near future. Excepting for not calculating total rafter length, this calculator is very, very helpful.

This is a great construction math calculator. I have used them for the last 15 years and would not be without one. I ordered this product and it was delivered the next day I was amazed. Great company!

Be advised an armadillo case came in the box with my order of this product, you might want to wait before ordering the highly recommended armadillo case separately as you too might get a "bonus" package with a case. You also get a $10 off coupon for two licenses of the PC version of the calculator, nice to have since the PC version can do the extra trig functions that are not part of the 4065 calculator.

I had recently married a man in the construction business. I was lost when it came to measurements. I had no experience in this profession. Now, i can easily figure pitch, width, height, etc. The dvd that came with the calculator showed me exactly how to input the data and come up with the correct answer, it was so easy to understand and powerful construction calculator!

What a great addition for my Handyman business. I am amazed at how efficient I can be with this calculating tool. Formulas I use daily on the job is solved with some strokes of the keys. No more figuring on pieces of paper or pieces of scrap lumber. If you are handy around the house or run a home repair business, better add one to your tool box. You will surely not regret it.

If you do any work with construction like cement pads, carpentry, even conversions, get this little jewel for the farm or work shop. I played with it for days then used it to order concrete for a new barn pad which I squared up with it first. Waste of concrete was negligible. Also used it for truss lengths in the barn repair. I do recommend sitting down with it, reading the manual and running through the examples to really learn the power it has.

I've held out on buying a construction calculator for the longest time. Finally thought I better buy one for some more complicated calculations for a sloped site project having to go between civil elevations in feet and my own architectural drawings in feet and inches. It's been so much easier using this little guy as opposed to my iPhone calculator or even trying some of the apps.

This is my third calculator from Calculated Industries and the product keeps getting better over time. The amount of time this saves me both in the office and on the jobsite is worth its weight in gold. If Calculated Industries keeps developing and improving their product line, I will keep upgrading as we continue to grow.
