Complete trigonometric functions in a handheld field calculator ().
A more compact version of its desktop sibling, the handheld Construction Master Pro Trigonometric calculator (model 4080) from Calculated Industries is the most complete construction-math calculator on the market. 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, architects, builders, engineers, project managers, estimators, 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. 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.
Handheld Convenience
The Construction Master Pro Trig 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. The 11-digit display measures 2.5 x 0.625 inches. Overall, the calculator measures 5.6 x 3.0 x 0.6 inches, weighs 4.5 ounces. It's backed by a one-year limited warranty.

I like the ability to have the conversion chart in the underside of the lid and the handy storage case. I live in a damp climate and proper protective cases for electronics is a must. Also I was able to place the instructions manual under the calculator inside the case.

By trade, I am a structural and miscellaneous steel draftsman. When I started in this line of work, there was a limited amount of calculators to choose from, and most of them required the user to work in decimal form only. Then, I found the feet-inch calculator from Calculated industries. It changed everything for the better. The biggest advantage was that it cut down on the human error. There are times where I will have a string of dimensions to add or subtract. One of the features which aids in this is the "paperless tape". It will keep a running log of the current function the user is performing much like the old adding machine tape. The calculator only got better as time went on. The addition of the trig functions was a huge bonus. Probably the only con I have is it has a limited amount of memory storage. It only has three storable memories, and sometimes, I could really use five or six depending on the formula I have to run.Overall, I am a very satisfied customer...

When I ordered this unit I didn't realize it was intended for bridge and skyscraper builders! After I got it and tried to use it for the first time I had to stop my project and go online to learn to use it properly for what I needed to do. That took a couple of head scratching hours but finally I got it. Not the fault of the calculator though, thus the 5 stars overall. There is a more basic unit that would have been just fine for my needs (building a two story workshop) and I didn't realize it. This is the TRIGONOMETRY version and like I said if you are planning on building the Golden Gate Bridge or Taj Mahol buy away. Otherwise maybe look for the simpler unit. It did help a lot with the stair risers, rafters, and trusses though but I guess in most areas they won't let you build your own trusses anymore.

Product is great, but the workbook should be bundled with the 4065 calc rather than the 4080. I was disappointed to find a good portion of the workbook undoable because the 4080 replaces the Length, Width, and Height buttons with the Trig (sin, cos, tan) buttons. The bundle really needs to be changed. I had to order the 4065 and now have to return this 4080.

Being able to work in either fractions or decimals is a real plus. This calculator is packed with useful functions to include trigonometric functions. Worth the money to me.

I have had various Construction Masters over the years. Some have been lost/misplaced and a few older models buttons have worn. Great for adding/subtracting/multiplying/etc. feet and inches. Easy metric conversions. Calculates, run, rise, pitch. Trig functions. Booklet is filled with formulas to help you with any special calculations and can fit conveniently between your calculator and case.The protective case has a flip-hinged lid with a quick reference guide printed on it. The bright color of the case helps locate it quickly/easily. Case fits snuggly, but can come off easily if/when you need to take out the calculator.Received in a timely manner, professional transaction.

This has to be my fifth or sixth Calculated Industries calculator purchase. I have two at my work, two at home, I keep one in my car too. I'm glad that my 4080 Pro came with the rubber armor as this should help with using it in the field and getting dropped.If you want a calculator to do the work of figuring feet and inches, cubic feet, square feet, stair layout, rafter pitch, volumes, board feet, material quantities, ounces, pounds, converting cooking measurements, figuring mortgage rates, time cards, payroll related calculations, handheld machining math, thread data, drill size chart look-ups, speeds and feeds, right triangle solutions, bolt patterns, estimating, takeoffs ...... the list goes on and on and on and on......If you need a calculator to help with the items mentioned above than look no further than Calculated Industries.I work in a structural engineering office and this is my second 4080 Pro. I love the fact that it has "Trig" functions as well as the basic feet and inch functions. That is about 1% of what this little machine can do. I starting drafting with a 'T' square and now working on Revit so I've seen a lot change in my career. I wish I had the 4080 Pro when I was a younger draftsmen. It is an indispensable tool in my electronic briefcase of gadgets.As long as Calculated Industries is in business and I have a need for their calculators, I will purchase no other brand.Good instructions, ease of use, good battery life.
