If you build or design things you know the importance of working with accurate dimensions. The most frustrating and costly construction headaches can usually be traced to dimensional errors. The Sonin DT110 InchMate+ Construction Calculator is for people who work with dimensions. The simple measurements (Foot - Inch - Fraction, or fif) you make with rulers or tape measures become difficult and tedious when you try to add and subtract them, let alone multiply and divide. The InchMate+ calculates these dimensions automatically. It was designed to be incredibly easy to use. It has a patented "self-prompting" system leading through the process of entering fif dimensions, and accepts inputs of to 1/16" - the practical limit of accuracy for common building and design projects.
This unique foot/inch/fraction calculator will automatically solve rise, run diagonal, and slope of any triangle. These powerful triangle functions make this calculator a must for anyone dealing with roof rafters, foundation layout, and squaring up angles, walls, and floor plans. It converts easily between feet, inches, and fractions; inches and fractions; decimal feet; and meters. It has a handy auto-off feature and comes with a long-lasting lithium battery and instruction manual. One-year limited warranty.
Sonin doesn't make these anymore--they stopped about 4 years ago. Any new ones that you purchase might not work, as ours didn't. Read morePublished 20 months ago by El-Nor

The digital display was all messed up. unable to read the numbers.
Great..need to design a steel fabrication calculator with chords and cambers. would have got more stars except no thirty seconds.Published 24 months ago by George Taylor
Ive had an 'inch mate' calulator for many years, loved it for its ability to do fractions.
Finally wore it out and needed a replacement. Read more
