(included)\n\n- BUILT FOR THE JOBSITE, NOT THE CLASSROOM — 200+ construction-specific functions including feet-inch-fraction math, rafter calculations (rise, run, pitch, diagonal), stair layout, concrete\/material estimation, and area\/volume with built-in waste factors. Replaces your Construction Master Pro at half the price.\n- FULL LAYOUT MATH, NOT JUST MATERIAL COUNTS — goes beyond how-much-to-buy estimating: hip and valley rafters, compound miter angles, roof pitch and angle conversions, stair rise-and-run layout, polygon tiling, and foundation correction. The math a framer, roofer, or finish carpenter actually runs every day.\n- LARGE 3-INCH, 12-DIGIT DISPLAY + BACKSPACE KEY — a screen you can actually read at arm's length in daylight, 45 glove-friendly hard buttons, and a backspace key so one typo doesn't erase the whole entry — a feature the big brands still haven't figured out. Drop-proof TPU shell shrugs off jobsite drops, dust, and spills.\n- BUILT-IN LCD WRITING TABLET — flip-page notepad right on the calculator. Jot measurements, sketch layouts, or write cut lists without hunting for scrap paper. One-touch clear wipes the page for the next number, and the erase-lock switch makes sure a bumped button never deletes a cut list mid-job.\n- EASY TO START, DEEP WHEN YOU NEED IT — battery included and pre-installed, and the 2 quick-reference cards get you running the everyday functions in minutes; grow into all 200+ as the job demands. Auto-off after 13 minutes saves power. The tool they didn't know they needed — a perfect gift for contractors, carpenters, electricians, and DIYers.","brand":"My Store","offers":[{"title":"Default Title","offer_id":60039914062110,"sku":"P359356084114299720","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1094\/1425\/2830\/files\/71YVGO-kooL.jpg?v=1790237405","url":"https:\/\/uiuihjkx.shop\/products\/construction-calculator-with-writing-tablet-feet-inch-fraction-carpenter-calculator-for-framing-roofing-concrete-material-estimator-200-functions-gifts-for-contractors-b0gy9j3xn1","provider":"My Store","version":"1.0","type":"link"}
