Review: Very useful in framing works. Review: Un mio collega possiede il modello precedente di questa calcolatrice e, dopo aver provato la sua ed averne constatato l'enorme utilità, mi sono decisa ad aquistarla a mia volta. Il prezzo è forse un po' alto, ma la facilità con cui ora riesco a gestire conversioni, somme e computi metrici per offerte è impagabile. Inoltre, guardando il libretto di istruzioni, sto scoprendo tutta una serie di funzioni che costituiscono certamente un valore aggiunto. La confezione, al posto del guscio di plastica standard, includeva un bonus, ovvero la custodia protettiva "armadillo gear". Questo accessorio temo che in realtà abbia notevolmente influito sul prezzo di vendita - la stessa calcolatrice, infatti, se acquistata in un negozio fisico negli US ha un costo di gran lunga inferiore. Ma io non volevo aspettare di andare ad acquistarla direttamente e comunque l'idea di una cover protettiva mi sembrava un'ottima cosa per proteggere la calcolatriche da danni da caduta quando sono fuori ufficio. E questa copertura in gomma effettivamente protegge la calcolatrice da qualunque tipo di urto, peccato però che ne aumenti l'ingombro in maniera quasi eccessiva, rendendo impossibile di fatto il trasporto in tasca. Inoltre, la custodia è larga e raccoglie quindi ogni tipo di residuo e polvere; il gancio dello sportello, infine, rende difficile poterlo aprire e si deve sempre operare con due mani. Quindi, questo mi impedisce di utilizzarla per lo scopo per cui è stata acquistata - ovvero una gestione facilitata anche durante le fasi di lavorazione. Dato il costo, ho ovviamente cercato di acquistare la cover standard separatamente (ora devo rimuovere lo scudo protettivo quando sono in posti senza piani di appoggio confortevoli) per avere una protezione seppur minima proprio nelle occasioni che contano, ma senza fortuna. Non posso quindi dirmi completamente soddisfatta. L'oggetto in sé è ottimo con perfette funzionalità ed un funzionamente intuitivo, ma l'imposisiblità di fruirne come pianificato ne diminuisce l'utilità. ## Features - Imported - Parallel import goods - Sold in the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007Q3RGQ | | Amazon Bestseller | #211,195 in Office Products ( See Top 100 in Office Products ) #88 in Scientific Calculators | | Are Batteries Included | Yes | | Brand | Calculated Industries | | Customer Reviews | 4.8 4.8 out of 5 stars (4,655) | | Date First Available | August 8, 2012 | | Item Weight | 231 g | | Material | Plastic | | Model Number | 4065 | | Model Year | 2014 | | Power Source | Battery Powered | | Product Dimensions | 14.61 x 7.62 x 1.52 cm; 231.33 g | | Voltage | 1.5 Volts | ## Product Details - **Brand:** Calculated Industries - **Calculator Type:** Engineering/Scientific - **Number of Batteries:** 2 LR44 batteries required.

Is this a good tool for a roofer?** A: I got this for my husband and he tells me every time he uses it how much he loves it. It does everything that he needs. One of the best gifts ever. I use it a lot myself, so hope he will get me one soon. **Q: I have a older version...maybe 5 yrs? Is this one more advanced?** A: Thanks for your question. There have been no significant changes to the Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator in the last 5 years other than the addition of the Armadillo Gear as standard. If you have one that is no longer working, you can send it in for repair. **Q: Does the CI 4065 pro delivered have an orange back or black back?** A: the calculator it's self has a black back, i got mine with the armadillo gear cover and the main body including the back is orange but the flip cover face is a dark graykevin **Q: Will it tell me the amount of concrete i need for a slab?** A: Thanks for your question. The Calculated Industries Construction Master Pro Calculator will calculate cubic yards using the Length Width and Height keys. This is a great all around Construction Calculator, however if you are dealing primarily in concrete you might want to check out the Calculated Industries ConcreteCalc Pro as it has advanced rebar and column functionality.

If you work in construction it would make your life easier. It takes some getting used to the range of functions however if you are a joiner the stair function and traditional cut roof functions are great. You can input metric or imperial although the inputs are more logical when done in imperial and use the American phrases for roofing and framing. It has a good instruction booklet however the you tube channel is the best resource. The quality seems to be very good but came with a tough case too. Well worth the money. ## Frequently Bought Together - Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator for Contractors, Estimators, Builders, Framers, Remodelers, Renovators and Carpenters - Aproca Hard Storage Travel Case, for Calculated Industries 4065 4080 Construction Master Pro Calculator (Case Only) - Calculated Industries 2140 Construction Master Pro Workbook and Study Guide | 4 Comprehensive Sections | Site Development | Footings, Slabs, Walls | Framing | Finishing |Practice Problems, Answers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/725853347-construction-master-pro-project-calculator](https://www.desertcart.sc/products/725853347-construction-master-pro-project-calculator) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-05-02*
