Coolest calculator ever for construction!!!!
Has all the features of the 4065 and the 4080 trig model.I also have the 4065 which is more portable.Not exactly portable but it’s awesome!!All of the construction master calculators are incredible.Also they have a huge library of videos on YouTube and if you get stuck you can call them and there’s always a person there that can help walk you through it.Great customer service. Every time I’ve had to call it’s a real person here in the US. Can’t say enough good things about this calculator and the company.

Good sturdy functional dimensional calculator
My old one finally wore out after maybe 20 years, so I bought a replacement that should last me until I retire in another 20. I like that the company is out of Nevada not far from where I used to live. I don’t use half the functions, but it’s nice that they are there. Strong case protects it well.

You cannot go wrong with this calculator. check into it you will be satisfied!
I think this was the best calculator on the market hands down! You also have an option of the app with Google Play and other platforms that works just as good and well I have both and I’ve had the app for years just ordered the handheld calculator and I am very very happy with it!

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 facilitàcon 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 realtàabbia 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 funzionalitàed un funzionamente intuitivo, ma l’imposisiblitàdi fruirne come pianificato ne diminuisce l’utilità.

it would s a high quality calculator that is easy to use, with the large buttons and display.does easy calculations for stairs, rafters etc,converts metric into feet and inches and back in one easy step.

I am really glad that I bought this and relieved that I could buy it in the UK. 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.
