I realise it's what you're used to, but I could never get the grips of a landscape calculator.
It just didn't fit in the hand like the 41.
That also influenced me even in the Android version.
Is there an Android one that once programmed you can actually backup or save.
I programmed my 41 only for it to reinvent itself one morning and lose the lot. Very kind of it!

I spent as much time checking against trig tables as I did using it. Couldn't grasp that it could figure them things out without a book. 😉

Don't know about the program save aspect but this is free and might be worth a try.

The HP 12C is the financial version of the11C. It was the standard for real financial analysts when I did that sort of work. Folks who used anything else were suspect as to ability and insight.
[USER=379]@FL/GA PLS.[/USER] Yes that's the one I use and like very much.
It's also the one that spat the dummy once after I'd programmed it.

That is the basic app
There is the go41cx

and the pro version go41cxt

that will get you what you are looking for.

We use to say the same about engineers that used Texas instrument (TI) calculators apposed to HP. 🙂 Jp

Speaking of TI's.... when I was taking a PLS exam (don't remember which state), I took a HP-41CX w/Survey Pac as my primary and a TI-60 for a backup. As the proctor was making his rounds before the exam begin, he stopped and looked at the TI, then checked his list, then told me to put it away because it wasn't on the approved calculator list..... but let me use the 41.....:cool:
To answer the original post, I have an 11, rarely use it. Also have a 45, several 41's and 48's, and others I can't remember off hand.....
I can explain it to you, but I can't understand it for you...

I have had the HP 12C paid android version on my phone for several years. It works perfectly. I love it, especially when purchasing a new vehicle. Or bonds, PV, FV yada, yada...:cool:

It's a pretty good guide, I'm sure. I haven't kept up, but I believe that the serious engineering professors at NC State use HP. On the other hand, my engineer son got his ME degree at UNC Charlotte where the standard was TI. He used a TI 86 (old Z80 processor) and, I think, he is a pretty good engineer. The HP50g may have made him a better one, though.

My goof. Didn't take enough notice. This is the one I have.
I had both, one on phone and one on tablet.
I'll reenter my program and hope for the best.

[USER=833]@Richard[/USER]
they made some recent upgrades on those two apps and if you have the cogo download and overlay data file (that I can't find now) you can load that into the app.
[USER=81]@A Harris[/USER]
Thanks. I'll look into that.
My issue was on my previous device.
The 15C has got to be the best calculator ever. I got mine from my boss at my first survey job in '78.
It's in my car, on my coffee table, or shirt pocket. Use it daily. And, I still program it as needed. It's near perfect. My 41Cs are stacked away, they're precious too.
I have the iPhone 15C app, 41C app too.
Fortunately there is a 15C remake, Swiss Made DM15, and DM41. I think the 15C rocks even by today's standards. The 11C was good, but it's like a 4 cylinder versus 8 cylinder compared to the 15C.
At my test time ('91) there were architects, electricians, whatever, and land surveyors, in one arena. Architects had Casio, TI, Sharp, and others. But all of the land surveyors had HPs - 41C, and often 2 or 3 if them. I prepped for the test by programming my 41Cs for SPC (NAD83, and NAD27), astronomy,and cogo. Can't imagine any other line of calculators that will ever be as good as the HP10 series.

I thought architects pretty much stuck with Fisher-Price.
I bought an original HP 35 in 1972 while in college, ($375 I think). I used it for the PE exam in 1982. A few years later I bought my dad an HP 25 (about $250). I bought an HP 11 ($110?) and an HP 41 with Survey Pac and a printer in 1986. The HP 41CX sits on my desk with dead batteries. I was sure I bought a new set but cannot recall where I put them. I will give myswlf some more time to find them before buying another set. The shortest time batteries ever went in the 11 or 41 was at least 5 years.
When it became difficult to find the rechargeable battery pack for the HP 35, I tore one battery pack apart and ran it with 3 regular AA batteries for years. Now it just sits on my desk without batteries and I run it off the charger. When my dad's HP 25 died I bought him an HP 11 ($50). I got that back when he died. I used the HP 11 for the FS and PLS in 2001. I bought my first of several HP 48s in 2002. One HP 11 got misplaced or walked away in another engineering office a few years ago. My son bought the new HP 35 version to prepare for the PE exam, but did not care for RPN. After he passed the exam it came my way.
About a year ago my HP 11 hit the floor and cracked the screen. I was shocked at what used ones still go for on eBay. I went cheap and bought a used HP 12 for $12, disassembled both and used the 12 screen in my 11.
By the way the HP 12 is still being made and sold and it is used by more than accountants and insurance agents. When I was in for radiation treatment for cancer I saw the nurses using HP 12s to accumulate radiation doses just like it was compound interest. New price is still in the $50 range.

They obviously didn't function too well.
Artichokes house plans dimensions still don't add up correctly, and if you notify them about it they become pissed off even when you are correct. "Kill the Messenger" type attitude, or "How dare a lowly survey creature correct someone of my status". 😮

My distaste for architects was not derived from a flippant whim. Years ago I provided to an architect a topo and boundary of a very 'spensive lot in an exclusive golf course oriented development. I was asked by the contractor to stake the construction.
Long story short the architect had the lot represented as square and there was actually a degree and a half convergence on one side. Simply put the house would not fit on the lot. I explained this to the owner and the contractor. The architect eventually provided revised prints so the house would fit....and billed the owner for "additional work required because of a surveyor's error". The owner sent me the bill. We all eventually sat down in my attorney's office and hammered thing out...but the architect himself was not present, he sent some bozo in his place.
After the meeting I told the bozo to tell his boss "if I ever meet him on the site he will definitely remember it". And I meant it. That was the only time in my professional career I weighed the legal repercussions of whippin' someone's ass against the personal satisfaction I would receive by commiting the offense. A scary place to be....
Along with the 11c and 12c calculators, HP also made a 16c. Designed for computer programmers, it was discontinued in 1989. Many of its functions are now available on much cheaper scientific calculators.
Programming errors on mainframes back in the eighties often caused massive core dumps of hexadecimal numbers printed on stacks of green screen paper. A programmer on call would get out of bed at maybe 2 AM, drive to work, and pour over the dump and code for as long as it took to fix the problem.
I had both great respect and sympathy for those folks. Working in corporate, I had a bit more budgetary freedom (less accountability) than line managers had, so an HP 16c showed up on a central desk in IT with a note that said something like "for hard to clean dumps."
It, like most of us who labored in those times, is probably long gone from that workplace.
