hi
i am a surveyor, in china at the moment. i am going to get some dedicated programs written and i was told it would be better on the hp 33 as they are newer than my old 48 gx with cogo.
has the display comma been enlarged, does anyone know a good u.s.online source which has the newer version or a shop in frisco where a friend of mine can buy one and mail it to me
i see they are as low as 49 bucks.in australia they are about 150 u.s.d.which is a waste if i dont like it
should i look for serial nos above a certain number to clarify this
cheers
david

The HP-33S may be newer, but that doesn't mean that it is better than the HP-48GX. They aren't addressed at the same set of problems. The HP-33S is a programmable scientific calculator with a programming model that is similar to that of pre-RPL HP calculators. The HP-48GX is a graphing calculator with more memory and a much more sophisticated programming model. Which is better is determined by your needs and personal preferences. You can get the HP-33S from Amazon or Walmart. I bought one recently at my local Walmart store. It had the improved LCD display. I still don't like the legibility of the key labels, the shiny metallic finish isn't helpful. For $50, I can live with its defects. It's small, supports RPN, and is programmable. Its keyboard works reliably, unlike my HP-49G+, which was replaced under warranty and still doesn't work properly. If they ever get the hardware problems corrected, you may be better off with the HP-49G+ with its support for removable flash memory cards. That way, you can offload and backup data to a computer with a flash memory card reader.

David, I too am a surveyor in Maryland. I have an HP48GX with a COGO card installed and I also have an HP33S with some COGO programs that I wrote installed in it. Not to "pat myself on the back", but just so that you know my programs are not trivial, a college in Texas is using them in their curriculum. So I can tell you from experience, if you have an HP48, you don't need nor will you be impressed with the HP33S for field work. The only reason I can think of to use the 33S is for the NCEES exam as it is allowed and the HP48 is not.

Agreed. The 33S is a great calculator for solving problems on surveyor's licensing exams (e.g. LSIT/FS, PLS/PS exams), since NCEES has banned all other programmable calculators from such exams. But it cannot be used as a field data collector like the HP48GX traditionally was. The 33S only has about 32 variable memories, and no way to download data. A current 48 or 49 series model, or an older 48GX, would be a better choice. If you are interested in 33S surveying software for exams, there are some inexpensive commercial options, like this one.

You could wait a few months instead. This runs circles around the recon, ranger, allegro, and everything else out there. www.pssllc.com TW 12345 |
