is it worth buying an hp 48gx or 50g in this 2023?

Greetings,
If you are into surveying software, I would recommend Jacob Wall's excellent program Cogo+ Pro. Recently I was looking for updates and noticed that is free of charge now, some years ago it was something like $275 USD. A 50G cannot run a survey instrument, however with Cogo+ Pro you can do comps that you used to do on a TDS48 but you are able save your points as ASCII or DXF or KML or Lat/Long files, store them on a 1 or 2 GB Secure Digital card that the 50G accepts, pull out said SD card and transfer back and forth with a computer. If you do coordinate comps and have a 50G...why not?
check out Simple Geospatial Solutions at https://sgss.ca/index.html and scroll down to 50G software. If you want his software for the HP Prime, that you pay for.

HP 45, HP 67, HP 41's C, CV & CX, HP 42s, HP48SX, HP48GX, HP 50G, HP Prime, I am a big fan of Thomas Okken's Free42 loaded on a smartphone & then punching in my old 42 survey software from the late 80's and early 90's. Much of which is available on hpcalc.org (RIP Ted & Thanks still!) Being able to do things like grade intersections quickly on your phone can be handy.
