    Thanks, Paul Quagge

  • CORPSCON - yes - used it.  
  • Gary,


    Have you tried CORPSCON? I have used it for years to do just that, you can convert a single point or multiple points either direction. I added a link to the tool box


    hope all is well my friend

  • You got batteries? I did and very happy to have some 3960mA 3.7V battery units that fit right into my PM3 for about half the cost of what others have quoted me. I worked hard to find a good deal and I took the risk and ordered two for about the cost of one from my regular supplier. Send me a buck and I will tell you my secret. PayPal me at - well worth it. Also I got a 3200mA battery to replace the whimpy 1300mA that came with a new cell phone. My cost was at least half of what I would pay at WalMart, LOL for anything close to as good. Now if I could at least find that touch screen part.
  • FANTASTIC!!! Thanks Phil - I found it on the PM3 and tried it. Works great. Now if I can find a spreadsheet to add to my collection to do the calculations for me, LOL.
  • The calculator that works in FAST Survey on the ProMark3 is described on page 62 of the ProMark3 RTK Reference Manual. It is on the COGO tab of the FAST Survey menu.
