I ordered a smaller metrotech D18 33kHz sonde and a vSCAN locator which says it supports 512 sondes (*- Sondes: 32.768kHz, 512Hz and 640Hz Sonde modes). *I'll update with how it works with the D18 and the sewer sondes. If we end up buying a longer sonde I'll do a side by side with them.
Thanks for everyone's input on this. I'm sure I will wish I bought a RD7200 at some point but hopefully this will get the job done.
