Last question... (tonight)... How close does the Sonde have to be to what the receiver is?
I have an existing Ditch Witch 150R receiver which says it works with 30kHz sondes. I am thinking about buying the Metrotech vScan which says it works with 32.768kHz sondes. Would those most likely work with the Lecia Mini Sonde 33 which is 33kHz? https://shop.leica-geosystems.com/buy/accessories/mini-sonde-33 On Wed, Dec 28, 2022 at 3:53 PM Carl Peterson <cpeter...@portnetworks.com> wrote: > Speaking of Sondes...
