On the beaches here on Cape Cod my old trusty DFX was unable to auto ground balance but instead would initiate default factory settings. Scrolling through the many settings I always selected "ground tracking on" Hopefully, soon I'll have a Nox 800. as the DFX needs a new coil and/or some box work. Too old. Sorry DFX. Would using "tracking on" on the Nox provide better performance?
