They are different, the ML will not show so much info w/ the smartfind thingie.
While the White's signagraph will use bars which can "build up" or scatter etc all over the graph area, they can even build up "clusters" (aka multiple bars close to each other)
Also based on the height of the bar(s) the signal strength can be guessed.
The signagraph has also sections like the VDI the more to the left the greater chance it is that it is iron the more to the right the greater chance for it to be copper, silver. (high conductive metals)
Note that some hot rocks can mess with the detector/discrimination etc.
The ML smartfind will show ferrous content/properties(?) and conductivity.

The DFX can be a very powerful machine by just adjusting 4 controls. Pre amp, sensitivity, sweep speed and discriminator pattern. Round 2 improvements would be recovery rate, filters, bottle cap rejection and hot rock rejection. As a matter of fact, I highly recommend not tweaking all of the controls at first. Start with those 4 and add some in later. Always do an AIR TEST to confirm out of ground depth results. No offence to the MXT people, because it is a very good out of box machine, but there is a real reason why the DFX is White's top machine. It finds things deeper than any other White's machine in the most diverse conditions. It is harder to use if you want to get intricate with it, but it can be a very simple to run machine. If anyone is afraid of adjusting just 4 controls, then maybe the DFX would not be their best choice. But I know that some of my best finds were found under conditions that required the capabilities only found on the DFX, and I've found some pretty good finds over the last couple of years. Just my opinion though. HH
