Does higher reactivity mean slower swing speed?

Slower swing speed with Reactivity at 3 or higher will allow the detector to separate targets better. If you get a blippy or chopped signal, slow down and rescan the area and let the machine "hook" the target. If it's a medium to high conducting target most of the time it takes a couple swings for the software to "resolve" the signal and the audio quality will improve. ON these types of signals ignore the VDI completely and dig by audio - chances are it's a coin mixed in with foil, nails, etc.
Went back to the most productive rental property last night and mowed the yard as part of our agreement "I will mow your yard once if you let me detect!" (most people can't pass this up and it's only a 60' X 45' yard)
After that I went up to the front steps area where I found the Walker and put Reactivity into 4 with silencer at 0 and proceeded at a snail's pace. Iron Vol was at 0 and I had Notch set at 00-27 to quiet the machine down somewhat with EMI, foil, etc in 12 kHz. Anything repeatable was dug, didn't look at the VDI in the 45 minutes that I hunted the area but managed to pull a dateless Buffalo nickel, two Wheats, a couple high-relief memorials (1959 through 1968 ), and a small brass tack at 3". At this reactivity setting you can still get US copper pennies at 6" deep, but that's about it as far as depth goes. The buffalo nickel and one Wheat had several roofing nails in the same hole as well as deeper-seated longer nails about 8-9" deep. It doens't matter for the most part the orientation of nails in the ground - as long as there is a coin or other high conductor present there will be an audio signal before the machine resolves the target for a dependable VDI.
A snail's pace for me in Reactivity 3 or 4 is about 12-18 inches per second. Keep the swing speed steady and be sure to sweep 90 degrees relative to your direction of travel on return hunts. You can get decent depth at Reactivity of 3 and a slow sweeping speed - maybe 7-8" max on a US small cent while quarters and halves max out around 10-11" (in my soil, GBs around 82-84)

Excellent info. Exactly what I was looking for. Thanks CZ! I find myself not even looking at the VDIs. I just keep the control box in my pocket in a dust free case and only pull it out for adjustments. Hunting by tones with limited disc and utilizing the notch seems to be quite productive for me. I feel like it keeps me from overlooking decent signals that I may decide not to dig if the VDI is low.
