I will try the 3 and 4 Reactivities. However, I do notice a big difference in decreased detection depth with the LF coils with Reactivity above 2. I just assumed the same applied for the HF. Good to know.

Got a little "catch and release" detecting in at an archeological site today as a warmup for later this week. Tried the GF program recommended by Andy S. against my normal minimum discrimination program on some medium hot soil and both ferrous and non-ferrous targets. This is bad soil but still not as bad as Culpeper. Perhaps 1/4 to 1/2 up the bargraph. Cut grass field.

This is not scientific as I was limited due to this being more of a work site with cataloging etc. so I do not (ironically, considering the cataloging taking place) have video or pics but was able to do a couple side-by side comparisons of the Deus programs.



"Discrimination Program" (Frequency as described below, Disc at -6.4, Sens at 90, Rx at 2 to 2.5, Silencer 0)
"Gold Field Program" (Frequency as described below, Iron Audio Reject (IAR) = 5, Sens 90, Rx (as described), Threshold barel audible)

Flat Button at 5": Disc Program - not audible at either 14 or 28 khz, GF Program - audible but no target ID, 28 khz was a little louder

Gardiner Bullet at 5": Disc Program - not audible at either 14 or 28 khz, GF Program - audible but no target ID, 28 khz was a little louder

Square Nail at 7": Disc Program -Definite Iron Grunt at either frequency, Target ID = 00 or no TID. GF Program - IAR definitely broke up the iron signal. Liking the IAR as a means to ID iron (except as noted below)

Thick, round (2.5" diameter, 1/2 inch "tall" and 1/4" "thick") iron ring - Disc Program - Rang up a sweet high 80's, Low 90's tone depending on frequency. GF - Also rang up with similar TID and though Iron, did not break up with IAR. So the deus still gets fooled by those perfectly circular ferrous targets.

So I am like the GF program. It gives me a target signal, though at decent depths, no target ID and the IAR does a pretty good job at telling me whether I am hitting on a ferrous or non-ferrous target.

I will tell you, though. This outing was a warmup to get my Minelab GPX ears tuned in for an upcoming 3-day hunt and there is no doubt that the GPX rules in this hot Virginia Soil both on depth and ability to ID targets by tonal quality. I will be testing the Deus at Culpeper but my primary machine will be the GPX. I am really optimistic about the IAR giving the Deus a respectable showing in Culpeper, however.

Been out messing with Reactivity 3 and 4 with the round HF coil and I must say the depth with Freq 14 and even 28 are impressive. However, the high conductor silver is tougher to capture. I also feel that the pitch mode gets a little deeper than both the multi-tones and the full tones at the same settings. I don't know if this is just the way I hear or if there is something different in the way the control module processes non ferrous in the pitch mode vs any other mode (excluding GF)?
