Last hunt I went back to the faithful fairgrounds and was considering tweaking the 4 kHz program I run most of the time. I remembered someone asked me why used Notch and Disc from 00-02, rather than just either/or. This thought went round and round in my head all day long Saturday, and when I finally got out to hunt I decided to see what difference it made, if any, while hunting this location. Well, turns out that just a simple notch adjustment allowed for more crisp signals, and seemingly more sensitive AND quiet operation at the same time.
These were my settings:
4khz (Tx = 3)
Full tones
Sens 85
Reactivity 3
Silencer 0
Audio Response 5
Overload 2
Disc 2.0
Notch 02-30, 91-99
GB Manual "85
GB notch 85-90
Before, my goto 4 kHz program was identical EXCEPT Disc = 5 and Notch = 00-30, 92-99. I should have put two and two together when I lowered Disc from 20 to 5.0, and noticed the machine ran a tad more sensitive, but still remained quite stable; while good high-conducting targets had an extra "sweet sound" to the audio. Was finding a few bottlecaps that rang in 91-92, and decided to just blank out 92, making upper notch 91-99 to handle some iron targets.
But I wonder if the upper notch settings were making me pass up some fringe-depth coins? This is almost certainly the case for some coins, but that's why we are all here - to learn as much as we can with this exceptional machine! I've been considering eliminating the upper notch completely, and using my ear ENTIRELY at this site. I would never run out of stuff to dig, both trash and coins, since it's 36 acres of city property. I know that deep nickels will struggle to give a consistent VDI while in 4 kHz, and many times those deep nickels can hit in the 50s and 60s (whereas most non-wartime nickels register 36-39 in 4 kHz while in VDI range).
Another interesting thing I noticed during the hunt was the abundance of "00" and "02" targets that had a pleasant HIGH TONE AUDIO associated with them! Naturally I had to dig those up, and found that a few were coins co-located with mostly nails and bolts. A couple other "nice-sounding" targets were deep nails with no non-ferrous component at all. I remember digging 7" the other night to find a nail oriented vertically, which used to throw my CZ-6 for a loop. So right there tells me that the VDI is really not all the accurate esp. in the trashiest areas, which was no surprise but seemed to "click" for me once I tried Discing 00-02, rather than Notch AND Disc 00-02
I realize that many targets get overlooked that sound iffy, by almost all detectorists at some point or another, but the more I learn about Deus, the more it seems to be able to sort through the chaff. The star of last hunt was this neat Three Flowers compact from the 1940s-1950s made of brass. I got a "72-73" signal and it sounded deep. VDI locked on and hardly moved, and I was initially disappointed when I saw the compact thinking it was a 3-liter soda screwcap at 9" down.The hinge pin is brass as well, and the compact is still in great working order! It's nice to NOT dig 9" and spend 10 minutes, and get a stinking piece of crap...I also found a half-dollar sized aluminum blank at 8" depth last hunt - the signal sounded sweet, VDI locked on at 76, and thought a silver dime was in my future!!!
Next hunt I will leave the program as it is now, and concentrate on the same area where I found the old compact - this is probably the hardest-hit area of the fairgrounds, but has been spared the wrath of bulldozers at least since the 1920s...
