We actually had snow on May 1st, and hadn't seen the sun two days prior, so I was more than ready to get back to old, freshly moistened ground! So yesterday I got back to the deep coin park and tried a different program in the hopes of ignoring smaller aluminum targets while still getting good depth on coin-sized targets.
While it was cold and nasty outside, I played around with a new program called "GOODJUJU". Basically, it's the same program I ran all April but backed off on Sens and added a little more filtering.
4Khz
Sens 75
Disc 1
Full Tones
Audio Response 2
Overload 1
Reactivity 2
Silencer 2
Notch 00-24, 97-99
Manual GB = 88
Ground Notch 86-89
My goal was to get the same depth (within a 1" air test difference) for older US coins but to also reduce the sensitivity to deep pull tabs, beavertails, ring pulls, etc. With air testing I can hit a silver dime at 10-11" with this program, and with the previous program it was a solid 11" hit.
Came from these settings:
4Khz
Sens 85
Disc 1
Full Tones
Audio Response 4
Overload 1
Reactivity 2
Silencer 0
Notch 00-20, 97-99
Manual GB = 85
Ground Notch 86-89
After a few minutes of testing and tweaking, I found this newer Goodjuju program to be measurably less sensitive to a folded beavertail, by about 1". Couldn't see much difference in sensitivity to a silver dime, which was exactly what I was after....saved the program and then headed out....
First coin target sounded just like aluminum, there were no redeeming audio qualities to this specific target - so to my delight I pull a 1902 V nickel from about 6". 4kHz isn't as good on nickels as ALL of the other frequencies, but last year I did manage two V nickels from 10" down which I thought was purty darn good
Didn't come across a single Indian cent yesterday, but did manage to pull 12 older Wheats from 7-8" deep; some were mixed with nails, one had some foil in the same hole, and another had a transit token next to it at the 8" level.
Found a couple of shallow stud earrings at about 3" deep - so don't think that 4Khz won't find that small stuff. It definitely will, if it's shallow enough. These aren't silver, but I was surprised at the sensitivity to these items, even with Sens = 75
The audio in this program was smoother, more precise if you will. Small shallower aluminum liked to crackle a bit, although out of default I still dug it Got over a sweet high tone that registered 90-93 VDI and I knew it HAD to be silver...at 7" down out came a 1905 Barber dime. Deep coins were generally higher-pitched (no surprise there), but had a little something extra - I still can't put my finger on it or else I'd dig nothing but coins LOL. Iron targets were for the most part silent - I saw no change in how iron acted, but remember digging a couple of 9" square nails with no accompanying coin!
At one point I got a faint "blip" of a target and switched to a wide-open 8Khz program (Zero Disc, Zero notch, Reactivity 2, Silencer -1, Full Tones, TX=3, Manual GB = 85, Notch Ground 86-89) - I use this to check deep coin targets and listen for the audio to increase in pitch. In 8khz I got a much stronger, confident signal in the "nickel" range for 8Khz (ID Norm always off). At 7-8" deep I pull a beavertail, which was good since I demonstrated to myself that the GOODJUJU was working better at IDing those deep aluminum critters....4Khz was just a "blip" and the audio was cut and abrupt, not smooth and squeaky for a coin at that depth.
Initially I thought that aluminum registering "too high" was the result of too negative of a GB setting, so I upped it to Manual 88. Adding silencer helps with very deep fringe aluminum sounding "good" - the extra silencer I think helps here. Or maybe it's a combo of the GB, silencer, and Sens....I will need several more hunts in the exact same settings to say for sure.
