I hate 88 .....

[martygene]

seems like the Deus really likes to find twist off bottle caps at 88.... same number as dimes... that is not fun... I couldn't find a way to get around that... if I notch out 88 then I don't find any dimes, especially silver ones... I was using the basic 1 program but I have virtually no ground mineralization around here so I had the sens cranked to 99 and the react at 1, disc at 10. I tried lowering the sens, and raising the disc to no avail. I did get a lot of older rusted bottle caps too at around 84, 85 so I stopped digging that number eventho pennies fall in that range but I couldn't stop digging those darn 88's...
I am a new user so I don't know the machine that well yet. the other day I found two silver dimes with it, one being 88 and the other at 91...
any ideas or suggestions as to not dig twist off bottle caps but still find good 88's would be much appreciated.
Thanks and HH & GL

I have found the aluminum screw caps to cause similar problems on a lot of different machines I have used . They seem to id like silver a lot of the time . About all I have done is not dig the more shallow 88 hoping to find deeper silver where the caps are very thick. That being said I have dug thousands of them over the years and figure it is just part of the game. Sites that are old and still have a lot of caps should still have some silver because cherry pickers are going to leave silver if they pass most screw caps in my opinion....

I've been using a 4 kHz program that pushes most steel bottlecaps to 89-91 range. Using 4 kHz will push silver dimes down to 74-80 in my soil, and you could have your basic 1 program in an adjacent slot to check targets. Upping the silencer settings past 2 will help "chop" a bottlecap signal and make it more recognizable without switching programs.

4 kHz by itself will ignore many caps, but if you get into a cluttered area, some signals like to "smear"..

I posted a program today that's based on Coop's bottlecap program that really helps me with the dig or no dig determination without changing anything on the fly.

"4kHz SUPER"

4 kHz
Sens = 85
Reactivity = 2
Full tones
Disc = 20
Silencer = 2 (goto 4 if caps are every few inches or so)...you will lose a little depth with higher reactivity/silencer settings
Audio response = 5
Overload = 1
Notch = 93-99
Ground balance = Tracking works well in clean soil, but I use manual at 83 ( my soil averages 80-85 most of the time)

If you like to set breakpoints using 4 kHz will give you more VDI spread on targets and will push bottlecaps to 89 and higher most of the time. A silver quarter will ID at 85-87, silver half dollar chimes in at 88-89, and a silver dollar hits 92-93 in this program.

How deep are you finding the silver? You can expect to hit a silver dime with the above settings comfortably at 8" with relatively clean soil, and up to10-11" in reactivity of 0 or 1 in the right conditions. But if caps are plentiful raise reactivity to 3, silencer to 1 or 2 and you can still get dimes at 7" easily...more with higher sensitivity!!! Good luck!

Yikes CZ... That sounds like a lot to remember....... But. I will set that program up and give it a try. Thanks. This machine is complex and difficult to learn for sure. I have Andy,s book and some of it makes sense and some isn't sinking in yet.

There are other programs that work pretty well, but steel bottlecaps are a problem with the Deus currently. I wonders why there are no 4 kHz programs in Andy's book, maybe there are and I just missed them...

I have the same bottle cap problem. Set myself up a 4 khz program next to my go to program and if I suspect a bottle cap, I switch to 4 and if the numbers jump into the 90's, I know it is a bottle cap. Works for me. I proved it to myself by digging.

 

[martygene]

Good to know and I'll give it a try. Thanks

Have you tried turning on the feature that sets all ID numbers to the 18 kHz frequency. That might help because the silver dimes usually ring in at 91-92 for me.
