ID NORM on vs. ID NORM off

[Tony N (Michigan)]

I just now tested three different coins; a silver quarter, silver dime and wheatback penny using 4,8,12,18 kHz..

With ID NORM on with each different kHz setting the numbers remained the same for each respective coin, i.e., Quarter = 95, dime = 93, penny =88.
With ID NORM off with each different kHz setting the numbers were different for each coin for each different kHz setting.

ID NORM off:
18kHz
Quarter 96-97
dime 93-94
penny 88

12kHz
Quarter 94
dime 90
penny85

8kHz
Quarter 90
dime 86
panny 80

4kHz
Quarter 85
dime 77
penny 67

So, why would you detect with ID NORM off?

Great info. Thanks for posting.

For checking bottle caps or steel
From low frequency to high frequency

Test a rusty bottle cap in each frequency with ID Norm off. It will stay the same if not increase with the lower frequency.

Nice work Tony.

Put it in full tones and check the sounds for each coin at different frequencies.

Its really what you're comfortable with. I run with it on but I run in 18kz. mainly. You can read caps just as well but the reaction is different. e.g a rusty steel cap in 4 will be knocked to the big iron range e.g. 98. In really trashy areas I've pulled coins by running in 4 and looking for vdi's below this range. I can see though why some folks prefer it off. If you run in say 8 or 12 the separation between trash and treasure is much greater. If I was going to ring hunt where slaw was a problem, I would run in 18 with it off then test a hit which will more easily tell you thats what you have. Bottom line your ears and your brain is a better discriminator than that screen.

Good point. But if I was in a place where bottle caps or steel were either very few or non-existent, I'd go with ID NORM on.

I wished I would have learned my machine with it on , it would have made my relic hunting easier instead of the numbers changing when I change kh and having to learn the numbers for certain items in each kh setting made the job 2x as hard imo.

I very rarely am out of 8 kHz except for an occasional iron check of a target at 4 kHz. I value the iron check and it doesn't work if ID norm is ON. If I am almost always in 8 kHz then my TIDs remain the same. I don't want them piled up at the top. The separation of the target TIDs is a help. To be honest I don't make dig or not decisions based on TIDs and nether should you. I do look at the numbers but it's for fun like guessing what will be there. My decisions for digging are based on the site I'm on, the depth and size of the target and the sound. If you make your decisions based on TIDs you will walk away from good targets. Targets in the ground are often adjacent to trash or are on angle which changes the TID. TIDs are no way to detect. Use your head and your ears, you will with practice be much better off and you will find more. Trash is just part of the game.
