So I have been going out at lunch time putting in the time with the V3i. I have learned lots of stuff. Just yesterday, I found where I could adjust the modulation of the sound in the V3i. First, though, I had to learn it is called Modulation LOL!. The factory default Coin and Jewelry (C&J) program gives you the same loud signal no matter how deep the signal is. I got used to hearing dim, soft signals on deep coins with the AT Pro so I set the V3i the same just today at lunch time.
By the way, every day I see why so many people don’t want to mess with this detector. Using the V3i is like suddenly being able to see in Infrared, Ultraviolet, and Visible light all at the same time! It takes a while to get used to it. However, that’s the power of this machine. Yet, the more I read the manual and the forums, the more I become aware that the number of settings is finite and actually quite manageable.
Also, I learned how to make the changes to the C&J program without screwing the machine up. So now I am seeing stuff down to thirteen plus inches consistently. Unfortunately, so far, it has been rusty nails and even a wine screw top at about eleven inches deep! How in the world did that get there??!! By the way, finding that wine screw top that deep gives me hope that I can find a quarter that deep as well.
So today I got an interesting dime signal. The threshold dropped every time I heard the dime signal, indicating that there was iron in the hole as well. So I dug up the “dime” which ended up being just an aluminum beer screw top. Out of curiosity, I decided to dig the iron signal as well, which was about one to two inches below the screw top. I dug up a rusty skeleton key.
My first note worthy find with the V3i!
Five inches deep. What did this key open?
Thank you for looking!
The Dirt Is Good To Me 
Iron is a wiley beast for several reasons. I never want to dig iron, because there is just so much junk out there, BUT never digging iron makes you miss out on awesome stuff like this little key. Now you have to find the treasure chest it opens. 🙂
You are so right. At my neighborhood park, I decided to dig every beep this Summer. I quickly gave up on that folly! Before I gave up though, I dug up a rusted clothes iron, you know, the ones that are basically a flat piece of iron with a handle attached to it and that you actually had to put on a fire to heat up. I also dug up a number of tilling blades from some old farm implement, not to mention the endless number of nails and barb-wire pieces. So yeah, the iron down there can be as interesting as anything but man! what a pain it is to dig!!
