Ok what did I do wrong?

I've only had my Spectra about a week so I'm still a babe in the woods on running it. I'd just gotten done doing a little clad hunting and stopped at my buddy Bill's house on the way home. Bill and I have an 8in deep penny buried in his yard that we check our detectors with. We've used it for years. We took the Spectra out back and after GBing I swept over the penny. I didn't get a peep out of the Spectra. I was in the factory Coin and Jewelry program and the only mod I had made was turning on the multi-tone. I assumed that the sensitivity or gain just wasn't high enough. Bill wanted to try the detector so I turned it to single tone like he runs on his XLT. Bill swept the coil over the penny and the Spectra hit on the coin well and ID'd it too. I'm confused, why would multi-tone ID not register tone or VDI and single tone hit so well? Am I going to have to hunt in single tone to get the best depth?

How was the swing speed? I found with my test penny at 9.5 inches, my sweep speed makes a BIG difference on whether it picks up the penny and how well. Two different guys..two different swings. Did you try again yourself with the tone ID off? Did he try it with it on?

When it hit the penny for him I took the detector back and tried it myself and it worked well. I tried different sweep speeds when I was using multi-tine ID but I won't say that might not be the problem. I was swinging it about like I do my MXT.

Thats what I did to start with the V3. I had been accustomed to using a ridiculous swing speed with my XLT due to it being the 4 filter machine. To pick up that penny, I had to swing and swing fast. Out of habit I did that the very first evening with the V3 and was extremely disappointed that it wouldn't even register the penny at all. I went to bed frustrated, but in the middle of the night it dawned on me what I had done. Next morning I tried again with a much slower swing speed and it worked fine.

That was a learning thing for me also. Once the hiccups and learning curves settle out, have a feeling that this box will do amazing things for us. I'm still running across an occasional quirk and mostly it's a user thing.

I wouldn't think the Tone ID would make any difference on depth, but it might some how. The filter setting DOES affect the depth though depending on your swing speed and ground conditions. Re-read about the filters and try each one with your usual swing speed for the best depth and tone.
