As a long time user of the original AT Pro International (not the gold or max because they have inferior audio) I can say this video is accurate. That being said, there are three things you never want to do with your AT pro when hunting in iron, or at all really.
The first is, never use any mode other than pro zero. Just don't do it......you'll find stuff but the amount of information you get from a target is halved in any of the bell tone modes.
The second is NEVER EVER use iron audio. It's a huge setback as you can see in this video. It turns your one inch detection zone into a one foot wide detection zone. I don't know if it's because the recovery speed drops horribly, or because fairies are doing calculus in the coil.......whatever it is, NEVER use iron audio.
The last is NEVER use discrimination if you're trying to hunt in iron. Again, your recovery time seems to die AND the audio comes out all delayed and poppy and sketchy and you don't get a real feel for anything under the coil other than large objects.
If you want to hunt iron with the pro you need to swing slow, pro zero, wide open and become one with the noise lol. Once you practice you'll be able to pick out keepers by detecting the unusual tone changes in the noise. Will you find everything? Hell no. With enough practice you should be able to find most of it assuming you're not too lazy to dig fairly sketchy but unusual sounds, since most of them won't be obvious dig me tones. I've run over my old AT pro sites with my Kruzer(similar to the anfibio) and I haven't found much that was missed, although I have found some, mostly in 4khz mode. I'll add to that, this is only on sites where I had the time to really work. If you only have a few hours on a site, you're not going to want to use the pro.
I still feel the pro performs better than some of the newer machines in a few areas(mostly urban) but for relic hunting in iron, or silver sniping at depth not so much.
Calabash, I do love your channel and vids. Maybe just for some piece of mind you could do this same test in pro zero, no disk, no iron audio to see if that dime pops up? Maybe I'm full of it but it's winter up here so I can't do it myself. I just need to know! I'm 90% sure it will.
