Need advice with AT Pro

[Lenmcgold]

Bought my AT Pro in July. I am experienced with detectors, however need help/advice now. Problem is with discrimination. Here is situation - (when running in Std or Pro mode). I can use the factory settings and still have the same problems. It sounds off as if reading coins, 75-95 on digital readout, and the notch pointer goes to 70-90 as well. With iron audio on I still get the high tones and high readouts. When I dig 6-8" I still find nails and iron junk. Even more, when I move the iron disc. to 40 on the scale and notch out all the way to 55, it doesn't make any difference. Usually set sensitivity 2 notches below max. Going to Zero mode in Std or Pro doesn't help. Using 8X11in. DD coil. Use auto ground balance. What am I missing here? Appreciate help! Len

Are you ground balancing over clean ground? Try holding the power button until the machine beeps twice and resets. If either of those dont help it might be a defective machine. I had that problem with mine and had to send it in to garrett for repair. Their service is great. It was fixed at no charge and was back to me within a week

Thanks Jamie,
In fact, I did send my original unit back to Garrett. They sent me a new one. Great service! Unfortunately I remain mystified by the performance of my AT Pro.

You will get a high signal on rusty bottle caps and some nails. Switch to pro mode and never go back to standard. You'll eventually be able to learn the difference in sound between a good target and rusty target. With a bad target you'll hear the tone grunt, then spike high, then grunt again (this is easy to hear with iron audio on but also possible to hear without it on) I used to run it with iron audio off and if I got a target and wasn't sure I'd hit iron audio and check it. The silver tones will sound smoother and cleaner than junk.

I know exactly what you're talking about (with the grunt-high-grunt tone). Am I reading your post correctly that your advice is not to even bother popping in and seeing what these are? Is it at all possible that the grunt-high-grunt is a good target with some junk near it...sort of masking the good tone?

Whenever I skip one of those, I always get a second guessed feeling in my head, "Did I just pass up a good target?". I've been having my club members with White's running circles around me lately, even over ground I just went over, with a slow, smooth and steady approach, making sure my swings are level to the ground and overlapping each other.

I'm also anal about making sure the coil stays level at the end of my swing. I've hunted with guys from my club that swing fine through the middle, but at the end of each swing their coil goes almost perpendicular to the ground.

So your advice? Leave those grunt-high-grunts alone? Appreciate the input.

I would double check the grunt/high/grunts because indian heads and older wheaties will sound very similar. Whenever you get a signal that is questionable turn iron audio on for a sec and check it. Make sure that the location of the iron audio center is the same as the signal you were first hearing. There have been many instances where there was iron next to a target and you can hear the iron a few inches over from the good target once iron audio is on. As far as getting beat by whites it likely has to do with excperience or just pure luck for that day. You'll need to judge the performance off of many hours of hunting...

When I got my AT Pro,,, I started using it in the Pro mode,,, I wish my units didn't even have that Std, mode on it....
To me,,,the std mode turns it into a ACE 250,,, the Pro mode it what makes the AT so good in iron and rusty bottle caps,,,
and that's where I do most of my hunting...
