My GB is always in the mid to high 90's. When operating in Pro many times, not always, I have to run sensitivity 3 or 4 bars below max to minimize falsing. In the same location I can run sensitivity at max or maybe 1 bar lower in Std. I understand the analogy of bright lights in fog but am curious if Std's filtering allows more sensitivity therefore getting better depth or am I hurting myself? I suppose the most practical answer would be to test it on my next hunt. Any thoughts or predictions?

When Pro is Unstable I can run Higher Sensitivity in Std, is that Good or Bad
- Thread starter flysar

Interesting.....I can always run my sensitivity higher in Pro Mode then Standard Mode. My Standard mode is the one that gets very unstable with high sensitivity. I have always referred the Standard Mode on the AT Pro as an ACE 250 on steroids. I would suggest you put a coin on top of your dirt and swing the coil above it until it fades, in both modes, then note the difference. The let all of us know. You may be on to something useful under certain circumstances.
I too have observed the same thing but only with my 5x8 coil. Worked with higher (almost full) sensitivity in standard mode then it did in pro mode but my standard coil has no such problem. However I did rectify the problem with my 5x8 coil by off setting the ground balance by about -5 manually and it worked amazingly well. I need to do this every time I swap from my stock coil to the 5x8 coil but hey it works a treat. Before this adjustment I could barely run 3 notches of sensitivity with the 5x8 coil where as now I can run almost max sensitivity. Strange as it seems but it works. By the way the 5x8 coil has a nose like a blood hound in trashy ground, love that coil.
Cheers!

Hmmm. I run Pro Zero mode all the time and like you, I have to keep it at least 3 clicks down from full sens, or I get falsing on the little sand ridges under water...never tried Standard mode..i have the stock coil...that said, I like how this thing hunts with those settings and the depth is amazing..I dont ground balance either....so I think its just our area, and the Pro has plenty of range built in to hunt hotter sens in a milder location...not good, not bad, just the way it is I think..

I haven't played around with the modes all that much. Pro zero with max sen. has worked well for me right out of the box and seldom have any serious falsing and the A T is about as sensitive on small (deep) targets as anything I have swung. On those small targets when playing with the sen I loose them when dropping down 2-3 bars. Small studs, 22 cal size lead, and so on. HH jim tn
I honestly do not know the answer the the question concerning sensitivity differences between Standard and Pro modes; HOWEVER, a couple of important notes concerning falsing that I have found:
- always ensure a good, deep connection for the coil wire to the box.
- watch out for temperature differences. What I mean is, if you take your overnight stored detector from a 70 F house instantly to, say, a 40 F outside hunting environment, a small bit of condensation can form inside the coil wire to box connection area. This can cause falsing, also. I try to always keep my detector in the garage at ambient temperatures during the spring, summer, and fall; however, when stored inside during most of the winter, I disconnect the coil wire, bring the unit in to the garage the night before, and re-connect before the hunt the next day.

I have found over the years of using many different detectors that no two are the same. Point my AT PRO. I turn on put in 0 STD MODE SENS full or -2 bars Ground Bal maybe if I remember (not kidding) and go .
today's finds 2/21/14 are as follows in socker field are 3 gold stud earring's about 4-6 inches deep 1-nickle 5 inches deep a bunch of clad 0-5 inches deep 1- junk brass girls ring. Never do I get any falsing.
the detector GODS HAVE BEEN GOOD TOO ME.
My deepest finds are around 10" deep on coins. On fresh water lakes as deep as 12-15" deep.
Most of the time falsing happens when coil wire is lose or bad and I do not use coil covers in water too much sand gets under them.
I'm here in central Virginia ground is good. Oh yes VIRGINIA BEACH IS A WHOLE DIFFERENT STORY SALT WATER IS NEVER EASY.

Out yesterday for 1.5 hours at an unimproved boat ramp just across the river from me. The hwy & bridge use to cross at that point so it was full of iron so it was tough to find a good clean GB area, GB was 94. ATP settled down in Pro Zero at 3 bars below max but the ID and tone on shallow coins (2" or less) was all over the place. Many times iron grunts mixed in, but I think it has a lot to do with the soil. I went to Std Zero and was able to operate 1 bar below max but I still got jumpy signals and tones when on a good coin target; "ding ding" drives me nuts. Coil wire is not moving, the first 8" is straight and velcro tied to the shaft before winding, and the plug is fully seated and finger tightened. Another thing I noticed was when using iron discrim at 35 and Pro Zero the iron tones would bleed through and sometimes report as high tones, in STD it was very quiet and only occasionaly falsing on the high tones. I did not use the stock coil because of all of the iron. This is my second AT Pro, sold the first because the "grass is greener" theory and it also operated the same in my immediate area. I think my basalt rock and volcanic ash area of the Columbia River Gorge is just some tough ground to work in. "nugget71" backing off the GB 5 to 10 manually didn't seem to have an effect on running smoother.

As already mentioned flysar, make sure everything is in place the way it should be and have a "good" set of Name Brand batteries in the machine. I run Duracells, and my MDing partner now runs energizers in his. He had to many issues running the no name brand battries and finally made the switch.
He was experiencing similar unstable issues as yours.
The only time I had a similar issue with my machine is when I switched coils ( 8.5x11 to 5x8 ) and forgot to do the required Factory Reset. Mine was getting a bit Funky before I figured out what my problem was, after the reset everything settled down, but I stillI have to reduce my sensitivity (2-bars) before I GB on the salted beaches. Once the GB is done, then i can increase my sens to max. Odd, but it works for my machine and my area (west coast).
Maybe something here can help with your machine.

I didn't know a factory reset was required when swapping coils, I'll try that and see what happens.
Thank you

I ran my ATP with both coils over my yard today. In most of my yard I couldn't run over 4 bars, regardless of mode, without a lot of chatter... some of it was repeatble feedback, iron maybe hot rocks? I also ran it over a section that has about 6" of clean fill and grass, not even a peep at full sensitivity. I suppose that would mean that there is just some nasty soil in the areas I've been hunting in recently.

There's a few times I have hunted early in the morning / the grasses have moisture on it and my AT PRO would chatter... only when swinging the coil, (PRO ZERO... HAD IRON DISC ON 40 max... sensitivity. max ). Went back to the same area late in the afternoon (no moisture on grass) and it doesn't chatter... Weird, couldn't figure out why. Don't know it this is relative to/same as your problem.

Another way of looking at this in bad soil flysar is that these machines (AT Pros) are very sensitive and why they perform well in most areas. What I found out about my machine early on, is that coil wire (using any coil) needs to run straight for about 6" up the shaft, then held in place snug (not tight) by something (I use Velcro) to keep the coil wire as straight as possible from the coil itself.
When I first got the machine I wrapped the wire around the shaft which put stress on the wire, at the coil, and it did react to every little thing it touched including water on the grass as mentioned by asiandigger. Once I sorted that out and ran the wire straight up the shaft for about 6", everything settled down. I sealed the wire at the base (coil) with Marine Goop, and I sealed my coil covers (both coils) with Black Automotive Gasket Maker.
Here is a picture of how I have my coil wiring running now flysar. This is a snap shot from a video I made for a friend of mine showing the AT Pro picking up a drain pipe 3' (measured) under this high mineral ground (balanced out at 93).
Hope this helps flysar:

The way I have the wire running from the control box on down is the way I run my machine in any enviroment whether it's the beach or the woods. I found this set up really helps my machine perform the way it should (or better).
As you can see in the picture flysar, I run the wire the same way from the control box out about 4 or 5 inches then it's velcro'd as well.
I really hope you get yours sorted out flysar because these AT Pros are very good machines for the buck that's for sure. I paid 3x more for a ML that didn't go any where as deep as this baby does. I sold the ML.
That's a great idea flysar in trying it out in different areas first, I think that would give you a pretty good idea which way to turn next.
Please keep us posted flysar, thanks.

Any word on your machine yet? Have noticed that alot with mine as well and been watching this thread. Dont know if the frozen gound, all the ice and snow have something to do with it but alot of times if I just bump the snow it sounds off a medium tone usually, sometimes a low grunt or mixed even. Albeit the 2 areas that actually show soil that we can hunt right now are littered with trash so I am waiting for nicer weather and more places to try it out to see. Just hope I dont wait til nice weather only to have to send it in and miss the first real stretch of good sunshine and thawed earth.
