Thanks to Bart at BBH and a newbie AT Pro question?

[samuel_schumaker]

First of all , Thank you Bart for fast and very great service, not to mention great pricing on the AT Pro and Pro Pointer, i received it on Wed and took her for a spin on my lunch hour yesterday to a local park. I do have a couple questions as im coming from a Minelab Explorer, one, I was running in pro zero mode with a little iron discrimination, i think around 30 or 35. Sensitivity two bars away from max, i dug two bottle caps that i thought sounded very nice. I did switch it to iron audio whenever i had good sounding 80-90 vdi numbers to try and tell the difference possibly between a bottle cap and a coin but i know its gonna take some time to understand it. When i turned iron audio on, i could still get a pretty nice clear tone on the bottle caps and it just seemed to make a bunch more noise in the surrounding area of the target like maybe there was more iron there then i knew. But the caps still sounded nice so i dug them. One was a budlight and one was a mikes lemonade, both were smashed flat tho and i wonder if that maybe made them sound a little better then they should have also. WIth my explorer i dont remember digging very many bottle caps at all, i swore they came up under zinc pennies on it but i may be mistaken. I do plan on digging pretty much anything but low iron numbers once i get the hang of the machine as thats why i bought a second detector, just for park and sports area hunting where im looking for jewerly and digging clad. The other question i have is, is the only thing different between pro zero mode with no discrimination vs. pro zero with iron discrimination and iron audio on? Would this be the same other then the point of where the mid tone starts? I wanna be able to at some point run it wide open and let my ears discriminate out the iron so that i can hear the good coins and such hiding in with it, i fell that no matter how fast a recovery speed and small of coil you have it would still allow you to hear more good targets then with using discrimination. If anyone has any suggestions i do appreciate them. Thanks, Sam

I should mention that i did dig some clad, a quarter, a dime and several zincolns, and they did make a great sounding repeating signal without much flutter in numbers, i just couldnt believe how good the bottle caps sounds compared to the quarter i dug

Try putting the coins along with the caps on the ground and listen to the sound while watching the vdi. The should be a difference in the sound.

The Iron Audio sounds are the low tones on each side of the target. Yes, it sounds good when you make a very narrow sweep (wiggle) so you are exactly over the target, but if you make a wide enough sweep you hear the low tones to each side. That is the Iron Audio sounding off telling you it is iron (ferrous).

 

[samuel_schumaker]

I understand it, and i did some more testing with it, only problem is, it seems if there is iron around the target you will get the same type of sounds. Basically if you switch to iron audio to check and decide wether its a coin or a bottle cap and you get the iron sounds before and after it could be a coin with iron or nails in the ground around it and you will be leaving a good target in the ground? Does this make sense? Basically you gotta dig it all to be sure

 

[MikeLab]

You will learn how that coil works. Yes, dig all iffy targets. Also highly recommended you learn in areas with lower trash levels.

[size=large]the bottle caps is mostly in the freq. 15 khz seems to love bottle caps. Mxt users have the same problem as it is near enough to the same freq. the ML is running all those others at the same time. seems to balance out the readings so you get better seperation. some machines have additional indictors others don't. from what i've read on the ATP, the caps are still a problem for most folks. some claim to have it figured out. sure wish someone would post a real good explanation for the rest of us to learn by.

I have no problem with bottle caps, have dug VERY few with the ATP. The tone is so distinct. Still get aluminum if it is small though, sometimes.

Got my AT-Pro about a month ago from Bart at BBH. Great price on the ATP and waterproof headphones. Real nice fella to deal with. Just got to try it out for the first time today....."I gotta really good feeling about this one!" Thank's Bart and happy hunting everyone.

Thanks Sam! Sorry I just saw this!

Lots of good replies here already but if you have more questions ALWAYS call me!

Enjoy it!

Remember that bottle caps will usually be shallow. 2" or less. I always hunt with iron audio off. If I suspect a bottle cap I turn iron audio on a most of the time the shallow bottle caps buzz or grunt when the left and right edges of the coil leave the target. If this happens take your probe and stab the cap and remove it, putting it in your junk pouch. Problem solved. Bottle caps ring up 76, 80, , 85 and shallow most of the time.

When I first get started coin shooting for the day I will get in too big of a hurry to find some goodies and the blasted bottle caps will fool me, especially the flat ones. I rarely switch to iron disc as the tone roll feature will usually help me out - IF I go slow and listen for the low high low tones. Set up a coin, jewelry and junk garden and take the time to listen to the signals. You will have to dig some junk using any kind of detector in order to find the goodies. Best wishes.
