I posted another air test on youtube

Great Job! Thanks

[size=medium]It seems that john edmond air test was a lot better with the AT Pro international .........Than the air test on the AT Pros we are getting in the USA................. Could it be we are getting short changed here in the us..........[/size]Some one said that since the Scorpion and the AT Pro US are both 15KhZ on the frequency the AT Pro made for the US will not get any deeper than the scorpion.............................. Should i cancell my order for my AT Pro big question for me..........[size=medium]That air test was not as good as Johns The AT Pro for the US might not be up to par with the AT Pro international...[/size]

Thanks for your effort PD. Really appreciate your time. Enjoy that Pro.

Thank you for taking the time to do the test again. I am really liking what I am seeing. I have thought up a few of my own for when mine gets here. I know you are going to enjoy using your new detector.

Well, I'm gonna do a few more tests where I concentrate on keeping the target right at the 'sweet spot' in terms of the field from the coil. This is the middle but I noticed on my tests that sometimes I was a little low or a little high. I'll test that tonight with strict regards to what position the targets are across the coil. I suspect some depth changes may result.

One important thing to note though-the air test is not the end-all, be-all of a detector's performance!! So if one person's results aren't the same as another that doesn't always mean much. I would stop FAR short of thinking we in the US are getting short-changed vs. the UK based on a couple air tests! Seriously. I understand not wanting to lay out the cash till you see if the detector is everything you want it to be...just wait for us to get out into the field and make your decision on results in the dirt. Otherwise you may not really be happy with any detector you pick!

Maybe John didnt use a ruler and was guessing at air depths...who knows. I think the AT PRO would go deeper on coin size targets than the Scorpion due to the AT having a larger coil, which is equal to a 10-11" concentric coil. The Scorps coil is eaqual to a 7.5" concentric coil.

I think the more interesting test was when other things were introduced along with the coin. I am not all that much concerned with depth as such. It does no good for detector to reach a coin at 8 or 10 inches only to have it masked by a nail or something. The ability of this detector to deal with that is impressive.

I've asked John to give me all the details of his test so I can try to duplicate his setup. I'd hate to see everybody jumping through hoops for a Euro if there really wasn't any difference..

Jerry .....I think you "hit the nail on the head" !

I would rather have the AT that has such great featues
that help with target seperation that I am not much
concerned about depth.

The "tone roll audio" is one cool feature!

Ours should arrive in a few days!

I did my test in the coin (preset ground balance) mode, whipped those coins & rings at a fast speed and measured the distance at the first repeatable distance.

Until I see some field tests there is no point in jumping to conclusions. I would like to see someone do some tests with a bucket of dirt. Put the bucket on a couple of blocks and place your coin or ring underneath. That is about as close as you can get to a ground test.

I can't wait to see someone do a test using a test garden. That would be much better than a bucket of dirt especially if the targets have been in the ground for a while. I'll do a video on my test garden as soon as my machine shows up but I don't think that is going to be for another 10 days or so, even though I pre-ordered on October 1st, guess my dealer's distributor isn't on Garrett priority list :-(

I'll do that test even if it snows here New Hampshire by then - I have this amazing thing called a snow shovel that can be used to clear the snow off of a test garden in 10 or 15 minutes and I'll use that thing if I have to.

Air tests might be useful to learn what type of sounds the machine makes on different targets but air tests are an absolute, useless, waste of time for doing depth tests. The air does not produce any response - the ground produces a response that many, many times stronger than the target signal itself. Any detector, including the cheap chinese ebay detectors can air test to amazing depths. The true test of a detector is how deeply it can pick out that tiny, tiny target signal from the huge, huge ground signal. A quality detector gets good depth in the ground because it is built with good electrical parts that create an excellent signal to noise ratio, they have sophisticated ground filtering systems, the cheap detectors don't and that (among other things) is what separates a quality detector from a cheap one and you won't be able to see that same difference in an air test.

Another way to look at this air test thing is to compare it testing a car to see how fast it will go. Doing an air test is like jacking the drive wheels of the car off of the ground and then flooring it and looking at the speedometer and saying who my can go 120 mph easy. The real test of the car is to see how fast it can go on the road pulling its own weight, seeing how it handles air resistance, etc. The real test of a detector is to use it on targets in dirt to see how it the huge ground signal.

This fixation with air tests on this forum is just plain silly. And for anyone who is going to base a decision on which detector to buy based on an air test - hey I have got this great deal on a bridge for you
