Seems like a good straight forward video..The at pro does have a tornado coil on it,but it’s as close to a 11 round as you can get,like the equinox and the 3030 have on them.

I dont think the shape of the coil makes any difference , they are all DD coils and the pro's stock 11 inch coil should have been an equal match. Far as I know , the only time a " round " coil should make a difference is if it was a concentric coil instead of a DD coil.
A couple things to note on this video. First , he did the noise cancel on the equinox with the coil sitting on the ground which is wrong.....would that affect performance ? ..... I dont know , maybe not. Second , he was in park 1 multi mode factory settings , the thing is this is just a starting point.....the machine can be further tweaked for better performance. The different mode and sensitivity settings alone make a huge difference , and if he set the nox in 5 khx single freq it would have hit every target well and possible slightly deeper , only in single frequency which I have found to hunt quite a bit deeper it does not have the multi freq advantage and it often calls bottle caps good coins. I also dont think I seen him ground balance the detector.
So the nox was used in a limited basic starting off point , noise cancelled wrong , not ground balanced , and with a smaller coil than the tornado on the AT pro. The Nox can be further configured to get a lot more performance out of it and matched to particuar conditions , while the Pro basically is what it is , you cant really go anywhere from there besides limited adjustments which may or may not help.
The guy claims its not a biased comparison , yet he has given every advantage to the pro possible and kept the equinox in a cage
He needs to open the nox up and turn it loose. I dont know enough about the other two detectors to comment on them. But this was not an unbiased comparison at all.
Something else that should be mentioned is that one the strengths of the equinox is target separation and unmasking. In just that aspect alone the equinox stomps the at pro hard......but you put that huge coil on the pro and you do get some extra depth , but you lose even more separation and masking ability......its fact , the more ground covered the more target masking and blending takes place. So while it works great on a single deep coin in clean ground or sterile test bed , put another object or two in there and now you often wind up with a target you may not even stop to investigate....if you hear it at all........Meanwhile the nox separates targets at depth well , even when there is some blending going on you can usually easily tell there are multiple targets. That is what is wrong with this type of test , they do give you a basic idea of a detectors potential , but only under the exact conditions of the test. Which is great if you only hunt sterile test beds
.....but you are rarely ever going to encounter a situation like that out in the wild.
I know your intended purpose was just to show that the AT pro can be a deep machine , and you are right it can be. I am not trying to pick this thread apart , just discussing some things I noticed on the video and some things that should be taken into account with the AT pro.
