Air Test 17" Coil vs 11" Coil

I searched the Internet for a test of the two coils against each other and could not find one. I am not much of a public speaker or actor so I opted out of making a video.

I bought the 17" Coil because I hunt mostly large farm fields. I hope to cover more ground quicker and a little more depth will not hurt.

 
I did an air test using a nickel. With a manual sensitivity of 30. With the 11 inch coil, I get 12 inches on the nickel and with the 17 inch coil, I get 15 inches on the nickel.

Thanks for the info. :)

Anyone who can possibly do a similar in the ground test comparing both the 11" and 17" 28-30 Sensitivity? I would also like to see those numbers. It will be helpful to others too. Thanks.

I second that!
 
in manual at 20, I get those or better with my tiny 6 inch coil testing in my basement :shrug: ...my numbers are up there with Terry in Hawaii! I really think the EMI you were apparently experiencing is the culprit?!?
 
In the field I can run at manual 30 and still have a stable CTX.
 
If no one has done any field tests with the specifications I was wondering about, would you mind doing it when you get a chance? :heh: Looks as if not to many people have done those sort of tests between those two coils based on the responses here. Hope the snow melts there pretty soon! :thumbup:
 
As soon as The snow melts. I will try to make a video in the field with my detecting partner. It will about 2-3 months before the snow and frost are gone. I live in Maine. Maybe some one in a warmer climate with both coils will read this and do the test sooner.

Yeah, that would be nice. What's your Youtube channel? I can subscribe so that I can see it when you do make it. Either way, I'll check it out just for reference.
 
I dug a measured 16" minnie ball on manual 30. The beauty of the ctx is outside around EMI with noise cancel I have been able to run mine 25-30 in places some detectors won't even function from EMI. I saw another indoor test done on auto and depth was poor so unless you can turn it up the test is not a good indicator of ctx depth.
