Hi Wayne,
I have 2 AT Pro's and 1 AT Gold,,,,
one AT Pro with stock coil
2nd AT Pro with the 5x8 coil
and the AT Gold with the 4.5 coil...
Before I got the AT Gold, my AT Pro's
were one with the 5x8 and the other
with the 4.5 coil,,, before I got the 4.5
I only used the 5x8 coil..
Anyway, this area that I had been over like 10 times
super trashy,, and when I got the 4.5 coil, I went over
that same area,, and on my 2nd pass, I got a good sound
and dug this 14 K ring.....
And another time, my hunting buddy with a E Trac and the 11" pro coil,
said check this target,,I got a 74,,, he dug it, and it was a 7" deep zinc,
the 4.5 coil is my 2nd favorite coil,, the 5x8 is my first favorite...
The 4.5 has found me lots of good stuff in real trashy area's, that others have missed...
Some people told me it was not a very deep coil,, but a 7" zinc, is ok in my book..
Now this is in my soil,,, + or - 80 on the GB....
I love using my 4.5 coil....
BJ
