Info from talking to Garrett Customer Service Rep:
The AT Pro has several search modes with various options. NONE of them are a true all metal mode, but there will be a "zero" mode.
While the AT will run at 15 Khz, it will NOT be using the 15khz groundhog circuit from the Scorpion Gold Stinger, which will continue to be manufactured.
SO, the AT Pro is NOT an update of the Scorpion.
It will be interesting to see how it does for prospecting without the all metal mode!!???
