Garrett Ace 300 Metal Detector

Garrett ACE 300 / 300i. It features a new 710 concentric PROformance searchcoil (larger than the standard coil previously offered on the ACE 250) for additional coverage and detection depth. The ACE 300 sports a higher frequency (8 kHz versus 6.5 kHz on the previous ACE 250) for better sensitivity to low and medium-conductivity targets.
