Garrett Ace 300 Metal Detector with Waterproof Coil and Headphone Plus

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.
