The Garrett® Ace 400 Metal Detector lets you go on a treasure hunt at the beach or in the field, with a 8kHz frequency that's ideal for discovering low and medium targets including jewelry, coins, relics, and other metal items. The Garrett Target-ID legend identifies targets as they appear on your LCD screen, and high-resolution iron discrimination with 40 levels helps sort trash from treasure. The improved 7" x 10" concentric search coil delivers enhanced coverage and detection depth, while Frequency Adjust allows you to toggle between various frequencies to eliminate interferences. The improved audio output gives you clearer target-ID tone signals.
