Garrett Goldmaster 24k Metal Detector w/ 6" x 10" Coil Elliptical DD and 6" Round Concentric Coils with Garrett Carry Bag The Garrett Goldmaster 24k is a super sensitive gold detector, featuring the XGB Ground Balance System. Auto tracking system allows the GM24k to be used in a wide variety of ground conditions with more stable operation and less ground noise. Two audio modes allow you to choose from 2-tone “Beep” Mode to help distinguish target types or the Standard VCO “Zip” Mode, where audio pitch and volume rise as signal strength increases. Variable Self Adjusting Threshold to adjust the threshold recovery speed to help reduce the effects of changing ground mineralization. Rainproof metal detector with a waterproof search coil. The 6" Concentric Coil offers increased depth, target ID, and sensitivity over the 6×10 DD at the expense of extreme ground performance. The smaller shape is ideal for working brush, creek beds, and covering ground where micro nuggets may be hiding. On larger gold in mild ground this concentric coil may outperform the 6x10DD, but may require lower sensitivity levels in difficult (ferrous or alkali) ground.Bundle Includes:Garrett Carry BagIncludes:Headphones: Garrett 1/4" Wired Easy Stow Headphones with volume controlSearch Coil: Waterproof 6" x 10" Elliptical DD CoilSearch Coil: Waterproof 6" Round Concentric Coil8 x AA Rechargeable BatteriesAA Recharging Kit with Universal Adaptors12v Charger Cables for Car or BatteryFeatures:Frequency: 48 kHzWarranty: 2 Year LimitedGround-Sync: To quickly update ground settingsVolume Control: Fully adjustable, plus Boost optionsTraclock: To lock current ground balance settingThreshold Adjustment: Adjust to the level that fits your style of huntingAdjustable Iron Cancel: Feature for hot rocks, iron trashFrequency Shift: Use to reduce electro-magnetic interferenceBacklight: To view settings at night or in low lightSensitivity Control: Levels adjustable from 0 to 10
