Garrett ATGold Metal Detector runs at 18kHz & has a sensitive 8"x5" DD coil making this an ideal selection as a first time, entry level or cheaper starter option for the process of gold detecting. This detector will happily cross over for a bit of coin or relic hunting as well. With its smaller coil & higher operating frequency this detector is sensitive to small shallow targets. AT Pro coils will fit straight onto this detector for a bit better surface coverage as well. Good for beginners!
