The TC-120 diving metal detector
Thank you for choosing TC-120 diving metal detector. The TC-120 is a handheld metal detector. It was designed to pin locate metal (black and non-ferrous metal) objects during treasure hunting. The TC-120 can be used in combination with ground metal detectors to help discover metal targets. It has both sound and vibration to indicate the presence of metal objects. The vibration strength increases while it moves closer to the metal target. The detector has a 4.2-inch coil, which can detect small metal objects easily. It has LED flashlights, which helps detecting in dark or low light conditions. The TC-120 is diving grade waterproof. It provides reliable operation even in complex environments.
