The Adams TZ-20 is a light-weight (6.4oz or 18 grams) compact metal detector that is truly pocket-sized: (11.5cm x 6.5cm x 3cm).
This model utilizes Adams new "APT" (active probe technology) operating system. It is simple to use and enables the operator to locate small or large metal objects with a speed and precision not normally associated with a low cost compact metal detector.
This new pocket-sized detector is suitable for a multitude of applications from general security and law enforcement work to other more diverse applications such as locating wires, pipes and conduit etc., buried beneath the surface of walls, ceilings and floors of buildings and other structures.
The TZ-20 gives a loud and clear audio/visual beep tone when a metal target has been located.
The TZ-20 has a single push button operation, with no further operational adjustments necessary for use.
The TZ-20 uses one standard 9 Volt battery.
