The AD 16 Weapon and Metal locator has a pre-set turbo level, ideal for a really rapid search for small targets whereas the AD I7 has a variable turbo control for programmable detection.
Due to advanced technology, battery consumption is reduced to a level previously unattainable, allowing a minimum of I2 months daily operation from a single replaceable battery. This greatly reducing operating costs and improves convenience.
How do weapon and Metal detectors work?
Metal detectors work by transmitting an electromagnetic field from the search coil to the target area. Any metal objects (targets) within the electromagnetic field which will then become energised and retransmit an electromagnetic field of their own.
The detector’s search coil receives the retransmitted field and alerts the user by producing a target response. Most metal detectors are capable of discriminating between different target types and can be set to ignore unwanted targets.
Operating a metal detector is simple. Once you turn the unit on, you move slowly over the area you wish to search. In most cases, you sweep the coil (search head) back and forth over the target area in front of you. When you pass it over a target object, an audible signal occurs.
