All the metal detectors in spite of model, brand or uses have the same components. The components are as follows stabilizer, control box, shaft and a search coil.

* The stabilizer is usually an arm brace and helps the unit to keep steady as it is placed over the ground.
* The control box is the brain of the detector and contains the circuitry, controls, speakers, batteries and a microprocessor.
* Shaft is a connecting material between the search coil and control box. It is adjustable and can be adjusted to the height of yours.
* The search coil is the actual part that senses the metal below the ground.

The cheap metal detectors contain the above components while the best rated metal detectors contain jack for headphones with computerized display and are more expensive. IF you people any other component of metal detector, it will be useful for all, hope you people give some response, thank you

i think its a good idea,however i dont think that every school should have to have one
i think if certain schools have a bad reputation,then they should be the schools who should install metal detectors,if schools are performing badly in exams,its usually because they have a bad reputation,it should be those schools who should get the metal detectors
