Metal detector PI 807-KIT Do-it-yourself
Microprocessor impulse metal detector with excellent characteristics. Construction KIT. It characterizes with an excellent stability of work, great depth detections. It works in mode "all metals". The PI 807-KIT can be constructed and ready for use without the use of a soldering-iron or a screw-driver. Any knowledge on electronics is not necessary.
Characteristics:
-
Full control of the microprocessor on the device's work
- Two potentiometers for additional settings -- sound volume and sensitivity (depth)
-
54 programmable settings parameters. All manually chosen parameters are automatically saved by the microprocessor. When switched on again, the metal detector works with the previously saved parameters.
-
The metal detector can work with the default parameters. It is not necessary to be changed.
-
You can choose between two types of coils -- round 11 inches, square 40 inches. The chosen coil is automatically saved by the microprocessor. When switched on again, the metal detector uses the saved coil.
-
Option to work with an internal speaker.
-
Option to work with additional headphones.
-
Works with 12 rechargeable batteries type AA; 1,2V; 2000mAh

Consists of :
- main scheme plate 94mm x 115 mm
- control and indication scheme plate 48 mm x 115 mm
- connection cables
- two coils without bodies with a protected cabel connected with the metal detector and input for plugging the metal detector in. The coils are with a size of 26 cm round and 100x100 cm square
- 3 mm headphones input
- construction manual
- use instructions
Constructing the PI 807-KIT :
-
Installing the main scheme plate and the plate for indication and control in a specially chosen box
-
Installing the inputs for the headphones and the coils in the box
- Installing the high-speaker in the box
-
Installing a 26 cm coil in a body or wrapping it with a bandage tape, or coating it with epoxide resin
- Installing in a body of PVC pipes the square 100 cm x 100 cm coil or mounting it on the outer side of the PVC pipes
-
Installing the rechargeable batteries in the box
Switching the metal detector on:
- Connect the coil via the listed in the instruction conductor, to the matching input of the metal detector
- If you're not using a high-speaker , plug the headphones in the matching input
- Turn the sound volume resistor to max left
- Turn the depth resistor to max left
- Switch the power supply on
- Wait for approximately 15-30 seconds
- Turn the sound volume resistor to one quarter to the right
- Turn right smoothly the depth transistor, until you can permanently hear sound
- Turn back left until the sound is off
- The metal detector is ready for use
