Making a test area for pistol

[Esteban]

You can create a test area for pistols (or other LRL instrument), for example, in this way:

1. Achieve 150-200 coins (cheaps) bronze and copper. Also can be some nickels.

2. Put in a plastic recipient with few quantity of the liquid (mixed with water) you use for to corrode copper PCB (we use here percloric salt of iron). Not acid. Instead it you can use common vinegar.

3. Move it with the coins and leave for 2 days in open space. Coins must be wet with the liquid. Take care with your clothes!

4. Quit all the liquid but no dry totally. Leave in air and Sun for 1 week or more at dry totally. Now you have green coins corroded artificially.

5. Put all it in a hole at 50 cm depth mixed with vegetable charcoal and common salt in big grains. Charcoal is for to absorb excess of humidity and salt is for to mantain humidity in dry epochs. Make this area far of iron objects. First, check this area and clean of big iron materials.

6. Put over it small quantity of water. Close the hole very well and mark the site properly for to remember where are buried the targets. You can use half brick over targets for to mark it.

7. Don't use common metal detector for to test this area, because the energy of oscillator consumes the "field". Rays of storm in the nearby also consume it. But always the energy is recovered through the time.

Don't know in wich time appears the phenomenon, maybe one year or more, but this is a good way.
