how you know is copper there ?
need dig, maybe gold or silver surprise

Hello!! I have written it, I located it with the help of metall detectors and I have digging and I have seen it but I did not get it, fortunately the phenomenon was not lostOriginally posted by Morgan View Post

what size is the copper object?Comment

It's 15-20 cm plate of green Cooper, in the 20 cm deep...Originally posted by Morgan View PostComment

IR/UV LRL
with this copper plate you can play with diferent IR LED sensor until find a good one to filter that target, however there are many copper/bronze valuable objects that worth to dig...Originally posted by kostas87 View Post
I found a bronze lady near my oncle junk yard , I think maybe one aplique to use in old forniture, if I use LED filter didnt catch the object.Comment

Hello!!
yes I try, since I have the device I can do a lot of experiments on the photon multiplication. It has a lot of features ...
but I can't do much, my city is small and the electronics are very few here but I try. now I am making an amateur laser, there is a problem, I have found a strong receiver and the UV that cleans the underground metal is weak, and created a dead spot in the two steps near the buried metal, ie it cannot clean the atmosphere more than 2 meters and when I get close, the powerful receiver's speech signal from a distance stops. the( UV) can make a clear signal to some metals and kill some others like the sun do. Maybe we can make a kind of separation of metals, the type and size of each metal based on the spectrum and the energy intensity of the (UV) not only with IR but also IR type is the most important .this device it's have fun....Comment

does your LRL react to the ground when the ground color is near a white ?Comment

IR/UV LRL
no reaction to light colors, thats the best choyce of using special IR LED with filter ,comon IR LEDs pick whites colors and that no good for LRLsOriginally posted by abdou2014 View PostComment

you saw my videos with the IR locating targets in the field, there is no white shadows , yes metals irradiating energyComment

what you think if we remove the UV LED and install IR LED transmiter ?
I go to make a testComment

talking about white colors in the ground, you can see in this video MINUTE 1:29 the IR/UV system was calibrated under a shadow tree, ground is dark with many white and yellow branche spread all over the ground ,and same everywere,however IR/UV pick a signal ,a coin , of course if I move to a sunlight area the IR start beep becouse of INTENSE SUNLIGHT, so we need calibrate according place of searching conditions,thats obvious,

I mean a good IR transmiter 940nm, think some mineoro models using IR transmiters,for some reason...Comment

I'm not talking about a reaction for the colors but a reaction to the reflection of the sun's rays
there is not in the video directed the LRL towards the ground which is a white ground like the sand and the sun bursts without shade .
when we are in such a condition the LRL reacts i think because the reflection of the sun's rays is more important than in a dark ground .Comment

what is the role that the IR emitter can play, give the possibility of working at night and in winter, or to increase the detection distance ?
I believe that if we want to change the system and invest in the transmitter we must also change all the circuit and delete the IR receiver

we can use only the receiver, or use the transmitter and the receiver, and we can use only the transmitter, the three configurations work, but which is the best choice ?Comment
