Hi All,
I had the chance to go today in a park in Sydney, to test how well the HH performs away from civilisation. Some of you may remember a previous post of mine. I went outside the building, in the yard to see how the metal detector works and I was disappointed to discover that every place where I was lowering the coil to the ground, it was beeping, like it found some metal. Today I got the confirmation, that indeed the yard is infested with junk bits and pieces to such an extent, that every square inch has some metal.
In the forest, I could lower the coil to the ground without any beeping at all! I placed a coin on the ground and I could detect it immediately (which means the detector was working
).
The first few signals I dug were some hot rocks. I took them home. One of them wasn't actually a hot rock, but a piece of construction concrete, with a bit of rusty metal showing on an edge. I used a file to confirm that was metal. That piece looked exactly like a natural rock, it must have been sitting there for quite some years.
The other two seem to be natural hot rocks. I split one apart with the hammer. It has a sandy constitution and has a colour close to a brick, with a dark band going through it and it shines in the light, like it has microscopical mirrors in it (maybe mica, I don't know). I will attach a photo for the ones curious to see how it looks like (and yes, I live in Australia, the land of hot rocks! ).
The other interesting thing I found today was a riffle shell. I checked with the magnifier on the back and it has written .303MK8Z and what it seems like Russian characters - PPU-85. To me it looks like a shell from AK47. This is to prove how far the Russian Mafia has spread!
I just did a check on the internet, and I found these shells presented here: http://www.municion.org/303/303Mk8zppu85G.jpg

They seem to be made Yugoslavia and they are for riffles.
I found out some more bits on the path. I think one is a wheel nut from a bike, another unknown item (I think it is a piece fallen from a UFO), a rusty metal cap, some rusty thin wire and a very large nail, zinc-plated.
I also found a rusty Allen key, most likely a herritage from the aboriginal people that used to leave in that area...
I got some more clear signals on the path in the park, but my wife acted like a hostile witness and got mad at my attempts to unveil those gold rings...
Next time I will have to find a more suitable partner of crime
And one last note about my coil. I noticed the maximum sensitivity of my coil is not in the center, but is about 4-5 cm closer to the right side. I suspect it has to do with the shielded cable that goes to the left side of the coil! Did anybody else experienced this effect? Toward the end of the day I was trying to see if I can detect some really weak signals in the forest, and I was getting sounds from the detector when I wasn't expecting anything. I ended up swinging the coil in the air very fast and strangely, it was beeping in one direction and not in the other one, or it was beeping toward the end of the swing. The conclusion is that something is not quite right, but I don't know what yet. I need to make the rod that holds the coil more solid and to put the coil into a housing.
Regards,
Nicolae
