I just received a new to me SDC2300 and wanted to verify it using the Minelab security check on their website. I did not receive the viewer that was originally included with the detector so what worked for me was a coolant leak detector flashlight ( black light or UV light) It works well enough for me to read the hidden code and I was able to verify my machine.
I had a couple lead test targets for calibrating in the field but lost them on my last Western expedition. This is the main reason I don't use gold test targets! I'm ready to make a new set. I'd like to hear your advice on what size and shape of lead I should be using, for both LF and PI detectors.
I apologize to all my weak English
A few days ago I was on a journey to look for a gpz 700 golden device when I came across a large quartz rock I passed the device on the rock and issued the device indicating a clear target and the device was as follows
I switched the settings to make sure the target was metal and not an imaginary target
. It also gave me a clear target signal. I broke the rock into parts and it took me a great effort. I reached the desired part and the crystal was in the heart of the rock
Suddenly after I took out the desired part, I broke the piece in half and found that this material resembles mud and strange when I passed the device on the piece after I broke it the target signal disappeared and the device did not make any sound I tried to change the settings but to no avail the device kept silent
A question. Do any of you know these crystalline materials
And what is your interpretation of what happened
Thanks to all
I found this rusty looking rock in WI recently. It is heavy and is magnetic. It looks like it may have some small flecks of metal in it. I wanted to make a small window in it with a dremel or other drill to see. Wondering if this could be an iron stone meterorite or if it is some kind of geode? I'd welcome any advice. Thanks much! K
