WWI stuff, ETI561 in the field

[darkkitten2000]

On a dull rainy Saturday, I gave my new ETI561 a first true field condition test run. The chip plastic electro installation box I used has a neat property to be water tide, the only holes are those for loudspeaker and controls, so I wrapped it in a plastic bag, fixed by two rubber stripes, just to stay on a safe side, to keep my soldering iron cold. The slow rain was just persistent enough to keep the runners and supervisors off the public gym/fitness/running no-no park I hit for 2 hours. On some 150m of path I dug about 50 shallow holes none was deeper than some 20 or 30 cm, so no deep time consuming targets I always get when using one of my PIs. Good. I was hoping to find some coins and modern date trash, but most of targets ware small iron particles from WWI shells and grenades, I guess just rusty enough to give a nice clear “diamagnetic” signal on a BFO. The tiny ones are really difficult to spot being the same color as the dirt and works as really efficient time consumers. So I guess I’ll need an honest VLF with solid discrimination and depth assessment as a low end detector after all. Damn. None the less I found a spent Italian rifle round, an Italian rifle bullet (fired, some 20cm deep!! ) apparently a military uniform metal button (hit by something) and I picked one of the larger grenade particles (looks like a brown stone; it’s an iron chunk) just for display (left others behind).


Have fun,
