Haven't been detecting much the last few weeks, due to busy schedule and crappy weather.
Got out a bit this evening, and was rewarded with this manly .925 marked silver ring, weighs 11 g's.
It was within inches of a huge metal center support, the main one which has about 6 arms branching off, supporting the play structure.
My technique detecting around these large metal structures is to sweep real slow, and come within 2 inches of the metal.
The metal itself is sure to set if off, true ,,, But if a small metal object is there, it will struggle to make itself heard as well.
I was getting multiple dings, as well as jumping depth on the meter, so I knew something else was there and, sure enough, it was this.
My usual hunting grounds are pretty much my exclusive property, not many into detecting around here.
Of course, there may be guys going there that I'm not aware of, but in 4 years I've only seen 1 other guy, that was a couple years ago.
I almost felt like he was invading my territory, being used to being the only guy in the area with a detector ,,, But I realized that was pretty silly, as I, quite often, invade other guys "territory" with my own excursions.
I was walking my dog, and watched him as I walked by.
He was swinging unbelievably fast, I mean I don't think you could swing any faster if you tried.
His coil was a good 4 inches above the ground, and he looked to be missing his overlaps by about a foot or so ,,,, So if thats my competition, I don't think I have much to worry about anyhow.
Being so very close to that huge metal support, odds are most guys would not have found this.
Can't speak for other detectors, but with the 250, I've got the technique of detecting close to large metal objects down pat.
