The mission

Our first assignment and I am so excited!!!

Our friend Wendy's sister had lost her silver necklace when she was a child in her mother's backyard. Tonight we planned to meet with them and our metal detector. As we drove up there was quite a crowd awaiting curbside to watch us pull out our sleek metal detector. They chatted and followed us around the yard looking over our shoulders at the numbers on the display.
I was detecting and Mary was digging.
I wanted to be cautious to not to instruct her to dig too many holes as their mother watched us with great anticipation.
But I was having problems.
The readings just weren't happening.
I checked the knobs and road the threshold hum listening to each blip and crackle.
Re-checking the metal types and purity of the signals I was finding.
I was discovering nothing but iron, low foil and scattered metal readings.
I checked the machine with a fire hydrant - Yep! That had a strong,true signal.
Aluminum ladder - Wow! Aluminum is '94' on the detector scale.
Old lawnmower - had a good signal too.
Why could I not find anything else?

I only have had a couple hits on the whole property (I strayed onto the neighbours property too).

I wanted to do well.
I wanted to be a hero.
I wanted to accomplish this mission and prove that Mary and I are worthy metal detectors.

Besides clipping of metal sideing, the picture below is all we found.
