Sid.....I took you up on the challenge for a relic hunt only digging those high low signals. This was in Edmonton. I just scanned for the best operating frequency, set my sensitivity to full and pulled back a bit on the threshold, putting it in quiet mode. There were no shortages of signals, believe me. I hate saying this, as it has been repeated by so many people so many times, but here goes. This place has been hunted to death for the past 45 years, myself included. I have been skunked here on occasion recently, however, had pulled out some nice old silver, large cents and musket balls in the past. There were a lot of nails here, which I never realized. I used the iron check on each low-high signal. About half the nails wouldn't id as iron until they were brought closer to or at the surface. Larger targets, such as rotting tin cans did however ID as iron at greater depth. I dug only low high audio signals, hoping for copper or silver coins. Although I got a plethora of objects, no coins showed up. I did however dig up an old bakery token, a wonderful addition to my token collection. There were a lot of signals over all. As they did in the late 1800's, the homeless still continue to set up tents or build cheap shelters to survive here, until the Parks People evict them. They leave behind beer cans, pull tabs, cans, toiletries, tent pegs, tent poles, nails and many more items. Getting any good targets in these areas can be a challenge. Using a PI in this area is kind of unique, in that there is nothing indicating you to NOT dig any targets, like a VLF or Multiple Frequency with discrimination set. You just plug along (pun intended) and dig. You can rule out iron in some cases, streamline your search for silver, copper and some iron, or just dig it all. And that can make all the difference.
Here are some of the better finds. The temperature gauge was a cool find. I had visions of it being ripped out of an old car, thrown into the valley, only to be discovered years later. An old vintage Lipstick Tube, with some writing on the inside about Montreal. It was the cherry red color type, and had that same smell of the stuff my mom used to put on when I was a kid. The lighter...a Fisher Swing Line cigarette lighter, upon research, dates back to the mid 50's.
Below is my best find of the day....an old token, late 1800's to early 1900's.
