Yesterday I drove north to a large and very popular old beach, my expectations not all that high given the placed is routinely slammed by experienced detectorist using everything from 3030’s to modified Excals and even deep PI machines, but I like the place so I made the drive anyway, Excal and 12×15” SEF accompanying me.
This is a large freshwater beach where swimmers can roam more then 100 yards from shore, the area outside the ropes having a long tradition of moored boats and offshore parties, the participants tossing their bottle caps and pulltabs and whatever else over the side, so it is also rather trashy in spots, though the sand and silt is also deep so much of this trash sinks quite a ways. Out here it is only chest deep water, that depth of water where the adults gather, play and swim, just the type of area I’m always looking for.
So we have deep sand and silt, a lot of trash, a lot of adult swimmers, and this has been going on for at least 80 years or more. Just imagine what is laying on that firmer bottom below all of that sand a silt. This is what I was focused on, those really deep targets. If I had an 15×18” coil I would have certainly brought it, another item that’s still on my wish list but just not called upon enough to justify the expense, at least not yet.
The competition, hardly a scrap left in the first 10-12 inches of bottom, a few starting to show up here and there in that 12-14″ range, “a lot” showing up in 14 to 18” range, especially in those areas where the bottom has become so contaminated with deteriorating debris that these areas send the threshold into immediate and continuous convulsions. Most hunters simply walk away from these areas or they attempt to battle these areas by turning the sensitivity down, both of these practices just being self defeating in the end. There is a better way, a very effective way of dealing with this contaminated bottom. “Get rid of the threshold all together!”
Deep targets generate weak and/or faint returns, their signature being very small, often very-very small, quick, and quite faint. When your threshold is going crazy these very small and faint returns are too easily lost among all the chatter and instability in the threshold, this having the same effect regardless what mode you’re applying, pinpoint or disc. Adjusting the machine sensitivity has no effect on the threshold, all you’re accomplishing here is the filtering out of the those very small and very weak returns that you’re hoping to locate. Turning machine sensitivity down is a big mistake as this will only cost you many of those returns. Instead, just turn the machine threshold down to just below audible, this allowing for those really faint/weak/quick returns to stand out more clearly in your headphones. If you’ve not tried this then, literally speaking, you don’t know what you’re missing?
Nearly all of the targets in the image below were beyond the 12-14” range, this including 1 sterling ring, a 46 Rosie and a 42 wheat. No gold yet but it’s out there and I will find some of it. I’m sure of it. In a prior hunt I nabbed the 1896 Martinique coin in the other image. All of these targets, and more, passed over by those who routinely hunt this same freshwater beach. No doubt the place is still loaded with deep goodies and I’m going to continue to go after them. Here’s a link to the video detailing this strategy: https://youtu.be/32RyexwmVrs
Hope this article helps, and as always, good luck and be safe out there!
