You probably noticed that the wind shifted Thursday.  The tides are nice now, and the current prediction is for a 4 - 6 surf for Saturday.

Strong north winds of 20 to 25 mph with higher gusts will
produce increasingly rough, choppy surf, and a strong southward
flowing longshore current in the central Florida Atlantic surf
zone from early this afternoon through at least Friday evening.
Dangerous rip currents will also be present.

Wednesday morning I did a little more work on the recently cleared lot that is producing numerous railroad items.  It will take a while to just get the big stuff removed first.  

I was working on an area of nearly ten square yards that was covered with signals.  I dug many items (probably twenty or thirty) out of the area, but it seems there are just as many more remaining.  Besides spikes and bolts there seem to be a good number of wire loops remaining in the ground.  They are difficult to pinpoint.  I once found myself digging in the middle of a loop and hitting nothing before eventually finding the loop.

Under those circumstances I found myself using some techniques that I don't often use.  With numerous large targets and things like the wire loops buried in close proximity,  it can be difficylt to actually find items that are buried fairly deep.  In this case it sounded like targets were everywhere, yet when digging they weren't easy to find.  Some were pretty deep.  I cut way back on the Ace's sensitivity setting.  That filtered out many of the signals and let me focus on a few that were then easier to pinpoint.  That technique is similar to an old technique called detuning.  It is not quite the same thing, but the effect is the same. 

I also frequently changed modes on the Ace.  Moving from one mode to another, for example all-metals to coin mode, for example, provided more information about the target.  If I was using the Equinox or another detector that showed a conductance number that would have provided similar, but more precise information.  That is something like reverse discimination, bbut you can go back and forth between modes and switch to other modes.

Again, the Ace handles the electrical interference vrom the nearby powerlines well.  Eventually, I will switch to another detector - probably the equinox at some point, and maybe another detector as well. I Each detector has its strengths and weaknesses, and for inland sites having any promise at all, I always like to cover the area multiple times using different detectors.  I select detectors based upon the situation and upon the stage of the hunt.

I've said this before, but I always like to check any newly uncovered earth, and that includes earth dug up by gopher turtles or other animals.

Here is an excerpt from an article telling how a rabbit dug up ancient artifacts.

One of the objects turned out to be a “bevelled pebble” dating from the Mesolithic period that was probably used by hunter-gatherers about 9,000 years ago for tasks such as preparing seal hides for skin-clad watercraft or processing food such as shellfish.

The second was a shard from a bronze age burial urn around 3,750 years old. It will help experts build up a picture of past life on the island, which measures a mile by half a mile...

Here is the link for more about that.

I'll get out to take a look at some beaches before long.

Happy hunting,
