| 14K Diamond Bracelet Find. |
Here are a couple new beach finds. Above is a 14K diamond bracelet and below is a 14K aquamarine or maybe tanzanite ring. I'm not sure about the stone.

Yesterday afternoon there was a little erosion. My phone battery needed to be recharged, so I didn't get photos of the beach. I did get in a little detecting time for a change and picked up only shiny new targets, including a number or new coins. Absolutely nothing that appeared to be old at all.

In the past I did some posts about using all-metals or pinpoint mode as a primary search mode. Many people only switch to pinpoint mode when they want to pinpoint. Much of the time, I do it in reverse.
People like to the conductivity numbers and other target indicators you get when working in discrimination mode, but you can tell a lot about a target from just the auditory signal when using pinpoint mode. The more you use the pinpoint mode, the more you will learn to get from the auditory signal.
For years I used nothing but all-metals mode, even when using detectors that most people used mostly in discrimination mode. The Minelab Sovereign and Excalibur are two examples. The metal detectors that I used the most, though, did not provide any discrimination mode. They were designed to detect targets at depth in saltwater environments. They were designed for that single purpose and did it well.
When I started to write on this topic, I quickly found out it wasn't as easy as I thought it was going to be. One of the problems is that it is not always easy to describe some of the subtleties. Another difficulty comes from the fact that I am trying to describe how the detector operator perceives or hears the signal rather than the metal detector's output, which can be described in physical or electronic signals. I am trying to describe the experience in phenomenological rather than electrical or physical terms such as decibels or frequency.
There are a lot of individual differences. Some people have more acute hearing, for example. Some can discriminate more tones or frequencies. Personally, I not real good at discriminating tones or frequencies. I don't know how much of that is due to my sensory system, but it seems it is just not my nature to pay much attention to tones. I don't know how much of that is the result of spending so many years not paying much attention to the different signal tones, or if my sensory system is just not very good at that. I definitely don't have perfect pitch, but perception can be improved by training, and it can be affected by motivational factors.

Given all those acknowledged difficulties, I'll give it a shot and hope I don't make too much a mess of it. Remember, I'll be using phenomenological terms to describe the perceptual experience rather than the physical characteristics of the detector's output. They do not correlate perfectly.
From the auditory tone of the metal detector used in pinpoint mode, with some experience you can tell something about the size, shape and depth of targets.
Shallow targets generally produce stronger signals than deeper targets, and large targets generally produce stronger signals than smaller targets. That is obvious, but there is more to it than that.
A signal produced by a small shallow target will be strong, but also brief and crisp. I might call that "sharp." That is a subjective or phenomenological description. It is something that I can not describe in objective measurable terms like decibels or frequency, or other physical terms. It is a subjective perception.
The brevity and crispness of the signal makes such a target sound even "stronger" than you might expect given the number of decibels produced by the output device of the metal detector. A more prolonged signal of constant decibels would not be perceived as quite as loud as a sharper signal of the same decibel level.
As the depth of the target increases, the signal will be less loud, but less "sharp" or distinct. The signal start and end less abrupt. It is more gradual. I'd describe it as being more fuzzy. As the coil moves onto and away from the target, the signal from a deeper target will not be as crisp as one from a more shallow target.
Using the combination of loudness, signal duration and distinctness, you can get a good idea of depth and size. Holding the size of the target constant, if it is deeper, the signal will not be as loud, but it also will be less crisp. If it is a large topic, the signal will have greater duration.
Of course, noise will tend to disguise good signals, especially when they are less distinct, but many targets, such as smaller and shallower targets will still tend to be easily perceived among the noise.
I haven't said anything about how to tell the shape of the target from the signal yet. I've described various methos of doing that in other posts. There is the double blip of thin long objects, for example. And by slowing tracing across the object in various directions, you can get some good information about the object's size and shape. Most people these days know how to change sweep direction to tell if an object is roundish. I described that technique many years ago. To examine the object's shape, move the coil very slowly in various directions over the object. You will not be able to determine the shape of smaller objects using that method.
You can get all that information from the signal if you want to, but don't spend to much time on it, especially since you can simply scoop it up and see what it is. In cass when it sounds like it will not be so easy to dig up, you might want to spend more time determining the nature of the buried target before making the decision to dig it.
With time, this will all become second nature. Tasks that are frequently performed tend to become automatic, which is one reason I found it so difficult to break it down and describe the basic processes. I did it so long, it is very automatic for me. It is something like trying to describe how to ride a bike. You can't describe how to do it. You aren't even aware of all the adjustments you make. But if you pay careful attention to the signals and how they vary according to the targets, you'll learn how to tell a lot of about the target from the auditory signal in all-metals mode.

We had a wind shift yesterday and there was some small erosion on one of the beaches I visited. It wasn't much, but enough to help in areas where there has been a lot of recent traffic.

As you can see, a little increase in the surf is expected but it won't be a lot and it won't last long.

The Make America Dead agenda is in high gear and innocent children are being slaughtered around the world. Evil is enraged and knows it's time is short.
Matthew 2:16 Then Herod, when he saw that he had been tricked by the wise men, became furious, and he sent and killed all the male children in Bethlehem and in all that region who were two years old or under, according to the time that he had ascertained from the wise men. 17 Then was fulfilled what was spoken by the prophet Jeremiah:
18 “A voice was heard in Ramah,
weeping and loud lamentation,
Rachel weeping for her children;
she refused to be comforted, because they are no more.”
But as Easter approaches, we know that death will be swallowed up in victory.
