Metal detecting depth
The depth of your metal detector should be set as high as possible. This means that this is so high that you don't experience excessive annoyance from irritating noises. This actually applies to all the areas you are looking on. On wet areas of the beach you will have to lower the sensitivity of most metal detectors in order not to get confused with the false signals.

How deep a metal detector maximum detects depends mainly on its size, but also the location and material of the object play a role. Also your swing speed slower = deeper and the working frequency lower = deeper influence.

In general, most detectors can find a copper coin at a depth of 8 to 12 inch. And large objects can still be detected with a good detector at a depth of more than 20 inch.

Deeper searching with your metal detector
The lower the frequency of your metal detector, the deeper the detector items can find. If your metal detector has a tone identification listens to hear how iron sounds, open the sensitivity and turn off the discrimination.

Search in the all-metal mode you can then go a little deeper than in the discrimination mode where the button is set to 0. What you can also do is think of a larger and/or a better search coil. This has pros and cons not every larger coil goes deeper than the smaller standard coil. Keep in mind that a larger coil usually detects the smallest objects less well.

You can also detect to greater depth by swinging your searching coil more slowly.

What also works well is hunting after a rainstorm or rather after a period of rain when the soil is wet. In wet ground, your detector always goes a lot deeper through the better conductivity.

With some detectors, you can also rotate a knob inside the cabinet to increase sensitivity, usually with a screwdriver. The Whites Surfmaster is an example of this.

Discrimination feature

In metal detection, discrimination simply means turning away certain objects / targets with a button on your metal detector.

It is not as simple as the above, because in theory you discriminate away metals with a low conductivity, in practice you simply discriminate weak signals. The result is that you still get a signal on a piece of iron even though you turn away the iron with low conductivity. A signal that gives an object back to the detector and thus causes a beep depends not only on the type of material but also on the size of the object, its location (slanted or flat in the ground), the depth, the degree of corrosion of the object and the type of soil you are looking for.

It is therefore possible that a coin at a certain level of discrimination may be squeaked at one time and not the next. For example in beach sand, a coin corrodes very quickly and can therefore be worse or not beep at all.

Even when a coin is standing upright in the ground, it can also happen that it does not beep. A coin standing upright in the ground often makes a double signal, but always a weaker signal than if it had been flat.

My advice is to set the discrimination on the material you want to find. If you want to find bronze items, set up the device on this roughly and you will probably also find copper or even silver coins with this position this is because the bronze coins are often very large.

Put items in the ground yourself
One way to be more certain is to try it out yourself. So put the objects you want to find in the ground yourself and test them in this way. The behaviour of your metal detector will then become clear more quickly. The discrimination setting and possibly notch or accept/reject setting will succeed better and you can go hunting with more confidence.

How can you find more in a shorter time?
How do you find a lot of treasure in the time you have at your disposal? Another difficult and unclear point. I can only say of this, find the right balance between swinging speed, walking speed, digging depth and discrimination. And also takes account of the terrain and the discoveries expected.

For example, on a dry beach you don't have to go for small beeps because most gold jewels are lost in the water. So you go there for coins, cell phones and that kind of stuff (the big beeps).

Then walk there quickly, swing fast, and take a large dish (at least 9 inch in diameter) It's a matter of making meters and discriminating so far until you only hear the bigger items from around a coin size. Also use a scoop with a long stem so that you are not always bent to dig. A big shovel looks tough but really not handy.

The XP with the 10.5 inch coil is perfect for dry beach, also because that detector has a quick recovery after a beep. Your swinging speed can therefore increase. And if there is enough, for example after it has been busy on the beach for a few days, it's better to go for the next beep than to dig half an hour on a very deep beep.

If you find out after a while that there is a lot of time between digging than you better go looking for a better place or lower your discrimination for more targets.

Another example:
If you are hunting in shallow swimming water. You can leave your scoop aside and dig by hand, this works super fast and results in many more finds.

More beach Tips
Go hunting in the evening and search at the beach when most swimmers are just away around 19:00. Then look at the prints of towels in the sand, as it is you most likely to find something.

Also look at places where most of the cans, chips and other rubbish that people leave behind are. Beach visitors usually don't want to walk far before they plunge into the sand so don't try to find too far from the steps that lead to the beach.

Another way to find items even faster on the beach is by using a pinpointer this is a device that allows you to locate an object in the dug hole. This works fine but if you can easily dig holes and if it doesn't matter how big the holes will be, you're probably faster with an extra scoop of sand than with the use of a pinpointer.

What can help to increase your recovery speed on the beach is to use a lightweight shovel on wet sand and a plastic scoop for dry sand.

Pinpointing feature
Pinpointing with a metal detector is something else than a pinpointer and you do it with a button on the detector itself. You use this to determine where the target is in the ground compared to your search coil.

In my opinion, this is an unnecessary option on a detector. With a little experience you can save a lot of your precious time in total by not pinpointing but by swinging back and forth to determine the position. Also when the target is in the side of the hole. You can then keep the coil at an angle and half in the hole to determine the location.

But it can be useful for very large objects if you want to measure how big something really is.

Hunting on large fields
There are many people who spend days searching in the same field. That is possible, but I do not think that is the best way. Other people seek out every inch from a field until they have had everything, this does not generally work either (only if you have a lot of time)

What does work?
If you start in a new field, first go over it quickly. In this way you don't find much, but you will find out the most quickly where something can be found (the big spots). Observe the shards, rubble, stones, height differences in the field, and the amount of iron nails in the ground.

After you have done this in just an hour you can start by carefully combing the field at these places where there is an increased risk of finding items.
Do you now find nice things in those places then look carefully and don't run away from those good places.

What I have also noticed is that in old fields it is worth looking for black spots with charred remains in the ground.

If you find a nice coin or item then just look right around it because often there are more of the same kind together.

If you did it right, at the end of the day you could put the best of the field in your bag. If you've been everywhere, stop and go to a new field or come back at most 1 or 2 times later if it was really good, But don't stay hoping that you can still find something, there are more fields waiting.

You can use the same field after the next harvest, after ploughing it again. The items may lie on the surface one year and lie deep again the following year, or vice versa.

Search for treasure spots using a Map
old maps for metal detecting
If you have just started metal detection, it is best to focus on the last century. A good way to find the better fields is to consult a map with heights. Something like the Topographical map of the united states.

It is best to go and look around the old towns and then visit the highest fields. These higher-altitude bumps are generally drier and therefore tend to house the better quality coins.

Look on the map also at the areas with fields that look very bad in terms of shape. Strangely shaped fields are usually older than the perfectly rectangular fields on the map.

You can also look at the water supply. In the past, the flowing water did not come out of the tap, but people had to walk to a creek or river and during this trip items were lost. Don't look too close to the river, because people didn't build houses there because of the risk of flooding. So look at the high fields a few hundred meters from flowing water.

What you can also look at are the street names. Old street names generally indicate that they were there at an early stage and are therefore indications of good treasure sites.
