Beach metal detecting secrets – Lugworms

I have been metal detecting on the beach for many years and in that time I have picked up some great tips and little secrets to increasing my finds on the beach.

All beaches can be different and you need to adapt these secrets to your given beach. With this in mind, here’s an interesting beach metal detecting secret I want to share with you. It will help you find more and it has certainly helped me over the years.


Look for the deep Lugworm
Yes, you read it correctly, ‘look for the deep lugworms’, which give their positions away with their sandy worm casts.

Believe it or not, the beach Lugworm can help you find those deeper and possibly more valuable finds, but How, I hear you ask?

It’s fairly simple but an effective way of finding areas to possibly concentrate on. The dark black sand that lies beneath the soft shifting sands of the upper layers of the beach can be very productive for finds of all sorts. This is because this hard packed dark sand traps finds that have worked their way through the finer upper sands and is usually out of the reach of beach metal detectors. The finds in these darken hard packed sands have also been there for some time, out of the reach of most metal detectors.

This layer of hard dark sand can lay undisturbed for years and only be brought into range of your detector by some of the violent winter storms. They can also be brought into range by the gentle erosion on some beaches which you would not notice if it wasn’t for the humble Lugworm.

Lugworm dig down into the sand and they can give away some clues to the dark dark sand beinglugworm near the surface in the form of worm casts on the beach.

We have all walked along the beach at some point and seen the Lugworm casts that resemble coiled worms made of sand.This is the Lugworm digging down into the sand and pushing the sand out in the form of these coiled casts. The worms don’t stop when they reach the darker sand and as a result the worm cast on the beach show the pushed out sand from these dark layers.

As a result, it gives away the position of the dark, hard packed sand near the surface. Not all beaches have lots of Lugworms or the correct conditions. If the beach does hold a Lugworm population, I would always advise you to keep your eyes open for the signs, and those darker Lugworm casts.

The dark hard packed sand is nearer the surface and could hold some great finds, it will certainly hold the older finds. This is one of my odder metal detecting secrets, but one that has helped on certain beaches.

Beach Search Patterns "How do you search yours?" Part 1#

Searching beaches can present a number of problems for the novice detectorist. The beach you're planning to search could be huge! Or maybe it’s covered in signs that you read about, scallops, tide marks, cuts and so on. Then again you may be on the clock. The great thing about learning about the beaches your search is that no matter what machine you use this information will stand to you for years to come.

The Quick Search.

If you are just scouting a new location or stopping by at a beach you always liked the look of. it can be more beneficial to target the more productive areas first. Areas such as the low tide mark, towel line, paths and handy seating locations. Remember even if you're only pulling up newer coins, pull tabs and other common junk targets. These finds can be very handy when you profile your new location.

Tip: always keep a small note pad and pen handy. Sketch your new beach and mark your finds and other characteristics roughly. You can review your notes later and build a new plan of action for next time.

If the location has common markers such as scallops, cuts, gravel bars and sand riffles hit these first and see what you come up with. Take note of the feel of the sand under your feet squashy soft sand normally means you're far from the hard pack and heavy gravel under the surface of the beach.

Items will sink down to the denser hard pack and rest there and your detector may not reach the entire way pass the sand overburden. This is why beach detectorist get weak in the knees after a storm has stripped the light sand from the beach exposing the hard pack and gravel.

If you’re new beach is smooth and relatively gravel free a new search pattern is required. A repeating "W" search pattern works out best.

This works well because you can cover larger portions of the beach looking for lines of targets. If you find a target halt the "W" pattern and search in a straight line for a bit. You may have found a streak of targets or a small pocket of targets. Some detectorist will search in a spiral pattern starting from the location of the first find.

Even if you are short on time during your session take five minutes to look over the beach from a vantage point. Just like your targets you should make a quick note of anything that stands out. When you head home fire up google maps and see if what you have experienced on the ground translates to patterns found on the map view.

Normal Search Patterns

On a normal day detecting on the beach I like to search left to right from the high tide mark following the tide as it heads out from the shore. Of course if you arrive on the beach and it has some nicely defined markers or it has been stripped I like to concentrate on those markers. I still follow the left to right pattern but only over these hot areas.

If you are digging targets look for changes in the sand, gravel or clay you are digging. I always find the good targets reside in the layer of dark, almost black layer of clay. This layer is below the gravel and crushed shell layer. Normally it stinks too! So you will know it forever more after that first time. This layer is so tightly packed that metals that the sea would normally devour can survive much longer.

Easy Homemade Gold Sucker

Other tube id 1 1/2″ type 125 PVC

Inner tube is 1 1/4″ Type 40 PVC
Length is about 3-4 feet.

The handle is made from 1/2″ PVC end caps and a 1/2″ tee with a couple of short pieces of 1/2″ PVC pipes to connect. The handle is bolted thru handle to the end cap.

Use 1/8″ file for O-ring grooves. Depth of O-ring grooves must be about 1/2 of the dia of the O-ring cross section. Note: I have excluded part numbers as this design is from 1994 and part numbers chance. Because of this you may need to have a poke around your local hardware providers to find an O-ring that gives the best seal.

With the crevice sucker attached, the plunger may be pumped several times until the material reaches the top of the 1/2″ pipe. Another possible attachment would be a 1 1/2″, 45 or 90 degree tool instead of the normal crevice sucker.

Since the gold sucker is normally used with the bottom open, you may be asking “how do you keep the stuff from falling out the bottom?” The short answer is ya gotta be quick. Try to keep your bucket or pan as close to the spot you are working ans almost submerged so you don't have to move the sucker very high or very far. It also helps if you can get into a rhythm where you are still pulling on the plunger while transferring the material. Clean up any material that falls out every now and then.

Credits for the design go to William F Westcott (1994)

Gold what is it, Where is it and How to Spot it.

Yes that's it, it doesn't look like much but it's been making people weak in the knees for thousands of years. The value of gold continues to grow because of its use in the electronics industry as a semi conductor.

The Properties of Gold

Gold is a very heavy yellow metal. It has a specific gravity of 19.3 this means that if you were to fill a test tube with gold it would weigh 19.3 times more times the weight of that test tube if it was filled with water. as a comparison lead (which we all know is heavy) has a specific gravity of 11 so gold is almost twice as heavy as lead. Gold is resistant to most naturally occurring chemicals so it doesn't tarnish and is never destroyed. Gold is also very malleable and ductile. It can hammered so thin that 250,000 sheets would make a stack just one inch high. One ounce can be drawn into a wire thirty five miles long. gold is never found pure in nature. It is usually found in a alloy along with copper, silver or platinum.

How do i know that the stuff in my pan is gold?

By its weight! - If you're panning technique is correct, the gold will be found at the bottom of the pan. As you gently swirl water around in your pan, gold acts differently than other material. It won't move as easily as the other material .
By its appearance - Because gold does not have much of a crystalline structure, it doesn't really sparkle or glitter - it shines. It also looks the same under in sunlight or the shade.
If in doubt, whack it with a hammer - extreme?. yes but, If it flattens, its gold. Now if it shatters, it isn't gold. This approach is not recommended.
You can drop it into some nitric acid. if it doesn't react it is probably gold. if it dose, it isn't. Nitric acid is pretty dangerous stuff so do not get it on you of breath the fumes. Be sure to follow proper handling procedures.

Once you see gold in your pan a few times you won't have any problems spotting it again.
