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.

Garrett AT Pro International Tones and Their Meaning



Having had the time to put some hours on the Garrett AT Pro International over a few months I've come to the conclusion that all detectors should come with a library of short audio clips to help new users to train their ears at home. Yes I know there are plenty of instructional video clips on youtube. But most of these videos have an audio stream that is out of sync with the video itself. Also many detectorists shoot videos that are far to dependent on the visual identification display on the detector itself. Im pretty sure that I'm not alone in saying that my hearing ability is far faster at processing the feedback from the machine then keeping my eyes glued to the detectors display looking at numbers that are displayed in a delayed fashion. In other words you hear the audio signal first and shortly after the display is updated. Yes the display is updated within milli seconds but I find this is enough to get on my nerves!

Anyway back to the topic of this post. The short audio clips below are examples of the feedback you get from your Garrett AT Pro International. I have used these to help me understand the makeup of the ground i am covering without the need to keep looking at the VID display. Also even though Garrett have a standard mode they recommend to new users I'd say just skip this mode and head straight into Pro Audio and learn from there.

I have included the STD audio clips just for reference.

So I hope someone might find these useful enjoy.

Cscope CS4PI Pulse Induction Metal Detector Review


Given the amount of beaches we have in Ireland (East Cork in particular) a pulse induction machine seemed to be the way to go.

The machine itself is pretty simple with an automatic ground balance system all the user needs to worry about is switching on and hitting the beach. There isn't a pin pointing mode but finding your target is pretty easy because of the concentric coil search head. Using the side step method you can get a pretty good fix on your target.



Best thing about this machine is that when it beeps there is something down there under the coil simple as that. It does suffer from the same drawbacks of other pulse induction machines there is no discrimination of any kind so just dig every target.

I've had a chance to take this detector to a location that has some very mineralized sections and as such sections are no go for other types of detectors I've used. I've taken this machine into the worst sections of the beach and found plenty of the normal junk that I'd expect to find all over the the rest of the beach. As above if it beeps there is a target that needs digging.

Other things to note.

The control unit is not water proof so just be aware of this. You can belt mount the control unit making the detector very light indeed. If the machine gets a bump it will give a prolonged beep that lasts for a few seconds (1-2) as it re balances this seems to be normal so don't worry too much when this happens.

The overall build quality is good with the upper stem being metal and the lower a tough plastic. The control box is made out of a really good quality heavy duty plastic. It can also be belt mounted (The machine is supplied with a little belt attachment). The search coil is submersible and comes with a scratch cover as standard.

Video Review:

Here is a review that I found helpful when I was making decision to purchase.

Minelab Quattro Target ID Bench Test and Review


Having recently purchased a used Minelab Quattro I was left feeling a little deflated after seeing the various reviews pointing out the units slow recovery time between targets. On top of this figuring what the target icons actually related to here in Ireland. So here is the data that I have.
All the information here is first hand. Taken in all metal mode with zero discrimination.



Minelab Quattro's recovery time. Its better than you think.

Minelabs Quattro's are considered to have very slow recovery times. While this appears to be somewhat true with regards to the preset search modes that supply the user with graphic target icons. If on the the hand the user runs the unit in "All Metal Mode" the recovery time between targets is more than acceptable and on par with other brands of machines of the same approx age. Numbers on the display are more or less the same weather using conductivity or fe detection modes. Reading stability is really good for this machine I find that some other brands can jump around like crazy example swinging over a target the display may jump between 20-21 for instance, But another machine (Garrett AT Pro International) may jump to many numbers all over its display range. Granted the Garrett AT Pro is far more sensitive to the composition, Shape and size of the target.
So the bottom line is that the Minelab Quattro is a fine machine that can be picked up for a more than reasonable price, it works well on land or along the beach so I'll be hanging on to mine for a good while to come.
