In my opinion, beach and water reading skill's are just as important as your metal detecting technique.
They should compliment each other and be the combined factor that put you on the jewelry and coin hunting road to success.
I probably spend more time looking at beaches, than metal detecting on them, especially when I know I have an upcoming opportunity to go beach or water hunting.
With time spent searching a wide variety of beaches, you begin to learn what conditions on the beach increase your chances of recovering jewelry and coins.
Once you know what to look for, you can actively seek out certain areas at the beach likely to be better to search than other areas.
I am not just talking about low spots, which detecting forum experts are so fond of having Juan base his whole beach hunting plans on.
If there are no low spots or dips in the beach, and that is the only thing you look for it is probably not going to be a very productive beach hunt.
When the majority of beach or water hunters in an area are complaining about "Sanded in" conditions, the minority of beach or water hunters who can read a beach are probably still finding jewelry and coins.
There is always something to find somewhere at any beach, when you know where you should invest your time metal detecting.
Going back to that combined effort, people using good basic metal detecting techniques in good areas of the beach have more success recovering jewelry and coins.
Now would be as good a time as any for a shameless plug of my "How to read the beach & water" book. Available on my website, your local metal detector dealer, Amazon or Ebay.
