Anyhow, I've had timing on my mind as it relates to beach detecting. Whether you hunt in the water or on the beach, timing can be very important. You will often want to time your hunt according to the tides.
Take a look at the above illustration. The waves will break where the water gets too shallow for the swells to proceed without being disrupted by bottom features. (I know that is a gross oversimplification, but it will serve for now.)
The waves will break where the water gets too shallow relative to the size of the swells Bigger swells will tend to break in deeper water, while smaller swells will break in more shallow water. You can therefore get a good idea of how deep the water is from where the waves are breaking and how big they are.
In the illustration above you can see the waves breaking where the water gets more shallow.
Here is the link that is the source of my illustration. You can also get more explanation there.
If the swells are small, like they were yesterday, the waves will break right in on the beach front where the water is very shallow. If the swells are larger, they will break in deeper water where the bottom rises.
I'll call the water area where the waves are breaking zone B. That zone can be narrow or broad and it can be in deep water or shallow water - again - depending upon the size of the swells and the shape of the bottom.
Zone A is the deeper water where the waves are not yet breaking. And zone C is where the water surges in after the waves break.
Unless the waves are small, it can be very difficult to detect in zone B. Waves that break over your head can be difficult to deal with. It can knock your ear phones off and generally make things difficult.
It can also be difficult to detect in the rushing water in the shallows if there are strong currents.
It is usually easier to detect in zone A if the water is not too deep for you. Zone A is where you'd find the recovery technique I described in my 9/20/14 post most useful.
Sometimes there will be a dip inside of a sandbar. After the waves break over the sand bar, the water in the dip can be fairly calm and easy to detect.
The three zones will change as the tide goes in and out depending upon a variety of factors that includes the changing depth of water.
How does that affect how you time your visit to the beach? Time your visit so that you can detect the zone that you want to detect. In zone A, for example, you will probably want to detect when the tide is out. Then you'll have more wet sand, but zone A will also now be where there was deeper water before and perhaps where the breaking waves were earlier.
If the waves are fairly big, you will probably want to detect when the breaking waves are not over the area where you want to detect. Maybe that will be on the sand bar.
Remember, as the tides get higher, the waves will tend to break in deeper water, and as the tide gets lower, the waves will tend to break closer to shore. Remember those three zones and think about how they can move with the changing tides.
One other thing I want to point out while I have this illustration up, is the sand bar can move in or out too. If you remember the experiment I did not long ago, the crashing waves will stir up the sand, causing the sand to move and causing objects to sink. Very often the waves will break on the one side of the sand bar, stirring up sand and pushing it in. In that case, the sand bar can move in towards shore, covering up things as the sand bar moves over them.
You know all of those unmatched ear rings that you've found. According to Kovels Komments, one high-end jewelry store is matching up vintage ear rings that go together well and selling them as a pair.
One thing I forgot to mention in my 9/20 post is that when you go with the flow, you don't have to hold onto your scoop if you have a scoop that will float upright. Get a scoop of sand in the bucket, and let the scoop go when you get washed off of the hole. Under normal circumstances, the scoop will be waiting for you when you get returned to the hole. You can therefore use it as a marker and not have to take the time to relocate the hole by feel.
It is still a good idea to have the scoop tethered to you in some manner.
As you can see, there is now some weather in the middle of the Atlantic that could develop. Today on the Treasure Coast the surf will be around two or three feet - a little rougher than it has been. It might increase a little more in about a week.
The low tides are not getting very low.
