Not so obvious spots to detect!
Beaches, whether they are of fine sand or pebbles, are places appreciated by predatory fish such as bass. The major difficulty on these beaches, which can be very large, is to find the potential area of activity. At first glance, everything looks the same with a vast expanse of sand or pebbles and the sea in the background.

However, if you look closely, you will see some current areas, darker areas indicating the presence of algae on the bottom. You must be even more attentive to the environment around you than you would be on the rocky areas in order to determine exactly where you can find a bass. Scrutinize the sky, the presence of birds hunting is often an excellent clue!
If you manage to identify an area with algae that could be home to some crabs, shrimp or anything else that could feed the bass, don't hesitate to insist around it.

Rarely posted fish
The major difficulty when fishing sandy or pebble beaches is finding fish posted like on a rocky area. Here, there are no rock piles to shelter fish, you can only rely on the presence of food.
You will have to cover as much ground as possible to optimize your chances of success and practice active fishing, i.e., make a few casts in one place and then move on, the goal being to cover the largest area possible.
To do this, casting far is essential and your rod/reel/bracelet set should be adapted. A rod long enough with a fine braid will help you gain casting distance.

Which lures to use ?
To cover the largest area quickly, using metal lures is an effective technique. These lures can be thrown very far thanks to their high density.

On the hunts, they are effective. Unfortunately, the fish below are not always very big.

When I want to insist on a particular area, I use the Black Minnow in size 3 (120 mm). This one allows a slower retrieve but also to change the sound and to stir the water thanks to its wide paddle. So many elements that do not leave the bass insensitive.

Generally speaking, Fiiish lures such as the Black Minnow, Crazy Sand Eel or Crazy Paddle Tail, are very suitable for beach fishing.

In summary
You will have understood that the beaches are not the easiest places to fish for sea bass, not that they do not harbor this wonderful fish, but simply because the reading of the spots requires a certain mastery and the fish that are present are very mobile. However, they remain very interesting places where it is possible to make nice fishing if you manage to reach a bird hunt not too far away. During the summer season these are areas to fish outside of the busy areas, so favor the sunrise or sunset to optimize your chances.
