A traditional trout fishing method is to simply fish it with a floating line. For this, you have the choice in the small trout equipment between cork floats or plastic floats of the "bubble" type. In cork, the most famous float is the Toulouse float, or simply a split ball which allows you to change it without dismantling the line, one of the most distributed brands is Water Queen. The "buldo" type floats are interesting because they are transparent, therefore discreet, and also because you can fill them more or less, which allows you to make it heavier to cast further. It is also often used to fish with a fly train, which means several flies in a row, in fresh water the limit will be 2 flies.
