The float consists of a hollow body (2) with valve mechanisms for controlled admission of water (10) to its internal volume. At least one first opening (4) is formed at the lower end of the body, and a tube (6) passes slidably into the internal volume through a second opening (8) at the upper part of the body. The first hole includes a hollow tube (12) which forms a water circulation passage, and is surrounded by an elastic ring (14) which secures the lower end of the float to the fishing line (16), which also passes through an eyelet (18) at an intermediate position of the body. The ring also forms a ballast weight to maintain the float in an approximately vertically upright position.
