The term "swimming funnel" may not be a commonly used phrase and may require some explanation. However, there are various synonyms one can use to describe the same thing, such as pool noodle, float, or swim ring. These are all inflatable items often used by swimmers to provide buoyancy or support during aquatic exercises or leisurely activities. Another term commonly used for swimming funnels is a kickboard, which is a rectangular foam or plastic board used for swim training to practice the leg flutter and improve leg speed. Swimmers can also use hand paddles, swim fins, or pull buoys, which all fall under the category of swimming equipment.
